The present invention relates generally to control of a pump, and more particularly to control of a variable speed pumping system for a pool.
Conventionally, a pump to be used in a pool is operable at a finite number of predetermined speed settings (e.g., typically high and low settings). Typically these speed settings correspond to the range of pumping demands of the pool at the time of installation. Factors such as the volumetric flow rate of water to be pumped, the total head pressure required to adequately pump the volume of water, and other operational parameters determine the size of the pump and the proper speed settings for pump operation. Once the pump is installed, the speed settings typically are not readily changed to accommodate changes in the pool conditions and/or pumping demands.
Installation of the pump for an aquatic application such as a pool entails sizing the pump to meet the pumping demands of that particular pool and any associated features. Because of the large variety of shapes and dimensions of pools that are available, precise hydraulic calculations must be performed by the installer, often on-site, to ensure that the pumping system works properly after installation. The hydraulic calculations must be performed based on the specific characteristics and features of the particular pool, and may include assumptions to simplify the calculations for a pool with a unique shape or feature. These assumptions can introduce a degree of error to the calculations that could result in the installation of an unsuitably sized pump. Essentially, the installer is required to install a customized pump system for each aquatic application.
A plurality of aquatic applications at one location requires a pump to elevate the pressure of water used in each application. When one aquatic application is installed subsequent to a first aquatic application, a second pump must be installed if the initially installed pump cannot be operated at a speed to accommodate both aquatic applications. Similarly, features added to an aquatic application that use water at a rate that exceeds the pumping capacity of an existing pump will need an additional pump to satisfy the demand for water. As an alternative, the initially installed pump can be replaced with a new pump that can accommodate the combined demands of the aquatic applications and features.
During use, it is possible that a conventional pump is manually adjusted to operate at one of the finite speed settings. However, adjusting the pump to one of the settings may cause the pump to operate at a rate that exceeds a needed rate, while adjusting the pump to another setting may cause the pump to operate at a rate that provides an insufficient amount of flow and/or pressure. In such a case, the pump will either operate inefficiently or operate at a level below that which is desired. Additionally, where varying water demands are required for multiple aquatic applications, the water movement associated with such other applications can be utilized as part of an overall water movement to achieve desired values. As such, a reduction in energy consumption can be achieved by determining an overall water movement within the pool, and varying operation of the pump accordingly.
Accordingly, it would be beneficial to provide a pump that could be readily and easily adapted to provide a suitably supply of water at a desired pressure to aquatic applications having a variety of sizes and features. The pump should be customizable on-site to meet the needs of the particular aquatic application and associated features, capable of pumping water to a plurality of aquatic applications and features, and should be variably adjustable over a range of operating speeds to pump the water as needed when conditions change. Further, the pump should be responsive to a change of conditions and/or user input instructions.

The foregoing and other features and advantages of the present invention will become apparent to those skilled in the art to which the present invention relates upon reading the following description with reference to the accompanying drawings, in which:
Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. Further, in the drawings, the same reference numerals are employed for designating the same elements throughout the figures, and in order to clearly and concisely illustrate the present invention, certain features may be shown in somewhat schematic form.
An example variable-speed pumping system 10 in accordance with one aspect of the present invention is schematically shown in
The swimming pool 14 is one example of a pool. The definition of “swimming pool” includes, but is not limited to, swimming pools, spas, and whirlpool baths. Features and accessories may be associated therewith, such as water jets, waterfalls, fountains, pool filtration equipment, chemical treatment equipment, pool vacuums, spillways and the like.
A water operation 22 is performed upon the water moved by the pump 16. Within the shown example, the water operation 22 is a filter arrangement that is associated with the pumping system 10 and the pool 14 for providing a cleaning operation (i.e., filtering) on the water within the pool. The filter arrangement 22 is operatively connected between the pool 14 and the pump 16 at/along an inlet line 18 for the pump. Thus, the pump 16, the pool 14, the filter arrangement 22, and the interconnecting lines 18 and 20 form a fluid circuit or pathway for the movement of water.
It is to be appreciated that the function of filtering is but one example of an operation that can be performed upon the water. Other operations that can be performed upon the water may be simplistic, complex or diverse. For example, the operation performed on the water may merely be just movement of the water by the pumping system (e.g., re-circulation of the water in a waterfall or spa environment).
Turning to the filter arrangement 22, any suitable construction and configuration of the filter arrangement is possible. For example, the filter arrangement 22 can include a sand filter, a cartridge filter, and/or a diatomaceous earth filter, or the like. In another example, the filter arrangement 22 may include a skimmer assembly for collecting coarse debris from water being withdrawn from the pool, and one or more filter components for straining finer material from the water. In still yet another example, the filter arrangement 22 can be in fluid communication with a pool cleaner, such as a vacuum pool cleaner adapted to vacuum debris from the various submerged surfaces of the pool. The pool cleaner can include various types, such as various manual and/or automatic types.
The pump 16 may have any suitable construction and/or configuration for providing the desired force to the water and move the water. In one example, the pump 16 is a common centrifugal pump of the type known to have impellers extending radially from a central axis. Vanes defined by the impellers create interior passages through which the water passes as the impellers are rotated. Rotating the impellers about the central axis imparts a centrifugal force on water therein, and thus imparts the force flow to the water. Although centrifugal pumps are well suited to pump a large volume of water at a continuous rate, other motor-operated pumps may also be used within the scope of the present invention.
Drive force is provided to the pump 16 via a pump motor 24. In the one example, the drive force is in the form of rotational force provided to rotate the impeller of the pump 16. In one specific embodiment, the pump motor 24 is a permanent magnet motor. In another specific embodiment, the pump motor 24 is an induction motor. In yet another embodiment, the pump motor 24 can be a synchronous or asynchronous motor. The pump motor 24 operation is infinitely variable within a range of operation (i.e., zero to maximum operation). In one specific example, the operation is indicated by the RPM of the rotational force provided to rotate the impeller of the pump 16. In the case of a synchronous motor 24, the steady state speed (RPM) of the motor 24 can be referred to as the synchronous speed. Further, in the case of a synchronous motor 24, the steady state speed of the motor 24 can also be determined based upon the operating frequency in hertz (Hz). Thus, either or both of the pump 16 and/or the motor 24 can be configured to consume power during operation.
A controller 30 provides for the control of the pump motor 24 and thus the control of the pump 16. Within the shown example, the controller 30 includes a variable speed drive 32 that provides for the infinitely variable control of the pump motor 24 (i.e., varies the speed of the pump motor). By way of example, within the operation of the variable speed drive 32, a single phase AC current from a source power supply is converted (e.g., broken) into a three-phase AC current. Any suitable technique and associated construction/configuration may be used to provide the three-phase AC current. The variable speed drive supplies the AC electric power at a changeable frequency to the pump motor to drive the pump motor. The construction and/or configuration of the pump 16, the pump motor 24, the controller 30 as a whole, and the variable speed drive 32 as a portion of the controller 30, are not limitations on the present invention. In one possibility, the pump 16 and the pump motor 24 are disposed within a single housing to form a single unit, and the controller 30 with the variable speed drive 32 are disposed within another single housing to form another single unit. In another possibility, these components are disposed within a single housing to form a single unit.
It is to be appreciated that the controller 30 may have various forms to accomplish the desired functions. In one example, the controller 30 includes a computer processor that operates a program. In the alternative, the program may be considered to be an algorithm. The program may be in the form of macros. Further, the program may be changeable, and the controller 30 is thus programmable. It is to be appreciated that the programming for the controller 30 may be modified, updated, etc. in various manners. It is further to be appreciated that the controller 30 can include either or both of analog and digital components.
Further still, the controller 30 can receive input from a user interface 31 that can be operatively connected to the controller in various manners. For example, the user interface 31 can include a keypad 40, buttons, switches, or the like such that a user could input various parameters into the controller 30. In addition or alternatively, the user interface 31 can be adapted to provide visual and/or audible information to a user. For example, the user interface 31 can include one or more visual displays 42, such as an alphanumeric LCD display, LED lights, or the like. Additionally, the user interface 31 can also include a buzzer, loudspeaker, or the like. Further still, as shown in
The pumping system 10 has means used for control of the operation of the pump. In accordance with one aspect of the present invention, the pumping system 10 includes means for sensing, determining, or the like one or more parameters indicative of the operation performed upon the water. Within one specific example, the system includes means for sensing, determining or the like one or more parameters indicative of the movement of water within the fluid circuit.
The ability to sense, determine or the like one or more parameters may take a variety of forms. For example, one or more sensors 34 may be utilized. Such one or more sensors 34 can be referred to as a sensor arrangement. The sensor arrangement 34 of the pumping system 10 would sense one or more parameters indicative of the operation performed upon the water. Within one specific example, the sensor arrangement 34 senses parameters indicative of the movement of water within the fluid circuit. The movement along the fluid circuit includes movement of water through the filter arrangement 22. As such, the sensor arrangement 34 includes at least one sensor used to determine flow rate of the water moving within the fluid circuit and/or includes at least one sensor used to determine flow pressure of the water moving within the fluid circuit. In one example, the sensor arrangement 34 is operatively connected with the water circuit at/adjacent to the location of the filter arrangement 22. It should be appreciated that the sensors of the sensor arrangement 34 may be at different locations than the locations presented for the example. Also, the sensors of the sensor arrangement 34 may be at different locations from each other. Still further, the sensors may be configured such that different sensor portions are at different locations within the fluid circuit. Such a sensor arrangement 34 would be operatively connected 36 to the controller 30 to provide the sensory information thereto.
It is to be noted that the sensor arrangement 34 may accomplish the sensing task via various methodologies, and/or different and/or additional sensors may be provided within the system 10 and information provided therefrom may be utilized within the system. For example, the sensor arrangement 34 may be provided that is associated with the filter arrangement and that senses an operation characteristic associated with the filter arrangement. For example, such a sensor may monitor filter performance. Such monitoring may be as basic as monitoring filter flow rate, filter pressure, or some other parameter that indicates performance of the filter arrangement. Of course, it is to be appreciated that the sensed parameter of operation may be otherwise associated with the operation performed upon the water. As such, the sensed parameter of operation can be as simplistic as a flow indicative parameter such as rate, pressure, etc.
Such indication information can be used by the controller 30, via performance of a program, algorithm or the like, to perform various functions, and examples of such are set forth below. Also, it is to be appreciated that additional functions and features may be separate or combined, and that sensor information may be obtained by one or more sensors.
With regard to the specific example of monitoring flow rate and flow pressure, the information from the sensor arrangement 34 can be used as an indication of impediment or hindrance via obstruction or condition, whether physical, chemical, or mechanical in nature, that interferes with the flow of water from the pool to the pump such as debris accumulation or the lack of accumulation, within the filter arrangement 34. As such, the monitored information can be indicative of the condition of the filter arrangement.
In one example, the flow rate can be determined in a “sensorless” manner from a measurement of power consumption of the motor 24 and/or associated other performance values (e.g., relative amount of change, comparison of changed values, time elapsed, number of consecutive changes, etc.). The change in power consumption can be determined in various ways, such as by a change in power consumption based upon a measurement of electrical current and electrical voltage provided to the motor 24. Various other factors can also be included, such as the power factor, resistance, and/or friction of the motor 24 components, and/or even physical properties of the swimming pool, such as the temperature of the water. It is to be appreciated that in the various implementations of a “sensorless” system, various other variables (e.g., filter loading, flow rate, flow pressure, motor speed, time, etc.) can be either supplied by a user, other system elements, and/or determined from the power consumption.
The example of
Within another example (
It should be appreciated that the pump unit 112, which includes the pump 116 and a pump motor 124, a pool 114, a filter arrangement 122, and interconnecting lines 118 and 120, may be identical or different from the corresponding items within the example of
Turning back to the example of
Although the system 110 and the controller 130 may be of varied construction, configuration and operation, the function block diagram of
The performance value(s) 146 can be determined utilizing information from the operation of the pump motor 124 and controlled by the adjusting element 140. As such, a feedback iteration can be performed to control the pump motor 124. Also, operation of the pump motor and the pump can provide the information used to control the pump motor/pump. As mentioned, it is an understanding that operation of the pump motor/pump has a relationship to the flow rate and/or pressure of the water flow that is utilized to control flow rate and/or flow pressure via control of the pump.
As mentioned, the sensed, determined (e.g., calculated, provided via a look-up table, graph or curve, such as a constant flow curve or the like, etc.) information can be utilized to determine the various performance characteristics of the pumping system 110, such as input power consumed, motor speed, flow rate and/or the flow pressure. In one example, the operation can be configured to prevent damage to a user or to the pumping system 10, 110 caused by an obstruction. Thus, the controller (e.g., 30 or 130) provides the control to operate the pump motor/pump accordingly. In other words, the controller (e.g., 30 or 130) can repeatedly monitor one or more performance value(s) 146 of the pumping system 10,110, such as the input power consumed by, or the speed of, the pump motor (e.g., 24 or 124) to sense or determine a parameter indicative of an obstruction or the like.
Turning to the issue of operation of the system (e.g., 10 or 110) over a course of a long period of time, it is typical that a predetermined volume of water flow is desired. For example, it may be desirable to move a volume of water equal to the volume within the pool. Such movement of water is typically referred to as a turnover. It may be desirable to move a volume of water equal to multiple turnovers within a specified time period (e.g., a day). Within an example in which the water operation includes a filter operation, the desired water movement (e.g., specific number of turnovers within one day) may be related to the necessity to maintain a desired water clarity.
Within yet another aspect of the present invention, the pumping system 10 may operate to have different constant flow rates during different time periods. Such different time periods may be sub-periods (e.g., specific hours) within an overall time period (e.g., a day) within which a specific number of water turnovers is desired. During some time periods a larger flow rate may be desired, and a lower flow rate may be desired at other time periods. Within the example of a swimming pool with a filter arrangement as part of the water operation, it may be desired to have a larger flow rate during pool-use time (e.g., daylight hours) to provide for increased water turnover and thus increased filtering of the water. Within the same swimming pool example, it may be desired to have a lower flow rate during non-use (e.g., nighttime hours).
Turning to one specific example, attention is directed to the top-level operation chart that is shown in
Briefly, the Vacuum run operation 206 is entered and utilized when a vacuum device is utilized within the pool 14. For example, such a vacuum device is typically connected to the pump 16 possibly through the filter arrangement 22, via a relatively long extent of hose and is moved about the pool 14 to clean the water at various locations and/or the surfaces of the pool at various locations. The vacuum device may be a manually moved device or may autonomously move.
Similarly, the manual run operation 208 is entered and utilized when it is desired to operate the pump outside of the other specified operations. The heater run operation 212 is for operation performed in the course of heating the fluid (e.g., water) pumped by the pumping system 10.
Turning to the filter mode 210, this is a typical operation performed in order to maintain water clarity within the pool 14. Moreover, the filter mode 210 is operated to obtain effective filtering of the pool while minimizing energy consumption. Specifically, the pump is operated to move water through the filter arrangement. It is to be appreciated that the various operations 204-212 can be initiated manually by a user, automatically by the means for operating 30, and/or even remotely by the various associated components, such as a heater or vacuum, as will be discussed further herein.
It should be appreciated that maintenance of a constant flow volume despite changes in pumping system 10, such as an increasing impediment caused by filter dirt accumulation, can require an increasing flow rate or flow pressure of water and result in an increasing motive force from the pump/motor. As such, one aspect of the present invention is to provide a means for operating the motor/pump to provide the increased motive force that provides the increased flow rate and/or pressure to maintain the constant water flow.
It is also be appreciated that operation of the pump motor/pump (e.g., motor speed) has a relationship to the flow rate and/or pressure of the water flow that is utilized to control flow rate and/or flow pressure via control of the pump. Thus, in order to provide an appropriate volumetric flow rate of water for the various operations 104-112, the motor 24 can be operated at various speeds. In one example, to provide an increased flow rate or flow pressure, the motor speed can be increased, and conversely, the motor speed can be decreased to provide a decreased flow rate or flow pressure.
Focusing on the aspect of minimal energy usage, within some know pool filtering applications, it is common to operate a known pump/filter arrangement for some portion (e.g., eight hours) of a day at effectively a very high speed to accomplish a desired level of pool cleaning. With the present invention, the system (e.g., 10 or 110) with the associated filter arrangement (e.g., 22 or 122) can be operated continuously (e.g., 24 hours a day, or some other amount of time) at an ever-changing minimum level to accomplish the desired level of pool cleaning. It is possible to achieve a very significant savings in energy usage with such a use of the present invention as compared to the known pump operation at the high speed. In one example, the cost savings would be in the range of 90% as compared to a known pump/filter arrangement.
Turning to one aspect that is provided by the present invention, the system can operate to maintain a constant flow of water within the fluid circuit. Maintenance of constant flow is useful in the example that includes a filter arrangement. Moreover, the ability to maintain a constant flow is useful when it is desirable to achieve a specific flow volume during a specific period of time. For example, it may be desirable to filter pool water and achieve a specific number of water turnovers within each day of operation to maintain a desired water clarity.
In an effort to minimize energy consumption, the pumping system 10, 110 can be configured to operate the variable speed motor 24, 124 at a minimum speed while still achieving a desired water flow during a time period (e.g., a desired number of turnovers per day). In one example, a user can provide the pumping system 10, 110 directly with a desired flow rate as determined by the user through calculation, look-up table, etc. However, this may require the user to have an increased understanding of the pool environment and its interaction with the pumping system 10, 110, and further requires modification of the flow rate whenever changes are made to the pool environment.
In another example, the controller 30, 130 can be configured to determine a target flow rate of the water based upon various values. As such, the pumping system 10 can include means for providing a target volume amount of water to be moved by the pumping system 10, 110, and means for providing a time period value for operation thereof. Either or both of the means for providing a target volume amount and a time period can include various input devices, including both local input devices, such as the keypad 40 of the user interface 31, 131, and/or remote input devices, such as input devices linked by a computer network or the like. In addition or alternatively, the controller 30, 130 can even include various methods of calculation, look-up table, graphs, curves, or the like for the target volume amount and/or the time period, such as to retrieve values from memory or the like.
Further, the target volume amount of water can be based upon the volume of the pool (e.g., gallons), or it can even be based upon both the volume of the pool and a number of turnovers desired to be performed within the time period. Thus, for example, where a pool has a volume of 17,000 gallons, the target volume amount could be equal to 17,000 gallons. However, where a user desires multiple turnovers, such as two turnovers, the target volume amount is equal to the volume of the pool multiplied by the number of turnovers (e.g., 17,000 gallons multiplied by 2 turnovers equals 34,000 gallons to be moved). Further, the time period can include various units of time, such as seconds, minutes, hours, days, weeks, months, years, etc. Thus, a user need only input a volume of the swimming poll, and may further input a desired number of turnovers.
Additionally, the pumping system 10, 110 can further include means for determining the target flow rate of water to be moved by the pump based upon the provided target volume amount and time period value. As stated above, the target flow rate (e.g., gallons per minute (gpm)) can be determined by calculation by dividing the target volume amount by the time period value. For example, the equation can be represented as follows: Flow rate=(Pool volume.times.Turnovers per day)/(Cycle 1 time+Cycle 2 time+Cycle 3 time+etc.).
As shown in chart of
Further still, after the target flow rate is determined, the pumping system 10, 110 can include means for controlling the motor 24, 124 to adjust the flow rate of water moved by the pump to the determined target flow rate. In one example, the means for controlling can include the controller 30, 130. As mentioned previously, various performance values of the pumping system 10, 110 are interrelated, and can be determined (e.g., calculated, provided via a look-up table, graph or curve, such as a constant flow curve or the like, etc.) based upon particular other performance characteristics of the pumping system 110, such as input power consumed, motor speed, flow rate and/or the flow pressure. In one example, the controller 30, 130 can be configured to determine (e.g., calculation, look-up table, etc.) a minimum motor speed for operating the motor 24, 124 based upon the determined target flow rate. In another example, the controller 30, 130 can be configured to incrementally increase the motor speed, beginning at a baseline value, such as the motor's slowest operating speed, until the pump 24, 124 achieves the target flow rate. As such, the pump 24, 124 can operate at the minimum speed required to maintain the target flow rate in a steady state condition.
It is to be appreciated that the maintenance of a constant flow volume (e.g., the target flow rate) despite changes in pumping system 10, 110, such as an increasing impediment caused by filter dirt accumulation, can require an increasing target flow rate or flow pressure of water, and can result in an increasing power consumption of the pump/motor. However, as discussed herein, the controller 30 can still be configured to maintain the motor speed in a state of minimal energy consumption.
Turning now to another aspect of the present invention, the pumping system 10, 110 can control operation of the pump based upon performance of a plurality of water operations. For example, the pumping system 10, 110 can perform a first water operation with at least one predetermined parameter. The first operation can be routine filtering and the parameter may be timing and or water volume movement (e.g., flow rate, pressure, gallons moved). The pump can also be operated to perform a second water operation, which can be anything else besides just routine filtering (e.g., cleaning, heating, etc.). However, in order to provide for energy conservation, the first operation (e.g., just filtering) can be controlled in response to performance of the second operation (e.g., running a cleaner).
The filtering function, as a free standing operation, is intended to maintain clarity of the pool water. However, it should be appreciated that the pump (e.g., 16 or 116) may also be utilized to operate other functions and devices such as a separate cleaner, a water slide, or the like. As shown in
Further, associated with such other functions and devices is a certain amount of water movement. The present invention, in accordance with one aspect, is based upon an appreciation that such other water movement may be considered as part of the overall desired water movement, cycles, turnover, filtering, etc. As such, water movement associated with such other functions and devices can be utilized as part of the overall water movement to achieve desired values within a specified time frame. Utilizing such water movement can allow for minimization of a purely filtering aspect to permit increased energy efficiency by avoiding unnecessary pump operation.
For example,
Turning now to
It should be appreciated that pump operation for all of these cycles, functions, and devices on an unchangeable schedule would be somewhat wasteful. As such, the present invention provides for a reduction of a routine filtration cycle (e.g., cycle 322) in response to occurrence of one or more secondary operations (e.g., cycle 332). As with the previously discussed cycle 302, the pumping system 10, 110 would normally move approximately 17,000 gallons if it is operated at a rate of 20 gallons per minute for 14 hours (e.g., 8:00 am-10:00 pm). However, because the secondary operation (e.g., cycle 332) requires a higher flow rate (e.g., 50 gpm versus 20 gpm), operation of the routine filtration cycle (e.g., cycle 322) can now be reduced. For example, if the routine filtration cycle 322 is operated at 20 gpm for 10 hours (e.g., 8:00 am to 6:00 pm), the pumping system will have moved approximately 12,000 gallons.
Next, if the secondary operation cycle 332 operates at 50 gpm for 1 hour (e.g., 6:00 pm to 7:00 pm), the pumping system 10, 110 will have moved approximately 3,000 gallons. Thus, by the end of the secondary cycle 332 (e.g., 7:00 pm) the pumping system 10, 110 will have cumulatively moved approximately 15,000 gallons. As such, the pumping system needs only move an additional 2,000 gallons. If the pumping system 10, 110 returns to the initial 20 gpm flow rate, then it need only to run for approximately an additional 1.5 hours (e.g., 8:30 pm) instead of the originally scheduled 3 additional hours (e.g., originally scheduled for 10:00 pm end time, see
Accordingly, the pumping system 10, 110 can alter operation motor 24, 124 based upon the operation of multiple cycles 322, 332 to conserve energy and increase efficiency of the pumping system 10, 110 (e.g., a power save mode). It is to be appreciated that the pumping system 10, 110 can alter operation of the motor by further slowing the motor speed, such as in situations where at least some water flow is required to be maintained within the pool, or can even stop operation of the motor 24, 124 to eliminate further power consumption.
Reducing power consumption of the pumping system 10, 110 as described above can be accomplished in various manners. In one example, the pumping system 10, 110 can include means for providing a target volume amount of water to be moved by the pump 24, 124, and means for providing an operational time period for the pump 24, 124 (e.g., a time period during which the pump 24, 124 is in an operational state). As stated previously, either or both of the means for providing the target volume amount and the operational time period can include various local or remote input devices, and/or even calculation, charts, look-up tables, etc.
The pumping system 10, 110 can further include means for determining a volume of water moved by the pump 24, 124 during the operational time period. The means for determining a volume of water moved can include a sensor 50, 150, such as a flow meter or the like for measuring the volume of water moved by the pump 24, 124. The controller 30, 130 can then use that information to determine a cumulative volume of water flow through the pool. In addition or alternatively, the controller 30, 130 can indirectly determine a volume of water moved through a “sensorless” analysis of one or more performance values 146 of the pumping system 10, 110 during operation thereof. For example, as previously discussed, it is an understanding that operation of the pump motor/pump (e.g., power consumption, motor speed, etc.) has a relationship to the flow rate and/or pressure of the water flow (e.g., flow, pressure) that can be utilized to determine particular operational values (e.g., through calculation, charts, look-up table, etc.).
The pumping system 10, 110 can further include means for altering the operational time period based upon the volume of water moved during the operational time period. As discussed above, the controller 30, 130 can be configured to determine the cumulative volume of water flow through the pool. It is to be appreciated that the determination of cumulative water flow can be performed at various time intervals, randomly, or can even be performed in real time. As such, the controller 30, 130 can be configured to monitor the cumulative volume of water being moved by the pumping system 10, 110 during the operational time period (e.g., keep a running total or the like).
Thus, as illustrated above with the discussion associated with
In another example, the operational time period can be bounded by an end time, and/or can even be bounded by a start time and an end time. Thus, the controller 30, 130 can further comprise means for determining an end time (e.g., such as end time 326) based upon the operational time period. For example, as shown in
Accordingly, in an effort to conserve energy consumption of the motor 24, 124, the pumping system 10, 110 can further include means for altering operation of the motor 24, 124 based upon the operational time period. For example, the controller 30, 130 can be configured to reduce (e.g., operate at a slower speed), or even stop, operation of the motor 24, 124 based upon the operational time period. Thus, when the operational time period in real time exceeds the end time 326, the controller 30, 130 can reduce or stop operation of the motor 24, 124 to conserve energy consumption thereof. Thus, as illustrated in
It is further to be appreciated that the various examples discussed herein have included only two cycles, and that the addition of a second cycle is associated with a greater water flow that thereby necessitates the overall operational time period of the motor 24, 124 to be reduced. However, the present invention can include various numbers of operational cycles, each cycle having various operational time periods and/or various water flow rates. In addition or alternatively, the present invention can operate in a dynamic manner to accommodate the addition or removal of various operational cycles at various times, even during a current operational cycle.
In addition or alternatively, the present invention can further be adapted to increase an operational time period of the pump 24, 124 in the event that one or more additional operational cycles include a lower flow rate. Such an increase in the operational time period can be accomplished in a similar fashion to that discussed above, though from a point of view of a total volume flow deficiency. For example, where a primary filtering cycle includes a steady state flow rate of 20 gpm, and a secondary cycle includes a flow rate of only 10 gpm, the controller 30, 130 can be configured to alter the operational time period to be longer to thereby make up for a deficiency in overall water volume moved. In addition or alternatively, the controller 30, 130 could also be configured to increase the flow rate of the primary cycle to make up for the water volume deficiency without altering the operational time period (e.g., increase the flow rate to 30 gpm without changing the end time). As discussed herein, the controller 30, 130 can choose among the various options based upon various considerations, such as minimizing power consumption or time-of-day operation.
Reducing power consumption of the pumping system 10, 110 as described above can also be accomplished in various other manners. Thus, in another example, the pumping system 10, 110 can further include means for determining a volume of water moved by the pump 24, 124, such as through a sensor 50, 150 (e.g., flow meter or the like), or even through a “sensorless” method implemented with the controller 30, 130 as discussed previously herein. The volume of water moved can include water moved from one or more operational cycles (e.g., see
Additionally, the pumping system 10, 110 can further include means for altering operation of the motor 24, 124 when the volume of water moved by the pump 12, 112 exceeds a target volume amount. As discussed above, the target volume amount of water can be provided in various manners, including input by a user (e.g., through a local or remote user interface 31, 131) and/or determination by the controller 30, 130.
Thus, for example, where the target volume amount is 17,000 gallons, the controller 30, 130 can monitor the total volume of water moved by the pumping system 10, 110, and can alter operation of the motor 24, 124 when the total volume of water moved exceeds 17,000 gallons, regardless of a time schedule. It is to be appreciated that the pumping system 10, 110 can alter operation of the motor by slowing the motor speed, such as in situations where at least some water flow is required to be maintained within the pool, or can even stop operation of the motor 24, 124 to eliminate further power consumption.
In addition to monitoring the volume flow of water moved by the pump 24, 124, the controller 30, 130 can also monitor the volume flow of water moved within a time period, such as the operational time period discussed above. Thus, for example, where the operation time period is determined to be fourteen hours, the controller 30, 130 can monitor the volume flow rate of water moved only during the fourteen hours. As such, the controller 30, 130 can then alter operation of the motor 24, 124 depending upon whether the cumulative volume of water moved (e.g., including water flow from various operational cycles) exceeds the target volume amount during that fourteen hour time period. It is to be appreciated that, similar to the above description, the controller 30, 130 can also be adapted to increase the flow rate of water moved by the pump 24, 124 to make up for a water volume deficiency (e.g., the total volume of water does not exceed the target volume of water by the end of the time period). However, it is to be appreciated that a time period is not required, and the total volume of water moved can be determined independently of a time period.
Turning now to yet another aspect of the present invention, the pumping system 10, 110 can further be configured to determine an optimized flow rate value based upon various variables. The determination of an optimized flow rate can be performed within the pumping system 10, 110, such as within the controller 30, 130. However, it is to be appreciated that the determination of an optimized flow rate can even be performed remotely, such as on a computer or the like that may or may not be operatively connected to the pumping system 10, 110. For example, the determination of an optimized flow rate value can be performed on a personal computer or the like, and can even take the form of a computer program or algorithm to aid a user reducing power consumption of the pump 24, 124 for a specific application (e.g., a specific swimming pool).
For the sake of brevity, the following example will include a discussion of the controller 30, 130, and the various elements can be implemented in a computer program, algorithm, or the like. In determining an optimized flow rate, the pumping system 10, 110 can include means for providing a range of time period values, such as a range of seconds, minutes, hours, days, weeks, months, years, etc. For example, as shown on chart 400 of
Further, the pumping system 10, 110 can include means for determining a range of flow rate values of water to be moved by the pump 24, 124 based upon a target volume of water and the range of time period values. As discussed above, the target volume of water to be moved by the pump 24, 124 can be provided by a user interface 31, 131, and/or determined by calculation, look-up table, chart, etc. In one example, a user can provide the target volume of water through the keypad 40. Thus, a particular flow rate value (e.g., gallons per minute) can be determined for each time value within the range of time values by dividing the target volume of water by each time value. For example, where the target volume of water is equal to 17,000 gallons, and where the range of time values includes 10 hours, 15 hours, and 20 hours, the associated range of flow rates can be calculate to be approximately 28 gpm, 19 gpm, and 14 gpm.
Further still, the pumping system 10, 110 can include means for determining a range of motor speed values (e.g., RPM) based upon the range of determined flow rate values. Each motor speed value can be associated with a flow rate value. In one example, the controller 30, 130 can determine each motor speed value through calculation, look-up table, chart, etc. As discussed previously, a relationship can be established between the various operating characteristics of the pumping system 10, 110, such as motor speed, power consumption, flow rate, flow pressure, etc. Thus, for example, a particular motor speed can be determined from operation of the motor 24, 124 at a particular flow rate and at a particular flow pressure. As such, a range of motor speed values can be determined and associated with each of the flow rate values.
The pumping system 10, 110 can further include means for determining a range of power consumption values (e.g., instantaneous power in Watts or even power over time in kWh) of the motor 24, 124 based upon the determined motor speed values. Each power consumption value can be associated with a motor speed value. As before, a relationship can be established between the various operating characteristics of the pumping system 10, 110, such as motor speed, power consumption, flow rate, flow pressure, etc. Thus, for example, a particular power consumption value can be determined from operation of the motor 24, 124 at a particular motor speed and flow rate. As such, a range of power consumption values can be determined and associated with each of the motor speed values.
The pumping system 10, 110 can further include means for determining an optimized flow rate value that is associated with the lowest power consumption value of the motor 24, 124. For example, the optimized flow rate value can be the flow rate value of the range of flow rate values that is associated, through the intermediate values discussed above, with the lowest power consumption value of the range of power consumption values. In another example, as shown in the chart 400 of
The chart 400 includes operational data for three pool sizes, such as 17,000 gallon pool 404, a 30,000 gallon pool 406, and a 50,000 gallon pool 408, though various size pools can be similarly shown, and only the pool size associated with a user's particular swimming pool is required. As illustrated, each set of operational data 404, 406, 408 includes minimum and maximum values (e.g., minimum and maximum power consumption values). Thus, by determining a minimum value of the power consumption for a particular pool size, an optimal time period (e.g., hours per day for operation of the pump) can be determined, and subsequently an optimal flow rate can be determined. However, as shown, the minimum power consumption value for the various pool sizes 404, 406, 408 can occur at different values. For example, regarding the 17,000 gallon pool 404, the minimum power consumption value can occur with a relatively lesser operational time (e.g., operating the pump for less hours per day). However, it is to be appreciated that as the pool volume is increased, operation of the pump 24, 124 for a lesser amount of time can generally require a higher flow rate, which can generally require a higher motor speed and higher power consumption. Conversely, operating the motor 24, 124 at a slower speed for a longer period of time can result in a relatively lower power consumption. Thus, regarding the 50,000 gallon pool 408, the minimum power consumption value can occur with a relatively greater operational time, such as around 16 or 17 hours per day.
The minimum value of the power consumption can be determined in various manners. In one example, the operational data can be arranged in tables or the like, and the minimum data point located therein. In another example, the chart 400 can include a mathematical equation 410, 412, 414 adapted to approximately fit to the operational data of each pool 404, 406, 408, respectively. The approximate mathematical equation can have various forms, such as a linear, polynomial, and/or exponential equation, and can be determined by various known methods, such as a regression technique or the like. The controller 30, 130 can determine the minimum power consumption value by finding the lowest value of the mathematical equation, which can be performed by various known techniques. Because the fit line can be represented by a continuous equation, the values can include whole numbers (e.g., 20 gpm for 14 hours) or can even include decimals (e.g., 24.5 gpm for 12.7 hours). However, it is to be appreciated that because the mathematical equation is an approximation of the operational data 404, 406, 408, various other factors, such as correction factors or the like, may be applied to facilitate determination of the minimum value.
Further still, it is to be appreciated that variations in cycle times and/or determinations of flow rates can be based upon the varying cost of electricity over time. For example, in some geographical regions, energy cost is relatively higher during the daytime hours, and relatively lower during the nighttime hours. Thus, a determined flow rate and operational schedule may include a lower flow rate operable for a longer period of time during the nighttime hours to further reduce a user's energy costs.
Thus, once the controller 30, 130 determines an optimal flow rate (or a user inputs an optimal flow rate based upon a remote determination made using a computer program running on a personal computer or the like), the pumping system 10, 110 can further include means for controlling the motor 24, 124 to adjust the flow rate of water moved by the pump 12, 112 to the optimized flow rate value. The controller 30, 130 can operate to maintain that optimized flow rate value as discussed previously herein, and/or can even adjust the flow rate among various operational flow rates. Additionally, the controller 30, 130 can further monitor an operational time period and/or a total volume of water moved by the system, as discussed herein, and can alter operation of the motor accordingly.
It is to be appreciated that the physical appearance of the components of the system (e.g., 10 or 110) may vary. As some examples of the components, attention is directed to
