Various exemplary embodiments relate to a liquid-collecting system, a liquid drainage system, and a method for use
In principle, there are devices that regularly and/or continuously dispense liquid (also generally referred to as a liquid source), the operation of which within buildings requires a separate disposal infrastructure for disposing of the liquid. For example, refrigeration units in supermarkets can produce condensed water that is drained off by means of the disposal infrastructure. Traditionally, the disposal infrastructure includes a pipe system buried in the ground, by means of which the liquid is drained.
According to various embodiments, a liquid-collecting arrangement, a liquid drainage system, and methods for use are provided that simplify the disposal infrastructure so that it is less complex and thus less expensive, easier to assemble, and serves a wider range of applications.
Clearly, the liquid-collecting arrangement provided herein means that an existing disposal infrastructure can be retrofitted or converted more easily and the disposal infrastructure can be reconfigured more easily or it is possible to react to a change in the requirements for the disposal infrastructure with less effort. For example, the liquid-collecting arrangement can make it easier to construct a disposal infrastructure if there is no pipe system in the around, if the pipe system does not match the positions of the liquid sources (for example refrigeration units), or if the premises are to be changed more frequently.
For example, supermarkets and other shops (retail) are moving towards renting their premises. However, if these are not pre-equipped with a matching disposal infrastructure, an expensive modification would have to be carried out, which can be averted by means of the liquid-collecting arrangement.
As explained above, the liquid-collecting arrangement makes it possible to simplify the disposal infrastructure. For example, the liquid-collecting arrangement can make it possible to reduce the liquid-draining pipelines per liquid source (for example refrigeration unit). For example, the liquid-collecting arrangement can make it possible to dispense with buried collecting containers and their complex cleaning. For example, the liquid-collecting arrangement can make it possible to require fewer assembly steps per liquid source.
Clearly, the liquid-collecting arrangement has a large number of connection options, so that it is easier to assemble and/or can serve a larger or variable range of applications. The liquid-collecting arrangement has multiple liquid feeds on each of both sides, so that it can be connected to more liquid sources or to variably positioned liquid sources without increasing the assembly effort. For example, an additional liquid source can be connected to the existing liquid-collecting arrangement with less effort, or this liquid source can also be disconnected from it again if this is desired. This means that liquid sources can be exchanged more easily or the number of them can be changed without much effort.
In the figures
In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which specific embodiments in which the invention can be implemented are shown for illustration. In this regard, directional terminology such as “above”, “below”, “front”, “back”, “front”, “rear”, etc. is used with reference to the orientation of the described figure(s). Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way restrictive. It is understood that other embodiments can be utilized and structural or logical changes can be made without departing from the scope of the present invention. It is understood that the features of the various exemplary embodiments described herein can be combined with one another unless specifically stated otherwise. The following detailed description is therefore not to be interpreted in a restrictive sense, and the scope of protection of the present invention is defined by the appended claims.
Within the scope of this description, the terms “connected”, “attached”, and “coupled” are used to describe both a direct and an indirect connection (for example electrically conductive and/or fluidic connection), a direct or indirect attachment, and a direct or indirect coupling. In the figures, identical or similar elements are provided with identical reference signs, insofar as this is appropriate.
According to various embodiments, the term “coupled” or “coupling” can be understood in the sense of a (e.g., mechanical, hydrostatic, thermal, and/or electrical), for example direct or indirect, connection and/or interaction. For example, multiple elements can be coupled to one another along an interaction chain, along which the interaction can be exchanged, for example a fluid (then also referred to as fluidically coupled or hydrostatically coupled). For example, two elements coupled to one another can exchange an interaction with one another, e.g., a mechanical, hydrostatic, thermal, and/or electrical interaction. Multiple components of a hydrostatic composite (e.g., fittings, valves, pumps, lines, containers, hoses, etc.) can be coupled to one another in order to exchange a fluid. Their coupling to one another can include that they are fluidically coupled to one another. According to various embodiments, “coupled” can be understood in the sense of a mechanical (for example physical) coupling, for example by means of a direct physical contact.
In principle, a line can include a hollow body that is open on both sides. The line can, for example, be configured rigidly (for example including a pipe) or configured flexibly (for example including a hose). A rigid line (for example a pipe) can, for example, be so rigid that it can bridge a distance of more than 5 times (for example 10 times or 20 times) the circumference of the line in a freely cantilevered manner. A flexible line (for example a hose) can, for example, be so flexible that it can be reversibly curved (for example under the influence of its own weight), for example along an arc of a circle whose diameter is less than 10 times (for example 5 times) the circumference of the line.
Controlling can be understood as intentional influencing of a present state, for example the state of an entity (for example a device, a system, or a process). The present state of the entity (also referred to as the actual state) can be changed according to a specification (also referred to as the target state). Regulation can be understood as controlling, wherein a state change due to disturbances is also counteracted. Clearly, the controller can have a forward-directed controlled system and thus can clearly implement a sequence control which converts an input variable (for example the specification) into an output variable. However, the controlled system can also be part of a control loop, so that a regulation is implemented. In contrast to the purely forward-oriented sequence control, regulation has a continuous influence of the output variable on the input variable, which is caused by the control loop (also referred to as feedback). In other words, regulation can be used alternatively or additionally to the control, or regulation can take place alternatively or additionally to the control. In a control loop, the measuring element (also referred to as a sensor), control element (also referred to as a control device), and actuator form an interaction chain of the control loop whose end points are connected to one another by the entity to be influenced to form the control loop.
The term “actuator” can be understood as a physical component that is configured to influence the actual state in that an actuation of the actuator takes place. The actuator can convert instructions of both by the control device (the so-called actuation) into mechanical movements or changes in physical variables, such as pressure, force, or flow rate. The actuator, for example an electromechanical converter, can be configured, for example, in response to actuation to convert electrical energy into mechanical energy (for example by movement), to eliminate or establish a fluidic connection, etc. The actuator can include a drive device (also referred to as an actuator). Examples of an actuator include: an electric motor, an automatic valve (or other fluid-mechanical switch), a pump, or the like. Examples of the drive device include: a motor, a magnetic drive, a piezoelectric drive, a reciprocating piston, or the like. The motor or the drive device can be, for example, a linear motor or a rotary motor. The linear motor can be configured, for example, to generate and output a linear movement. The drive device (for example the linear motor) can include a magnetic coil (for example a cylinder coil), for example.
The term “control device” can be understood as any type of logic-implementing entity, which can include, for example, a processor (and, for example, corresponding circuitry), which can, for example, execute software stored in a storage medium, in firmware, or in a combination thereof, and can output instructions based thereon. The control device (for example implementing a control loop) can be configured to implement one or more than one of the processes described herein. The control device can include, for example, a programmable logic controller (PLC) or can be formed therefrom.
A waste liquid is referred to herein as an exemplary fluid. It can be understood that what has been described for the waste liquid can apply by analogy to any other (for example condensed) fluid (for example including or consisting of a liquid). The waste liquid can include or consist of an organic liquid, for example. The waste liquid can include or consist of an inorganic liquid, for example. Examples of the waste liquid include: waste water, condensed water, coolant liquid, oil, etc. Waste water can clearly include contaminated water, for example including suspended matter or other solid matter, including a liquid other than water, including dissolved components. Condensed water is water that condenses on a cool surface of objects as soon as water-containing air or gas is cooled below the dew point there. If the moisture condenses from water-containing air, the condensed water can also contain condensable air impurities. What has been described with regard to the waste liquid can, for example, apply by analogy to any direct vacuum drainage from one or more than one device that produces or at least has a liquid to be discharged (also referred to as a liquid source).
According to various embodiments, the exchange (for example transport) of a fluid (for example a liquid, for example the waste liquid) is excited or effectuated by means of a pressure differential (also referred to as extraction). Due to the extraction, the fluid can be withdrawn efficiently and against the force of gravity and/or over a longer distance, for example remotely. For example, the pump system used for extraction can be arranged at a greater distance from the location of the waste liquid-collecting arrangement.
Extraction can include subjecting the fluid to the pressure differential (for example, between a negative pressure and atmospheric air pressure). The pressure differential can be, for example, greater than approximately 0.1 bar, for example approximately 0.25 bar, for example approximately 0.5 bar, for example approximately 0.75 bar, for example approximately 0.9 bar. The application of the pressure differential to the fluid can include, for example, subjecting the fluid to the negative pressure (for example, a vacuum). The negative pressure can be less than the atmospheric air pressure. The negative pressure can be generated, for example, by means of a pump system. The negative pressure can be less than approximately 0.8 bar, for example approximately 0.7 bar, for example approximately 0.6 bar. The vacuum can be less than approximately 0.3 bar, for example approximately 0.2 bar, for example approximately 0.1 bar. The fluid can be exposed to atmospheric air pressure by means of a so-called ventilation opening. The extraction can include transporting the fluid toward the negative pressure and away from the atmospheric air pressure.
Reference is made here to various components (e.g., fittings, pumps, lines, containers, hoses, etc.) of a hydrostatic compound, which can optionally be configured to be suitable for negative pressure (then also referred to as negative pressure component). A negative pressure component (e.g., negative pressure line, negative pressure hose, negative pressure connection, negative pressure container, etc.) can clearly be set up to be negative pressure-stable (for example vacuum-stable), i.e. it can withstand a negative pressure in the interior during external application of the atmospheric air pressure (also referred to as pressure-stable), for example essentially without deformation and/or while maintaining its fluid-conducting capabilities, and/or separate them from each other airtight. This ensures that the negative pressure component is still fluid-conducting when a negative pressure is applied thereto, so that extraction can take place through it. A negative pressure fitting can include a seal, for example.
According to various embodiments, a negative hose (for example vacuum hose), a negative pressure pipe, or a negative pressure line (for example vacuum line) can be designed to be dimensionally stable in such a way that it withstands the effects of atmospheric air pressure in the pumped-out state. A pump system (including at least one vacuum pump and/or one liquid pump) can make it possible to pump part of the gas out of the interior of the waste liquid-collecting arrangement, for example out of its collecting space.
Reference is also made herein to fittings (for example, feed fitting or outlet fitting). A fitting can be configured to be coupled to another component (for example, to form a hydrostatic composite), for example, to another fitting and/or to a device that dispenses and/or receives a fluid. For this purpose, the connection can include one or more than one form-fitting contour. Examples of a form-fitting contour include: eyelet, thread, through-opening, depression or latching lug (for example of a latching closure), longitudinal slot (for example of a bayonet closure), projection (for example of the bayonet closure), etc. For example, the fitting can include a flange or be formed therefrom.
According to various embodiments, a possibility for connecting cooling/freezing units to a vacuum drainage system and a possibility for discharge condensate from the cooling/freezing units is provided. The connection is established by means of a collecting container having one or more inlets and outlets and flexible hoses, wherein one end is connected to a condensate outlet in the cooling/freezing units and the other end is connected to the collecting container. The condensate can flow freely from the refrigerating/freezing units via hoses to the collecting container. When the collecting container is full, a level switch in the collecting container gives a signal to drain the collecting container and to extract the condensate, for example from the hoses. Then the process repeats itself.
The advantage of this configuration is, among other things, that multiple refrigerating/freezing units (for example up to 8 units) can be connected to one interface/lifting unit, which minimizes costs and is less visually disturbing (for example by reducing the number of vertical lifting pipes). This is particularly important in large supermarkets. Other advantages include that the system is closed, emits less odor, is self-cleaning, flexible, and easy to install, can provide different length of hoses, can enable variable position of the collecting container.
Optionally, the at least one extraction fitting 104 (also referred to as an outlet fitting) can include multiple extraction fittings (not shown, also designated as left extraction fitting 104 and right extraction fitting 104), which are arranged, for example, on opposite sides of the container 102 and/or extend away from one another. This facilitates the assembly of the waste liquid-collecting arrangement 151. In the following, reference is made to an extraction fitting 104 as an example, which is used to extract the waste liquid. In the case of multiple extraction fittings, example, each extraction fitting of the waste liquid-collecting arrangement 151 that is different from the extraction fitting 104 and that is not to be used for suction (then also referred to as an inactive extraction fitting) can be reversibly closed.
The waste liquid collecting arrangement 151, for example the container housing, furthermore includes a sensor opening 106 which is connected to the collecting space 102h, for example opens therein. Optionally, a liquid sensor can be or become arranged in the sensor opening 106, as will be described later in more detail. The liquid sensor can be configured to detect the waste liquid in the collecting space 102h. Optionally, an inactive extraction fitting (if present) or the corresponding opening in the container 102 can be used as the sensor opening 106.
The waste liquid-collecting arrangement 151 also includes a large number of waste liquid feeds 108, 118, for example four or more waste liquid feeds. The large number of waste liquid feeds includes multiple first waste liquid feeds 108, which include a first waste liquid feed 108a, an additional first waste liquid feed 108b, and optionally also one or more than one additional first waste liquid feed (not shown). The large number of waste liquid feeds furthermore includes multiple second waste liquid feeds 118, which include a second waste liquid feed 108a and an additional second waste liquid feed 108b, and optionally also one or more than one additional second waste liquid feed (not shown). For example, a number of waste liquid feeds per side 101a, 101b can be more than 2, more than 3, or more than 4.
The multiple first waste liquid feeds 108 and the multiple second waste liquid feeds 118 can, for example, open into the collecting space 102h on opposite sides (also referred to as first side 101a and second side 102b) of the container 102 (for example through its container housing).
The container 102 (for example its container body) can include multiple first openings 102o (also referred to as first container openings or inlet openings) on the first side 101a (also referred to as the first lateral side), of which each first opening 102o is coupled to or receives a waste liquid feed of the multiple waste liquid feeds (for example, of the multiple first waste liquid feeds 108). The openings 102o can be provided, for example, by means of corresponding fittings (also referred to as inlet nozzles or inlet fittings) of the container 102. For example, each inlet fitting can include a protruding pipe stub.
The container 102 (for example its container housing) can include multiple second openings 112o (also referred to as second container openings or inlet openings) on the second side 101b (also referred to as the second lateral side), of which each second opening 112o is coupled to or receives a waste liquid feed of the multiple waste liquid feeds (for example, of the multiple second waste liquid feeds 118).
This two-sided opening of waste liquid feeds into the collecting space 102h facilitates the connection of the waste liquid collecting arrangement 151 to devices that discharge waste liquid (also referred to as a source for waste liquid or as a liquid source in short). Clearly, due to the two-sided opening, less complex fluid guidance is required, the transport routes can be shorter, and the assembly can be facilitated.
Reference is made herein by way of example, and in particular below by way of example, to one waste liquid feed of the plurality of waste liquid feeds (for example of the plurality of first waste liquid feeds 108 and/or of the plurality of second waste liquid feeds 118). It can be understood that what is described for the exemplary waste liquid feed applies by analogy to more than one waste liquid feed of the plurality of waste liquid feeds (for example of the multiple first waste liquid feeds 108 and/or of the multiple second waste liquid feeds 118), for example for each waste liquid feed of the multiple first waste liquid feeds 108 and/or of the multiple second waste liquid feeds 118.
The container 102 can include, for example, a lower side 801b (cf.
For example, a height (dimension from the upper side 801a to the lower side 801b) of the container 102 can be less than approximately 0.4 m (meters), for example approximately 0.3 m, for example approximately 0.2 m, for example approximately 0.1 m, for example approximately 0.05 m. This achieves the flattest possible construction of the container 102 so that it can be more easily placed under a source for waste liquid. Alternatively or additionally, the height of the container 102 can be less than a width of the container 102 (dimension from the first side 101a to the second side 101b) and/or a length of the container 102.
For example, a volume of the collecting space 102h can be in a range from approximately 0.5 L (liters) to approximately 15 liters (dm3) or in a range from approximately 0.01 L (liters) to approximately 20 L, for example in a range of approximately 0.1 L to approximately 10 L. Alternatively or additionally, the volume of the collecting space 102h can be greater than approximately 0.5 L, for example, approximately 1 L, for example, approximately 2 L, for example, approximately 5 L. Alternatively or additionally, the volume of the collecting space 102h can be less than approximately 100 L, for example than approximately 50 L, for example approximately 20 L, for example approximately 10 L.
The waste liquid-collecting arrangement 151 can be or become arranged in a building, for example.
The container 102 (for example its container housing) can include a third opening 104o (for example laterally or on the upper side), which is coupled to the extraction fitting 104 or receives it. The mouth of the extraction fitting 104 can, for example, have the same height position as the bottom 102b of the container 102, which delimits the collecting space 102h towards the lower side 801b. This promotes the extraction of the waste liquid from the container 102. For example, the extraction fitting 104 can open out laterally (for example from direction 103) into the collecting space 102h. For example, the extraction fitting 104 can extend through the third opening 104o from above and into the collecting space 102h toward the bottom of the container 102.
The hose 202 can include a flexible elongate hollow body, for example having a round cross section. In contrast to an inflexible line (for example a pipe), the hose can be deformed with little force and/or reversibly, for example even under the effect of its own weight. For example, the hose can adapt itself to the contour of an underlying surface on which the hose is arranged under the action of gravity alone. In order to provide the flexibility, the hose can be made of a suitable material or can be or become provided in a suitable shape. The hose 202 can, for example, include or consist of a polymer (for example an elastomer, for example rubber). The hose 202 can, for example, include or consist of fibers, for example a fabric or as a component of a composite material. For example, the hose 202 can include or consist of metal, for example, providing folds, corrugations, a fabric, and/or windings of the hose. Examples of the hose 202 include: a corrugated hose, a metal bellows, a fabric hose, a wound hose, a plastic hose.
The hose 202 further facilitates the connection of the waste liquid-collecting arrangement 151 to liquid sources. Clearly, due to the flexible property of the hose 202, less complex fluid guidance is required, the transport routes can be shorter, and the assembly can be facilitated.
The hose 202 can, for example, have a length (distance of the fluid-conducting connection between hose inlet and hose outlet) which is approximately 0.5 m (meters) or is greater than approximately 0.5 m (meters), for example approximately 1 m or greater than approximately 1 m, for example approximately 2 m or greater than approximately 2 m, for example approximately 3 m or greater than approximately 3 m, for example approximately 4 m or greater than approximately 4 m, for example approximately 5 m or greater than approximately 5 m, for example approximately 6 m or greater than approximately 6 m, for example approximately 7 m or greater than approximately 7 m. The longer the hose, the easier the assembly can be and the more variable the operable range of applications can be.
The feed fitting 302 further facilitates the connection of the waste liquid-collecting arrangement 151 to a liquid source. Clearly, a prefabricated and mutually compatible configuration can be provided, so that fewer assembly steps are necessary.
For example, the feed fitting 302 can include or be formed from a flange. The flange is a particularly easy to assemble and universal fitting type.
The valve 502 can be configured to be manually actuatable, for example. For this purpose, the valve 502 can include a manual actuating device, the actuation of which causes the valve to open or close. Examples of the manual actuating device include: a manual lever or a manual wheel.
The valve 502 facilitates the assembly and/or conversion of the waste liquid-collecting arrangement 151 even further. Clearly, the valve 502 can be closed when the corresponding waste liquid feed is not required, for example is blind, or when the fluid-conducting connection of a connected liquid source to the collecting space 102h is to be canceled (also referred to as disconnection or separation). This facilitates, for example, reacting to different or variable assembly situations.
The pressure compensation fitting 704 ensures that the collecting space 102h can receive gas (for example air) from the outside when the waste liquid is withdrawn from it (for example is extracted). Similarly, the collecting space 102h can release gas (for example, air) when receiving waste liquid or being heated. This facilitates the operation of the waste liquid-collecting arrangement 151.
Optionally, an inactive extraction fitting (if present) or the corresponding opening in the container 102 can be used as the pressure compensation fitting 704. This reduces the complexity of the waste liquid-collecting arrangement 151.
For example, the inlet opening 802o can have a greater height position relative to a zero level than the reference. The zero level is understood to mean an area to which the height position zero is assigned, for example according to the so-called “European Vertical Reference System” (EVRS). In the following, the more easily understood device-specific zero level, which corresponds to the height position of the reference, is used to indicate the height position. However, what has been described can also apply to another zero level, for example the geodetic zero level (for example sea level height, normal height zero, or Vienna zero).
For example, the height position of the inlet opening 802o (for example, measured along the direction of gravity) can be greater than an assembly value. The assembly value represents the possible assembly situation. The assembly value can be, for example, approximately 0.5 m or greater than approximately 0.5 m (meters), for example approximately 1 m or greater than approximately 1 m, for example approximately 2 m or greater than approximately 2 m, for example approximately 3 m or greater than approximately 3 m, for example approximately 4 m or greater than approximately 4 m. Accordingly, the down pipe can have a length that is greater than the assembly value. The direction of gravity can be opposite to direction 105.
The sensor 902 is configured to detect the waste liquid in the collecting space 102h (also referred to as liquid sensor 902). A sensor (also referred to as a detector) can be understood herein as a transducer that is configured to qualitatively or quantitatively detect a property of its environment corresponding to the sensor type, for example a physical or chemical property and/or a material composition. The measured variable is the physical variable to which the measurement by means of the sensor applies. Depending on the complexity of the environment of the sensor to be measured, the sensor can be configured to only be able to distinguish between discrete (for example two) states of the measured variable (also referred to as a measuring switch), for example to be able to distinguish between more than two states of the measured variable, or to quantitatively detect the measured variable. The measuring switch (as part of a sensor also referred to as a switch for short) can only distinguish, for example, whether the measured variable meets a criterion (for example exceeds or falls below a threshold value) or does not meet the criterion. An example of a measuring switch is a capacitive liquid sensor that is configured to detect whether a fill level as a measured variable has reached the location of the sensor or not, for example by detecting whether its capacitance is changed due to contact with the waste liquid or not. An additional example of a measuring switch is a float switch that switches when a float exceeds a certain position. An example of a quantitatively detected measured variable is, for example, a continuously recorded fill level (also referred to as a fill level sensor), which is detected, for example, by means of radiation (radar, sound, or light). The liquid sensor can be configured, for example, as a fill level sensor (also referred to as a level sensor).
The liquid sensor 902 can extend into the collecting space 102h, for example through the sensor opening 106. Alternatively or additionally, the liquid sensor 902 can be fluidically connected to the collection chamber 102h, for example by means of the sensor opening 106.
The liquid sensor 902 can be part of a measurement chain which includes a corresponding infrastructure (for example including a processor, storage medium, and/or bus system or the like). The measurement chain can be configured to control the corresponding sensor (e.g., water sensor, pressure sensor, and/or actuation sensor), to process its detected measured variable as an input variable and, based thereon, to provide an electrical signal (also referred to as a sensor signal) as an output variable, which indicates the state of the input variable for the represented time of detection. The measurement chain can be or become implemented by means of the sensor circuit 904.
The sensor circuit 904 is configured to detect the waste liquid in the cavity by means of the liquid sensor 902, for example its fill level (also referred to as level) and/or at least its presence at the location of the liquid sensor 902. The sensor circuit 904 is furthermore configured to output the sensor signal 9040 based on a result of detecting the waste liquid in the cavity 102h. The result of the detection can have, for example, the actual state of the waste liquid in the collecting space 102h as a measured variable, for example its level and/or presence (for example absence and/or presence).
The sensor signal 904o can be an analog signal, for example. The sensor signal 904o can be a digital sensor signal, for example. The digital sensor signal can include a message, for example, which is formed, for example, in accordance with a network communication protocol (for example a fieldbus communication protocol). The message can, for example, include a specification about the actual state of the waste liquid in the cavity 102h. However, in a simpler implementation, the digital sensor signal can also assume only two discrete logical states, one logical state of which indicating that the waste liquid is touching the liquid sensor 902 and the other logical state indicating that the waste liquid is at a distance from the liquid sensor 902.
The control device 1002 can be configured to actuate the drive device 1004 (for example by means of a message according to a network communication protocol, for example a fieldbus communication protocol). For this purpose, the control device 1002 can output a control signal 10020 based on the sensor signal or based on the result of detecting the waste liquid in the cavity 102h (also referred to as liquid detection).
The control signal 1002o can be an analog signal, for example. The control signal 1002o can be a digital sensor signal, for example. The digital control signal 1002o can include a message, for example, which is formed, for example, in accordance with a network communication protocol, for example a fieldbus communication protocol. The message can include a specification on the target state of drive device 1004, for example. In a simpler implementation, however, the digital sensor signal can also assume only two discrete logical states, of which one logical state indicates a first target state of the drive device 1004 and the other logical state indicates a second target state of the drive device 1004. Alternatively, the message can include corresponding instructions for the drive device 1004.
The extraction can be triggered (initiated) by the control device 1002 itself (for example autonomously), for example in response to the result of the liquid detection meeting a criterion (also referred to as a triggering criterion).
Optionally, the container 102 includes a handle 1310. This makes handling easier.
The container 102 optionally includes a maintenance opening 1312 including a cover (for example on its upper side or its cover 102d). This additionally makes handling easier.
The fluid guiding device 1450 can, for example, include a meandering fluid exchange channel (for example similar to a siphon). The fluid guiding device 1450 can include, for example, one or more than one constriction of the fluid exchange cross section.
According to various embodiments, the fluid guiding device 1450 can include an overflow protection device 1440 and/or a suction protection device 1442.
The overflow protection device 1442 is illustratively configured to inhibit the liquid from entering the extraction fitting 104 from the cavity 102h, thus increasing the reliability of the extraction. Specifically, the overflow protection device 1442 can be configured so to block liquid transport through the fluid guiding device 1450 into the extraction fitting 104 when the fluid guiding device 1450 is not subjected to a gas pressure differential (i.e., only gravitationally driven) and the liquid in the cavity 102h has a level below a threshold value (also referred to as overflow level). For example, the overflow level can be less than the trigger level and/or greater than approximately 0.5 cm, for example, than approximately 1 cm, for example, than approximately 2 cm, for example, than approximately 3 cm.
The overflow protection device 1440 shown here as an example can, for example, include a wall (also referred to as a retaining wall) that protrudes into the container 102 from below. A trough can thus be formed between multiple overflow protection devices 1440, into which the cavity 102h protrudes.
The suction promoting device 1442 is illustratively configured to encourage the liquid from the cavity 102h to enter the extraction 104 when the extraction occurs (for example, when the fluid guiding device 1450 is subjected to a gas pressure differential). Specifically, the suction promoting device 1442 can be configured so to block a gas exchange through the overflow protection device 1440 when it is subjected to a gas pressure differential and the liquid has a level above a threshold value (also referred to as extraction level). For example, the extraction level can be less than the trigger level and/or than the overflow level, for example, less than approximately 5 cm, for example, than approximately 3 cm, for example, than approximately 1 cm.
The suction promoting device 1442 shown here as an example can, for example, include a wall (also referred to as a suction wall) that protrudes into the container 102 from above (and is at a distance from the bottom). The distance between the bottom 102b of the container 102 and the suction wall can be, for example, less than approximately 5 cm, for example approximately 3 cm, for example approximately 1 cm.
The actuator 1302 can also include an input fitting 1104e which couples the waste liquid-collecting arrangement 151, for example its extraction fitting 104, to the extraction valve 1104. The actuator 1302 can include an output fitting (concealed in the view) that couples a pump system 1202 or manifold 1120 to the extraction valve 1104. The actuator 1302 can furthermore include a control fitting 1104s that couples the control device 1002 to the drive device 1004.
The waste liquid-collecting arrangement 151 can be coupled to multiple liquid sources 1110, of which each liquid source 1110 is coupled to at least one waste liquid feed of the multiple first waste liquid feeds 108 or the multiple second waste liquid feeds 118. For example, a first liquid source 1110 can be coupled to the first waste liquid feed 108a, a second liquid source 1110 to the second waste liquid feed 118a, and/or a third liquid source 1110 to the additional first waste liquid feed 108b.
Examples of a liquid source 1110 include: a refrigerator, a freezer, an air conditioner, a heat exchanger, a cool box, a chiller (for example a compression chiller), a refrigeration unit, etc. More generally, the liquid source 1110 can be configured to extract thermal energy and to emit it elsewhere.
The liquid source 1110 can include, for example, a liquid outlet (for example coupled to a trough and/or drainage channel) which is coupled to the waste liquid-collecting arrangement 151. The liquid outlet (for example a condensate outlet) can be opened in the direction of gravitation. For example, the liquid source 1110 can be configured for gravity drainage.
The waste liquid drainage system 153 can include a negative pressure line 1120 (also referred to more illustratively as a manifold 1120). The manifold 1120 can, for example, be arranged above the one or more than one 1110 and/or can have a negative pressure in the interior. Alternatively or additionally, a height position of the manifold line 1120 can be approximately 0.5 m or greater than approximately 0.5 m (meters), for example approximately 1 m or greater than approximately 1 m, for example approximately 2 m or greater than approximately 2 m, for example approximately 3 m or greater than approximately 3 m, for example approximately 4 m or greater than approximately 4 m, for example approximately 5 m or greater than approximately 5 m, for example approximately 6 m or greater than approximately 6 m, for example approximately 7 m or greater than approximately 7 m, for example approximately 8 m or greater than approximately 8 m, for example approximately 9 m or greater than approximately 9 m.
The waste liquid-collecting arrangement 151 can include a riser line 1102 (illustratively a vertical negative pressure line, also referred to as a lifting line), which is coupled to the extraction fitting 104. The riser line 1102 can, for example, include or be formed from a pipe (also referred to as a lifting pipe).
The riser line 1102 can be coupled to the manifold 1120, for example, by means of the extraction valve 1104 (if present). The extraction valve 1104 can be configured, when brought into a closed state, to interrupt the fluidic connection between the collecting space 102h and the manifold 1120. The extraction valve 1104 can be configured, when brought into a open state, to cancel the interruption of the fluidic connection between the collecting space 102h and the manifold 1120. Extraction can include bringing the extraction valve 1104 in an open state.
The waste liquid drainage system 153 can include the pump system 1202, which is configured to generate negative pressure (for example, vacuum) in each negative pressure line 1120. The pump system 1202 can include one or more than one pump. For example, the pump system 1202 can be connected to a sewer that runs underground.
The pump system 1202 can be configured to regulate the pressure (the negative pressure) in the manifold 1120, for example to a value in a range from approximately 0.4 bar to approximately 0.6 bar.
The waste liquid-collecting arrangement 151 (for example, a direct vacuum drainage unit) includes: the collecting container 102; multiple connecting lines 202 (for example, including hoses and/or pipes) which are connected to the devices 1110 to be emptied and the collecting container 102 (also referred to as collecting container); the extraction fitting 104 (for example, including an outlet hose or outlet pipe) connected to the collecting container 102 and the suction line 1102; the suction line 1102; the vacuum emptying valve 1104 (also referred to as the vacuum outlet valve); and the controller 1002 (also referred to as a control unit).
In operation, liquid from each of the devices 1110 to be emptied may be freely drained by gravity into the collecting container 102 via the connecting line 202 (for example, including connecting hoses 202 or connecting popes 202) connected to the inlet nozzles. The collecting container 102 can gradually be filled with liquid up to a trigger level, which is detected (for example monitored) by means of the level switch 902 or sensor 902. The liquid to be emptied can optionally fill the connecting lines 202. As a result, the absorption capacity for liquid can be expanded beyond that of the collecting container 102 itself. The overall length of all connecting lines 202 can be adapted to the respective operating conditions and does not have to be invariant. The free (blind) inlet nozzles an be closed accordingly.
The air in the collecting container 102 above the liquid level can be vented via the vent line 802 (for example, including a vent hose or vent tube) connected to the left or right pressure compensation fitting 704 (also referred to as the vent fitting). The choice of the vent fitting 704 (for example position either left or right) can depend on the particular installation conditions, whichever is more applicable. The unused (blind) vent fitting 704 (if present) can be closed accordingly. The vent line 802 (for example a vent hose) can be configured in such a way that its open end (also referred to as an inlet opening) is arranged above an upper edge of the inlets of the devices 1110 to be drained. The vent line 802 can optionally include a check valve, a nozzle, a connecting piece, or a combination thereof.
The collecting container 102 can be or become connected to the suction line 1102 by means of a extraction fitting 104, for example, an outlet line (for example, an outlet hose or an outlet pipe) connected thereto, which is connected to the left or right extraction fitting 104. The choice of the extraction fitting 104 (for example position either left or right) can depend on the particular installation conditions, whichever is better in accordance with the direction of the suction line 1102. The unused (blind) extraction fitting 104 (if present) can be closed accordingly. The length of the optional outlet line can vary depending on the specific installation situation.
When the liquid to be drained has reached the trigger level of the level switch 902 or sensor 902, this triggers the opening of the extraction valve 1104 (also referred to as the vacuum outlet valve) on the suction line 1102. As a result, the negative pressure provided in the manifold 1120 (for example, a pipe system) extracts the liquid from the collecting container 102 and the connecting lines 202 via the suction line 1102 and the pump system 1202 (also referred to as the vacuum system). Thereafter, the extraction valve 1104 is automatically closed and the waste liquid-collecting arrangement 151 is ready to collect the next portion of liquid from the devices 1110 to be emptied.
To achieve greater reliability, the liquid can optionally be inhibited from flooding the outlet line due to gravity. For this purpose, each extraction fitting 104 (for example the outlets of the collecting container 102) can open into an overflow protection device (not shown).
Optionally, each extraction fitting 104 (for example the outlets of the collecting container 102) can open into a suction promoting device in order to achieve a better suction effect.
The coupling of a liquid source to a waste liquid feed (for example its feed fitting) can include the latter being connected to one another fluidically and/or sealed to the outside. Waste liquid (for example condensate) discharged from the liquid source can thus be received by means of the waste liquid feed and fed to the collecting space 102h.
The method 1900 can, in 905, optionally include switching one or more than one inlet-side valve, for example of the multiple first waste liquid feeds 108 and/or the multiple second waste liquid feeds 118.
The switching can include, for example, bringing an inlet-side valve of one waste liquid feed of the multiple first waste liquid feeds 108 or the multiple second waste liquid feeds 118, which is coupled to a liquid source, into an open state.
The switching can include, for example, bringing an inlet-side valve of one waste liquid feed of the multiple first waste liquid feeds 108 or the multiple second waste liquid feeds 118, which is not coupled to a liquid source, into a closed state.
The method 1900 can optionally include, in 1907, coupling the extraction fitting 104 to a pump system.
The method 2000 can furthermore include, in 2005, extracting the waste liquid from the collecting space 102h through the extraction fitting 104 by means of a negative pressure applied to the extraction fitting 104. The extraction 2005 can optionally include bringing the extraction valve 1104 into an open state, for example for the open duration, and for example bringing it into the dosed state after the open duration has elapsed.
The method 2000 can optionally include, in 2007, detecting the waste liquid in the collecting space 102h (also referred to as liquid detecting). The liquid detection 2007 can include detecting an actual state (for example actual level) of the waste liquid in the collecting space 102h.
The extraction 2005 may optionally be performed based on a result of the liquid deduction. The extraction 2005 can take place, for example, in response to the result of the liquid detection meeting a criterion (also referred to as a trigger criterion). The result of the liquid detection can include an actual state of the waste liquid in the collecting space 102h, for example an actual level of the waste liquid in the collecting space 102h. The criterion can be met, for example, when the actual level of the waste liquid exceeds a threshold value (also referred to as the trigger level).
