The present disclosure relates to the field of methods and apparatuses controlling water temperature. In particular, the present disclosure relates to apparatuses and methods for controlling the water temperature of a pool.
There are many issues with the pool heaters that are available on today's market. In general, they are very costly to buy and to maintain. On average a pool heater will cost approximately 2500$ to 5000 $ or more to purchase and approximately 800$ for installation costs. Also, they can cost about 600$ to about 1200$ in energy costs (gas, propane, electricity) per year to operate in addition to maintenance costs. This energy consumption contributes to the green house gases that damage the atmosphere.
Another factor is the constant noise that most heaters produce. Indeed, most heaters generate a perpetual unpleasant buzz that can be annoying when enjoying the pool. They are also quite annoying for the neighbors as well.
Also, if the heater is defective, a technician is usually required in order to repair the problem, which can be costly. Other costs are generated when changing heating systems in order to go from fresh water to salt water. Also, traditional pool heaters need to be covered or stored during winter months in order to avoid damage to mechanical parts. However, even when well maintained, the average pool heater only lasts about 7 to 10 years.
Some cost effective pool heaters have been introduced on the market, but their main downfall remains that they are not efficient enough for client's needs. Indeed, since they rely on the sun to generate heat and have a relatively low energy conversion rate, they often fail to provide sufficient power in order to heat a normal sized pool. Other types of pool heaters have also been introduced on the market. Indeed, pool heaters relying on electricity or fossil fuels although effective are sadly not cost efficient.

Referring now to
The compost can comprise various organic materials. For example, it can comprise common organic waste materials such as table wastes, lawn clipping, dried leaves, etc. It can also comprises various other ingredients such as sawdust, chicken manure and poultry wastes, brewery wastes, seaweed and kelp, tobacco stems and waste, wool clippings, sewerage sludge, straw, hay, cattails, weeds and discarded plants from the garden, cotton nolls and wastes, paper scraps etc.
The housing 8 further defines a chamber opening 24 through which the compost may enter to be received within the composting chamber 16. The housing 8 further includes a lid member 32 for selectively covering the chamber opening 24 of the composting chamber 16. For example, the lid member 32 may be useful for avoiding spillage of the enclosed compost, preventing water from contacting the compost or avoiding animals or insects from having access to the inside of the compositing chamber 16.
Referring now to
Heat generated from fermentation of the compost received within the composting chamber 16 is at least partially transmitted to the conduit 40 and further to the water flowing through the conduit 40, thereby increasing the temperature of the flowing water. For example, the conduit 40 may be formed of a material having high heat conductivity for at least partially transmitting heat absorbed from the compost to the water flowing through the conduit, such as plastic, rubber, fiberglass, aluminum, or copper.
Continuing with
For example, the conduit 40 may be formed of a light absorbent material for absorbing heat from light incident thereon and for at least partially transmitting the absorbed heat to the water flowing through the conduit 40.
For example, the at least one translucent portion may further provide a greenhouse effect within the composting chamber 16. Light flowing through the translucent portion may be partially absorbed by the compost received in the composting chamber 16, the conduit 40 or both. Radiation or other types of waves being emitted from the compost or the conduit 40 are then trapped by the at least one translucent portion, thereby further contributing to increasing the amount of heat generated within the composting chamber 16.
For example, the at least one translucent portion may be a translucent window on an upstanding wall of the housing 8. For example, the at least one translucent portion may be formed of an insulating material for insulating the composting chamber 16 from an outer environment surrounding the housing 8.
According to one exemplary embodiment, almost the whole of the housing 8 may be formed of a translucent material so as to maximize the amount of light flowing into the composting chamber 16 and the heat generated therein. For example, upstanding walls 20 of the housing 8 are completely (or almost completely) translucent, while it is not required for the base of the housing 8 to be translucent because little light flows through the base of the housing 8. For example, and as illustrated, the upstanding walls 20 may be formed of a plurality of upstanding panels, which may each be a planar panel.
According to various exemplary embodiments, the upstanding walls 20 housing 8 may further include at least one heat absorbent portion for absorbing heat from light incident on the housing 8. The heat absorbent portion is further adapted to at least partially transmit the heat absorbed from the incident light through the housing 8 to at least partially heat the composting chamber 16.
According to various exemplary embodiments, the lid member 32 may be translucent for permitting light waves incident on the lid member 32 to flow through the lid member 32 into the composting chamber 16. The flow of light through the translucent lid member 32 may have the effect of heating the composting chamber 16. Additionally or alternatively, the light flowing through the translucent lid member 32 may be incident on the conduit 40, which further heats up the conduit 40 and the water flowing through the conduit 40. The at least one translucent lid member 32 may permit at least the flow therethrough of short length waves, such as ultra-violet waves.
For example, the translucent lid member 32 may further provide a greenhouse effect within the composting chamber 16. Light flowing through the translucent lid member 32 may be partially absorbed by the compost received in the composting chamber 16, the conduit 40 or both. Radiation or other types of waves being emitted from the compost or the conduit 40 are then trapped by the translucent lid member 32, thereby further contributing to increasing the amount of heat generated within the composting chamber.
According to one various exemplary embodiments, the lid member 32 may be dome-shaped and translucent for further increasing the greenhouse effect provided by the translucent lid member 32.
Referring back to
A base 48 of the housing 8 includes one or more drain slots 56. The drain slots 56 are sized to restrict passage therethrough of the compost received in the composting chamber 16 while also allowing flow therethrough of juices generated from fermentation of the compost. The temperature control apparatus 1 may further include a receptacle 64 disposed below the housing 8 for collecting juices flowing through the drain slots 56. The receptacle 64 may include an outlet 72 (e.g. second opening) for exiting juices collected within the receptacle 64.
Continuing with
For example, and as illustrated in
For example, and as illustrated in
At least one of the plurality of the elongated subconduits 104 extends in a radial direction in relation to the axis 88 of the housing 8 to define a radial width of the elongated subconduit 104. Furthermore, the elongated subconduit 104 extends in an angular direction in relation to the axis 88 to define an angular thickness.
Referring now to
According to various exemplary embodiments, the radial width 176 of the elongated subconduit 104 in the radial direction 180 is greater than its angular thickness. Where a plurality of the elongated subconduits 104 each have a radial width 176 greater than an angular thickness 182, the plurality of elongated subconduits 104 resemble a plurality of fin-like members arranged circumferentially about the axis 88. It will be appreciated that the fin-like elongated subconduits 104 increases the surface area of elongated subconduits 104 that are exposed to the compost received within the composting chamber 16, thereby increasing the amount of heat transmitted from the compost to the water flowing through the elongated subconduits 104 and further increasing the rate at which the temperature of the water can be increased.
According to some exemplary embodiments, the aeration duct 200 further includes at least one spacer member 224. The at least one spacer member 224 extends radially outwardly from the column 208. The at least one spacer member 224 includes at least one of the air pores of the aeration duct 200. For example, a bottom surface 232 of the spacer member 224 includes an opening defining one of the air pores. The opening is further in communication with the hollow channel defined by the hollow column 208. Providing the air pore on the bottom surface 232 of the spacer member 224 restricts entry of compost material into the air pore while still allowing flow of air into the composting chamber 16.

For example, the conduit 40 may be supported against an inner surface of the housing 8. For example, the conduit 40 is coiled circumferentially about the composting chamber 16 by being adhered to an inner surface of housing 8.
For example, a conduit support can be provided. The conduit support can be disposed inside the housing 8. The conduit support can be of various shapes. In an embodiment, the conduit support can have a general cylindrical shape. The conduit support can be open on one or both sides, therefore allowing compost to enter into the conduit support. The conduit support can be made of a material having high heat conduction, which therefore absorbs and transfers thermal energy rapidly. For example, the conduit support can comprise brass or copper or any metal known as a thermal conductor. The conduit member can be made of a perforated material for allowing oxygenation of the compost. The conduit support adapted to support the conduit 40 which is in the form of a coiled pipe. For example, the conduit 40 is supported and coiled circumferentially about the composting chamber 16 by being wrapped around an outer surface of the conduit support.
For example, the coiled conduit 40 is wrapped at least once around a conduit support inside the composting chamber 16. Wrapping the conduit 40 more than once around the conduit support increases the surface of the conduit 40 that is in contact with the surrounding compost and the conduit support. Since both the compost and the conduit support are hot when being in use, the conduit support being heated by a heat transfer from the compost during fermentation, they will both play a role in controlling and/or heating the temperature of the water circulating through the conduit 40.

A mixing portion 308 of the mechanism 300 is located within the composting chamber 16. The mixing portion 308 corresponds to a portion of the mixing mechanism 300 that is operable for mixing the compost received within the composting chamber 16. For example, the mechanism 300 may include a spine portion 316 extending axially through the housing 8. The mixing portion 308 may have mixing members 324 extending transversely from the spine portion 316, whereby rotation of the spine portion 316 causes rotational movement of the mixing members 324 to mix the compost received in the composting chamber 16. Alternatively, the mixing portion 308 may be a type of corkscrew that mixes the compost when rotated.
The mixing mechanism 300 further includes a handling portion 332 being located outside the composting chamber 16. The handling portion 332 is connected with the mixing portion 308 so that manipulation of the handling portion 332 outside the composting chamber 16 can cause mixing of the compost inside the composting chamber 16 by the mixing portion 308. For example, rotation of the handling portion 332 causes rotation of the spine portion 316 and the mixing member 324 to mix the compost. For example, the handling portion 332 can be manipulated to cause mixing of the compost received in the composting chamber 16 by the mixing portion 308 while the lid member 32 is covering the composting chamber 16.
Referring back to
The temperature control apparatus 1 according to the examples of
Continuing with
According to various exemplary embodiments, the inlet 44 of the conduit 40 includes a fluid splitter 392 for splitting the received water among a plurality of independent tubular subconduits. As illustrated in
Referring now to
For example, and as illustrated, the conduit 40 at least partially contacts an outer surface of the interior walls 400 to receive heat from the interior walls 400. For example, the conduit is coiled to surround the outer surface of the interior walls 200. By positioning the conduit 40 outside of the inner chamber 408, the conduit 40 is separated from the compost received within the inner chamber 408 by the interior walls 200. This prevents accumulation of compost within crevices formed by the conduit 40, thereby facilitating cleaning of the apparatus 1.
According to such exemplary embodiments, the lid member 32 may be operable to selectively cover an opening of the inner chamber 408.
According to such exemplary embodiments, the mixing portion 308 of the mixing mechanism 300 is positioned within the inner chamber 408 while the handling portion 332 is located outside the inner chamber 408. For example, the handling portion 332 can be manipulated while the lid member 32 is covering the inner chamber to cause rotation of the mixing portion 308 to mix the compost within the inner chamber 408.
For example, the outer surface of the interior walls is spaced apart from the inner surface of the housing to define an interior space 416. The interior space 416 may provide a partial insulating effect. For example, the interior space 416 at least partially insulates the conduit 40 from the housing 8. Where the housing 8 includes at least one translucent portion 356, the light waves flowing through the translucent portion 356 heats the interior space 416 and the conduit 40.
Referring now to
According to various exemplary embodiments, the temperature control system 480 may further include an automatic valve control system for automatically controlling the shut-off valves 488, 492 and the by-pass valve 496. For example, automatically controlling the valves 488, 492, 496 permits automatically controlling the water temperature. For example, automatically controlling the valves permits automatically maintained a desired or predetermined water temperature. For example, the desired temperature of the pool water can be of about 24° C. to about 35° C., about 24° C. to about 32° C., about 26° C. to about 32° C., about 26° C. to about 29° C., about 26° C. to about 27° C., about 28° C., or about 29° C.
The valve control system includes a controller, a temperature sensor, and electronically controlled shut-off and by-pass valves. The controller described herein may be implemented in hardware or software, or a combination of both. It may be implemented on a programmable processing device, such as a microprocessor or microcontroller, Central Processing Unit (CPU), Digital Signal Processor (DSP), Field Programmable Gate Array (FPGA), general purpose processor, and the like. In some embodiments, the programmable processing device can be coupled to program memory, which stores instructions used to program the programmable processing device to execute the controller. The program memory can include non-transitory storage media, both volatile and non-volatile, including but not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), flash memory, magnetic media, and optical media.
The temperature sensor can sense or monitor the water temperature. For example, water temperature may be measured at any one of the inlet 44 of the conduit 40, within the conduit 40, at the outlet 42 of the conduit 40, or at any location within the pool of water for which temperature is to be controlled. For example sensing includes taking a measurement of the water temperature. Monitoring, or variants thereof, as used herein refers to repeatedly sensing the water temperature over time. For example, monitoring can be carried out in a substantially continuous manner. It will be understood that substantially continuous monitoring is the result of repeated sensing at short time intervals apart (periodically or non-periodically) such that a plurality of discrete measurements closely spaced in time are made. As a result, the monitoring may appear to be continuous to a human operator. Moreover, substantially continuous monitoring may appear to be in real-time.
The water temperature measured by the temperature sensor is received by the controller. The controller then controls the shut-off valves and the by-pass valves based on the measured water temperature. For example, the controller determines whether a predetermined threshold water temperature has been reached. When the water temperature has exceeded the predetermined temperature threshold, the controller sends one or more control signals to actuate the shut-off valves to their closed positions and the by-pass valve to its open position, thereby directing flow through the by-pass valve and restricting flow into the conduit 40. When the water temperature is below the predetermined temperature threshold, the controller sends one or more control signals to actuate the shut-off valves to their open positions and the by-pass valve to its closed position, thereby directing flow into the conduit 40.
The shut-off valves and the by-pass valves may be any type of valve that may be electronically controlled. For example, the shut-off valve and the by-pass valve may each be a solenoid valve.
The apparatuses and methods described in the present disclosure comprise several advantages compared to traditional pool heaters. Heat being provided by only composting, very low costs are necessary to operate the apparatuses and methods. The apparatuses and methods necessitate very simple components. Compost comes from organic materials derived from plant and/or animal matter, which are produced as wastes by every household on a regular basis. No other energy sources in addition to the existing elements of the pool are required to heat the pool water. Repairing should not be required and if so, it should be mainly maintenance or very simple repairing steps. Finally, no noise is associated with use of such methods and apparatuses.
The present disclosure has been described with regard to specific examples. The description was intended to help the understanding of the disclosure, rather than to limit its scope. It will be apparent to one skilled in the art that various modifications can be made to the disclosure without departing from the scope of the disclosure as described herein, and such modifications are intended to be covered by the present document.
The present application is a 35 USC 371 national stage entry of PCT/CA2015/051085 filed on Oct. 26, 2015 and which claims priority on U.S. 62/068,092 filed on Oct. 24, 2014. These documents are hereby incorporated by reference in their entirety.
