SYSTEMS, METHODS AND APPARATUSES FOR AUTOMATIC REGULATION OF WATER TEMPERATURE
An apparatus is provided for automatic regulation of water temperature. The apparatus comprises a compressor for compressing a refrigerant, a condenser that receives refrigerant from the compressor and reduces the temperature of the refrigerant by exchanging the refrigerant's heat with air surrounding the condenser, an expanding valve that receives refrigerant from the condenser and transforms the refrigerant in a high pressure state to a low pressure state, and an evaporator that receives refrigerant from the expanding valve and facilitates heat exchange between the low temperature refrigerant and a high temperature water. The evaporator comprises of two adjacent chambers that share a common wall. The first chamber is configured to receive the refrigerant and the second chamber is configured to receive the water, and the refrigerant and water exchange heat through the common wall. The heat exchange results in the reduction of water temperature and an increase in the refrigerant's temperature.
The general inventive concepts relate to water conditioning and, more particularly, to systems, methods, and apparatuses for automatic regulation of water temperature.
BACKGROUNDIn many developing and developed countries around the world, water supply to a dwelling is typically stored in an outdoor elevated storage tank, from which location water flows to the dwelling's taps, faucets and outlets for consumption, typically via the operation of gravity. At such outdoor locations, the storage tank is susceptible to weather conditions such as extreme heat or extreme cold. For instance, in arid and semi-arid climatic conditions, water in such storage tanks may be heated up to 140° F. in the summer and may be cooled to near freezing temperatures in the winter.
Currently, users of such storage tanks are left with limited options to obtain temperature-regulated water. One such option is for users to consume water during parts of the day where temperatures are moderate, early mornings and late evenings for instance. Another option is for users to heat or cool the water using traditional heating and cooling appliances such as stoves and refrigerators respectively. As can be understood, such options are highly impractical for regular every-day use of water.
In view of the above, there is an unmet need for systems, methods and apparatuses for automatic regulation of water temperature which runs in conjunction with a dwelling's native water storage system and which allows the user to regulate water temperature in multiple ways.

Now, with particular reference to the drawings, exemplary embodiments of the invention are described below.
Apparatus 100 has a programmable electronic control module 700 (as shown in
In one embodiment, apparatus 100 has a cooling capacity of 6 kilowatts, a water flow rate of 1000 liters per hour (LPH), and supports power supply inputs of 110 Volts, 220 Volts and 347 Volts. Water flow rates in apparatus 100 are adjustable. Moreover, apparatus 100 is also equipped with an outlet water pressure compensation function, which is designed to set the water flow pressure at different levels depending on the needs of the user, typically between 30 psi and 80 psi. For example, flow rates or water pressures required for high-capacity dwellings, such as apartments, offices, hotels, factories, hospitals, shopping malls, and restaurants are different from the flow rates or water pressures required at residential dwellings. One of ordinary skill in the art will appreciate that any other type of technical parameters may be utilized in the present invention, without deviating from the spirit and scope of the present invention. For example, an alternate power supply input of 277 Volts or any other voltage input may be used in the invention. Other technical parameters for an exemplary embodiment of apparatus 100 are described in further detail in

Apparatus 100 is further described with reference to
Apparatus 100 and the components of apparatus 100 are preferably installed on a frame, with an enclosure wrapping the frame. In one embodiment, apparatus 100 and the components of apparatus 100 utilize corrosion resistant stainless steel construction. For instance, filters used in the construction of apparatus 100, the frame of apparatus 100 and enclosure wrapping the frame of apparatus 100 may all be made from a variety of corrosion resistant stainless steel material. Employing corrosion resistant stainless steel material is especially helpful in tropical, sub-tropical, arid and semi-arid climatic conditions where apparatus 100 may be exposed to severe weather conditions, and which, in the absence of employing corrosion resistant stainless steel material, may lead to degeneration of apparatus 100 through corrosion and/or rust. In other exemplary embodiment, natural or man-made materials such as metals, metal derivatives, hydrocarbons, hydrocarbon derivatives, plastics, and fiberglass may be employed in lieu of or in combination with the corrosion resistant stainless steel material. In one embodiment, other improvements to apparatus 100, such as utilizing dust proof enclosures, may also be employed to protect apparatus 100 from severe weather conditions.

With further reference to ECM 700, various input and/or display mechanisms are discussed. In one exemplary embodiment, power on/off mechanism 1 is configured to display a green or red indicator light, depending on whether ECM 700 is on or off respectively. When ECM 700 is on, activating the power on/off mechanism 1 would turn ECM 700 off, and would also turn the indicator light from a green color to a red color. When ECM 700 is off, activating the power on/off mechanism 1 would turn ECM 700 on, and would also turn the indicator light from a red color to a green color. In one exemplary embodiment, activating the reset key mechanism 19 for five (5) seconds locks the ECM 700 unit, in order to disable users from accidently activating any input and/or display mechanism. After ECM 700 is locked, activating the reset key mechanism 19 for an additional five (5) seconds will un-lock ECM 700 in order to enable users to activate any input and/or display mechanism of their choice. One of ordinary skill in the art will appreciate that the five second activation is not a limitation of the system, and any amount of time may be pre-set to achieve the locking and unlocking features described above. Additionally, ECM 700 may be configured such that the power on/off mechanism 1 is available to the user regardless of the locked/un-locked status described above.
With further reference to ECM 700 and the power on/off mechanism 1, in one embodiment, when power to the apparatus 100 is switched off, ECM 700 stops the compressor (reference A in
In one embodiment, ECM 700 starts the compressor (reference A in
Users may utilize the mode key mechanism 18 to choose the operating mode of the system. For instance, users may activate the mode key mechanism 18 to activate a single mode, or switch between two or more modes, including a cooling mode and/or a heating mode. In one embodiment, users may be able to change the ECM 700 mode even when ECM 700 is turned off. In one embodiment, users may utilize the options mechanism 20 and temperature adjusting key mechanism 21 in conjunction with each other. For instance, users may select the options mechanism 20 to review existing values of various system parameters such as output water temperature, coil temperature etc. In one embodiment, apparatus 100 may comprise a thermo element 106 (not shown), to continually measure an outdoor coil temperature. The thermo element 106 for sensing the outdoor coil temperature can take a wide variety of different forms. Examples include, but are not limited to, thermo couples, digital thermometers, or other temperature sensing devices that are positioned on the outdoor coil and are connected to the ECM 700 and provide a signal for the ECM 700 that can be processed by the ECM 700 to determine the outdoor coil temperature. Once the user arrives at a parameter of choice (e.g. output water temperature), the user may then utilize the temperature adjusting key mechanism 21 to increase or decrease the temperature setting of said parameter.
In one embodiment, users may utilize the time adjusting key mechanism 22 and reset key mechanism 19 in conjunction with each other. For instance, users may select the desired time, in hours, minutes, and/or seconds, by utilizing the time adjusting key mechanism 22, and then activate the reset key mechanism 19 in order to confirm the selected time. Additionally, ECM 700 may be configured such that the time adjusting key mechanism 22 is available to the user regardless of whether ECM 700 is turned on or off. The time mechanism 15 displays a default time, or the most recent time selected via the time adjusting key mechanism 22.
In one embodiment, users may utilize the timer setting mechanism 7 and reset key mechanism 19 in conjunction with each other. The timer setting mechanism 7 may be utilized to enable the user to pre-set a time at which ECM 100 turns on or off For instance, the user may pre-set the timer setting mechanism 7 to turn ECM 100 on every morning at a certain time, and to turn ECM 100 off every evening at a certain time. The timer setting mechanism 7 may be set to any time during the day, and is designed to aid the user to conserve energy, as well as to allow the user to customize the operation of apparatus 100 based on their unique needs. In one embodiment, if the timer setting mechanism 7 is configured to turn ECM 700 off at a time when ECM 700 is already off, ECM 700 will first be powered on, and then be powered off at said time. Similarly, if the timer setting mechanism 7 is configured to turn ECM 700 on at a time when ECM 700 is already on, ECM 700 will first be powered off, and then be powered on at said time. In another embodiment, if the timer setting mechanism 7 is configured to turn ECM 700 off at a time when ECM 700 is already off, no further action will take place. Similarly, in an embodiment, if the timer setting mechanism 7 is configured to turn ECM 700 on at a time when ECM 700 is already on, no further action will take place. In order to set a time utilizing the timer setting mechanism 7, users may select the desired time, in hours, minutes, and/or seconds, by utilizing the timer setting mechanism 7, and then activate the reset key mechanism 19 in order to confirm the selected time.
ECM 700 may also be configured to check for and detect certain faults or errors in the ECM 700 and/or the apparatus 100. Such checks and detections may be configured to take place automatically, without any user input. When ECM 700 checks for and detects a certain fault condition, a corresponding pre-set solution may be executed. In one embodiment, fault condition(s) may be represented as error code(s) in the error code mechanism 4. An exemplary list of error codes, reasons for the fault condition and the pre-set solutions are described below in Table 1.
In one embodiment, when any of the above listed fault conditions in Table 1 have been encountered and fixed, users may activate the reset key mechanism 19 to recover the normal operation of ECM 700.
With further reference to Table 1, an error code for winter anti-freeze protection (PO: 07) is described in more detail. Winter anti-freeze protection is configured to protect the components of apparatus 100 from freezing in low ambient temperatures. In one embodiment, apparatus 100 may comprise a thermo element 102 (not shown), to continually measure the ambient air temperature. The thermo element 102 for sensing the ambient air temperature can take a wide variety of different forms. Examples include, but are not limited to, thermo couples, digital thermometers, or other temperature sensing devices that are positioned in the ambient air and are connected to the ECM 700 and provide a signal for the ECM 700 that can be processed by the ECM 700 to determine the ambient temperature. When ambient air temperature reaches a preset temperature, 42° F. for example, the thermo element 102 sends signal to ECM 700. Consequently, ECM 700 closes all components of apparatus 100 and turns apparatus 100 off. ECM 700 may be configured such that when ambient temperature increases to a preset temperature, 48° F. for example, ECM 700 turns on again automatically to resume normal operations. In one embodiment, ECM 700 may be configured to check the return temperature of the water to initiate winter anti-freeze protection and the subsequent solution thereof.
ECM 700 may be configured to initiate anti-freeze protection for the heat exchanger (character 10 in
One of ordinary skill in the art will appreciate that additional protections may be configured in ECM 700, in addition to those described above. For example, a compressor running protection may be configured. In one embodiment, ECM 700 may be configured to initiate protection for the compressor (character 2 in
The above description of specific embodiments has been given by way of example. From the disclosure given, those skilled in the art will not only understand the general inventive concepts and attendant advantages, but will also find apparent various changes and modifications to the structures and methods disclosed. For example, the general inventive concepts are not typically limited to an apparatus configured to cooling water only. Thus, for example, use of alternative options, such as a cold winter option where a heating element and a heating tank are provided, are within the spirit and scope of the general inventive concepts. As a further example, the general inventive concepts are not typically limited to using apparatus 100 as part of a dwelling's water supply system. Apparatus 100 may also be configured as a stand-alone system. The difference between apparatus 100 as described above and a stand-alone system would be of capacity, especially in the size and availability of components. In a standalone system, a water supply unit is attached to the apparatus 100. Non-standard units, such as stand-alone units, are sized based on flow requirements as well as output water temperature requirements. The specifications of the components, such as the compressor, the condenser, and the evaporator (plate heat exchanger) are based on the requirements of water flow and desired output temperature. The higher the flow rate desired, the bigger the components and vice versa. If the apparatus 100 reaches the limits of an assembly, apparatus 100 may be cascaded into multiple units, which may or may not be contained in one assembly. As another example, although the embodiments disclosed herein have been primarily directed to using apparatus 100 as a general water supply device, the general inventive concepts could be readily extended to configure apparatus 100 to be used with other any apparatus which may perform other functions such as water purification. It is sought, therefore, to cover all such changes and modifications as fall within the spirit and scope of the general inventive concepts, as described and claimed herein, and equivalents thereof.
