[0050] In one embodiment, the present invention describes a water cooling system designed for the efficient cooling of overhead tank water used in routine household activities such as showering and kitchen utility. The system incorporates a tank where overhead tank water is supplied and circulated through an outer circuit surrounding the tank, known as the evaporator coil. Here, refrigerant gas absorbs heat from the water inside the tank, effectively lowering its temperature from ambient levels to a comfortable range of 10-15 degrees Celsius. This cooling capability is particularly beneficial in regions with consistently high temperatures exceeding 30 degrees Celsius, ensuring that users have access to cool water throughout the summer months.

This initiates the cooling process, allowing the system to efficiently cool the incoming water to the desired temperature range, providing a continuous supply of cool water for various domestic and commercial applications.

[0052]

[0052] In one embodiment, the present invention describes the method of operating a water cooling system, detailing the sequence of operations involved: Firstly, the thermostat 130 activates the system upon detecting high temperatures in the water entering the system's tank. Subsequently, the refrigerant within the evaporator coil absorbs heat from the water, effectively cooling it. The cooled water is then distributed to the tap as needed, thereby lowering its temperature for usage. Following this, the refrigerant, now in the form of a low-pressure gas, proceeds to the compressor where it is compressed into a high-pressure, high-temperature gas. This high-pressure gas then moves to the condenser coil where it releases the absorbed heat into the surrounding air, causing it to cool and condense into a liquid state. The high-pressure liquid refrigerant then passes through the expansion valve, which reduces its pressure, preparing it to repeat the cycle by evaporating once again in the evaporator coil. This cyclic process ensures continuous cooling of water within the system, maintaining a consistent supply of cooled water for various domestic and commercial applications.

[0053] EXAMPLES

[0053] Considering an example of the cooling system Wateregerator for a residential application in a Hot Climate the "Wateregerator," is installed in a residential setting in a region where ambient temperatures regularly exceed 35 degrees Celsius. In this application, the Wateregerator is installed indoor as per requirement e.g. washroom. Kitchen, pool etc. with the system 100 connected via an inlet pipe to supply water from the tank. The internal tank 114 of the Wateregerator, with a capacity of 5 / 10 / 15 / 20 / 25 liters or more as per requirement, receives the hot water and begins the cooling process when the thermostat 130 detects the high temperature. The thermostat 130 activates the system 100, causing the refrigerant (R134a) to circulate through the evaporator coil 126 that surrounds the internal tank 114. As the refrigerant absorbs heat from the water, the water temperature drops to a comfortable 10 degrees Celsius.

[0054]

[0054] Once the water is cooled, it is distributed through the tap to the household’s various fixtures, including showers and kitchen faucets. The low-pressure refrigerant gas then flows to the compressor 102, which compresses it into a high- pressure, high-temperature gas 104. This gas is directed to the condenser coil 128, where it releases the absorbed heat into the surrounding air, cooling and condensing back into a liquid state. The high-pressure liquid 110 refrigerant then passes through the expansion valve, reducing its pressure and preparing it to absorb heat again in the evaporator coil 126. The cycle of cooling, compression, heat release, and pressure reduction repeat continuously, providing a consistent supply of cooled water throughout the day.

[0055] Considering another example 2 for a commercial kitchen in an office building the Wateregerator is implemented in a commercial kitchen within an office building where water temperatures often rise above 30 degrees Celsius due to high usage and ambient conditions. The system is installed near the kitchen sink area, with an inlet pipe connected to the overhead water tank that supplies hot water to the Wateregerator. The internal tank of the system, with a capacity of 5 / 10 / 15 / 20 / 25 liters or more as per requirement, fills with hot water, and the thermostat 130 activates the cooling process when it detects an elevated temperature. The refrigerant, such as R134a, circulates through the evaporator coil surrounding the tank, absorbing heat from the water and reducing its temperature to around 10 degrees Celsius. The cooled water is then made available at the sink tap, enhancing the comfort and efficiency of kitchen operations. The low-pressure refrigerant gas is directed to the compressor, which increases its pressure and temperature. The high-pressure gas then moves to the condenser coil, where it releases the absorbed heat into the air and condenses into a liquid. The liquid refrigerant then passes through the expansion valve, which reduces its pressure, preparing it for another cycle of heat absorption in the evaporator coil.
