Patent ID: 6973958

Claim:
A heat transfer apparatus comprising: a first heat exchanging system including a condenser and a heat exchanger coupled together, a compressor coupled between said condenser and said heat exchanger for pumping a heat exchanging fluid through said condenser and said heat exchanger, a filter, an expansion valve, and a solenoid valve coupled between said condenser and said heat exchanger, for filtering the heat exchanging fluid and for controlling a flowing of the heat exchanging fluid through said first heat exchanging system, a second heat exchanging system including a water inlet for receiving water, a water pump coupled to said water inlet to force the water from said water inlet into said heat exchanger, a water filter and an ion exchange filter coupled between said water pump and said heat exchanger, to filter negative ions, positive ions, mineral materials, and/or impurities from the water, and for decreasing an electric conductivity of the water, a switch coupled between said ion exchange filter and said heat exchanger, to control the water flowing into said heat exchanger, a water tank coupled to said heat exchanger, and coupled to an outlet, for supplying the water of lower water temperature and lower water pressure out of said second heat exchanging system, said water tank including an entrance and an exit, a water detector coupled to said water tank, to detect water quality in said water tank, an electric conductometer coupled to said water detector, to display an electric conductivity of the water in said water tank, a heater coupled to said water tank, to selectively heat the water in said water tank, a temperature detecting member coupled to said water tank, to detect a water temperature in said water tank, to control and to actuate said heater to heat the water in said water tank when said temperature detecting member has detected that the water temperature in said water tank is lower than a predetermined temperature, and to maintain the water temperature in said second heat exchanging system, a water cycling system including a water reservoir coupled to said entrance of said water tank, to receive the water from said water tank, said water reservoir including a discharge port coupled to said water pump via a control valve, to supply the from said water reservoir to said water pump of said second heat exchanging system, a pressure detecting member coupled to said water reservoir, to detect a pressure in said water reservoir, and to actuate said control valve to supply the water from said water reservoir to said water pump of said second heat exchanging system, and to maintain the water pressure in said second heat exchanging system, and an air relief valve coupled between said water pump and said water filter, to relieve air bubbles generated within the water, and to reduce shocks and vibrations that may be generated within said second heat exchanging system.
