ABSTRACT:
The invention is an energy saving method that subcools previously condensed refrigerant causing an increase in the net refrigeration effect. A water pump is used to circulate cold water stored in a tank through a counter flow heat exchanger which is connected to the liquid refrigerant line just prior to the expansion device and after the existing condenser. Excess sensible heat is thus transferred to the water storage unit. The effectiveness of water cooling is thus achieved and yet water conservation is achieved since water is dispersed only when excessive sensible temperature has been accumulated in the storage unit. The temperature of the water in the storage tank is maintained by an aquastat mounted on the top which activates a solenoid dispersing heated water and admitting cool water as required. The subcooling of liquid refrigerant results in an increase in the heat collecting capacity of a refrigeration system (effective tonnage) and the reduction of excessive compressor head pressure thus reducing the electric power requirements by reducing running time and reducing the electric power needed to operate the compressor. In addition, reduced compressor head pressure reduces maintenance and repair costs by extending the compressor mean time between failure.
