Experiment of a split air conditioner combined with ice storage and water heater

In the split air conditioner storage tank is direct connected with the air conditioner, and charging during off-peak electrical demand period, and in the daytime storage coils are used as super cooling exchanger to supercool the refrigerant from the condenser, improving the coefficient of performance (COP) of the air conditioner. This unit can also supply hot water by absorbing heat reject in the condenser. The prototype experiment in operation proves that the equipment is working well. Compared with the original air conditioner, the average cooling capacity increases by 28.2%, and COP increases by 21.5%.
