They can provide the whole family with different hot water, heating and cooling needs with large water volume, high water pressure and constant temperature 24 hours a day, while consuming the least energy to meet the above requirements. Air-source heat pumps work according to the "reverse Carnot" principle. The reverse Carnot cycle principle works through the operation of the compressor system to absorb heat from the air to produce hot water. The specific process is: the compressor compresses the refrigerant, and the refrigerant with increased temperature after compression passes through the condenser in the water tank to produce hot water.
