The basic working principle of the air source water heater is circulation. The low temperature low pressure refrigerant flows from the evaporator and is processed by the compressor.
This changes the refrigerant into a high temperature high pressure gas which enters into the condenser and exchanges heat into the water, the gas is condensed back into a liquid which transmits a large amount of heat into the water and its temperature is increased.
Continually, the high pressure low temperature liquid has its pressure reduced by the throttling device and absorbed heating from the environment air through the working evaporator and turned into low pressure gas and finally absorbed again by the compressor for circulated working of the whole system for heating water.
