Compact Heat Pump

Working principle

1.Refrigerant is compressed into vapor with high temperature & high pressure when it goes through the compressor 

2.On the discharge side of the compressor, the now hot and highly pressurized vapor is cooled down through the heat exchange with the water in the tank until it condenses into a high pressuure, moderate temperature liquid

3.Then the pressure of the liquid refrigerant drops as it passes expansion valve

4.Finally, refrigerant absorbs heat from the surrounding air and evaporates into vapor with low temperature and low pressure and then it goes into compressor again

5.The cooled surrounding air could be blew to the rooms which needs fresh cooled air.
