About air-water heat pump

An air source heat pump system is another way of utilization of solar energy. A large portion of solar energy existed in the air, the heat is absorbed from the air by an outdoor unit called evaporator, refrigerant in the evaporator is in gaseous state, then the compressor increase the temperature and pressure of the refrigerant, after that, the refrigerant transfers its heat to the heating medium in condenser, the heating medium will bring the heat to your house heating system or for hot water. The refrigerant was reverted into liquid now, it will move to the evaporator again and start to collect the new energy for the air. The circling will keep running all the time.About air-water heat pump.
