Principle of Air Source Heat Pumps: Renewable Heating Solutions
When the air source heat pump is in operation, the evaporator absorbs heat from the ambient heat energy in the air to evaporate the heat transfer working fluid. The working fluid vapor is compressed by the compressor and the pressure and temperature rise, and the high temperature vapor passes through a special ring bonded to the outer surface of the water storage tank When it is piped, the condenser condenses into liquid and transfers the heat to the water in the air source heat pump storage tank.

The heat transfer working fluid of the air source heat pump is a special substance. Its boiling point is minus 40°C under normal pressure and its freezing point is below minus 100°C. The substance is liquid when it is cold, but it is easy to evaporate into gas, and vice versa. In actual operation, the evaporation limit temperature of the heat transfer medium in the air source heat pump is about minus 20°C, so the ambient temperature of 5°C is also "hot" to such a low temperature, even the temperature of snow, such as 0°C , It’s also hot in comparison, so some heat can still be exchanged
