Air Source Heat Pump How Does it Work

As the world moves towards more environmentally friendly heating solutions, air source heat pumps have become a new type of heating technology for homes.

The working principle of an air source heat pump is based on thermodynamics. Thermodynamics is the science of how heat, temperature, and energy are transferred from one place to another.

They consist of an evaporator, compressor, condenser, and expansion valve, operating in a continuous cycle.

1. A fan draws in air from the outside, and the air flows over the refrigerant.

2. The refrigerant absorbs heat from the air, turning into warm vapor.

3. The vapor passes through the compressor, producing high-temperature refrigerant and usable heat.

4. The heat in the hot refrigerant is transferred to the heating and hot water tanks through a heat exchanger.

5. After the heat is transferred to the house, the refrigerant cools down through the expansion valve, allowing the air source heat pump to absorb heat from the air and continue the cycle.
