The key components involved in the operation of an air source heat pump are the evaporator, compressor, condenser, and expansion valve. The heat pump uses a refrigerant that circulates through these components, absorbing heat from the outdoor air and releasing it indoors.

1. Evaporator: The evaporator is located outside and absorbs heat from the surrounding air. As the refrigerant flows through the evaporator, it evaporates, turning into a gas and absorbing heat energy in the process.

2. Compressor: The compressor is responsible for increasing the pressure and temperature of the refrigerant gas. By compressing the gas, the compressor raises its temperature, making it ready for the next stage of the process.

3. Condenser: The condenser is located inside your home and acts as a heat exchanger. The hot refrigerant gas passes through the condenser, releasing heat into the indoor air. As a result, the refrigerant condenses back into a liquid state.

4. Expansion Valve: The expansion valve regulates the flow of the refrigerant and reduces its pressure. As the pressure drops, the refrigerant cools down and expands, preparing it to absorb heat again in the evaporator.

This continuous cycle of heat absorption, compression, condensation, and expansion allows the air source heat pump to provide both heating and cooling for your home. By extracting heat from the outdoor air, even in colder temperatures, these heat pumps can efficiently warm your home without relying solely on electrical resistance heating.

Components of an Air Source Heat Pump

In addition to the core components mentioned above, air source heat pumps also consist of other important elements that contribute to their overall functionality.

1. Fan: The fan, located in the outdoor unit, helps draw outdoor air over the evaporator coil to facilitate heat transfer.

2. Reversing Valve: The reversing valve allows the heat pump to switch between heating and cooling modes. It controls the direction of the refrigerant flow, enabling the heat pump to either extract heat from the outdoor air or release heat outdoors.

3. Air Filters: Air filters prevent dust, dirt, and other particles from entering the heat pump system, keeping it clean and functioning efficiently. Regular filter maintenance is essential to ensure optimal performance.
