An air source heat pump is a type of heating and cooling system that works by extracting heat from the outdoor air and transferring it inside. The process for Heating the Inside of the home works in the following steps:
- The outdoor unit of the heat pump contains a fan that pulls in air from the outside.
- The air passes over an evaporator coil containing a refrigerant. The refrigerant absorbs the heat from the air and turns it into a gas.
- The refrigerant gas is compressed by a compressor, which raises its temperature.
- The compressed and heated refrigerant is then sent to the indoor unit of the heat pump through a refrigerant line.
- In the indoor unit, the refrigerant releases the heat it absorbed outside and heats the indoor air.
- The heated indoor air is then distributed throughout the home or building through ducts or a ductless system.
[During the summer months, the heat pump can be reversed to cool the indoor air by extracting heat from inside and releasing it outside. The process works in the opposite direction, with the refrigerant absorbing heat from the indoor air and releasing it outside.]
Air source heat pumps are an energy-efficient and environmentally friendly option for heating and cooling, as they use less energy than traditional heating and cooling systems. They are particularly effective in moderate climates, where the outdoor temperature remains relatively consistent. If you are interested in installing an air source heat pump in your home or building, be sure to consult with a licensed HVAC contractor to determine if it is the right option for your needs.
