1. How Does an ASHP Work?

An air source heat pump (ASHP) is a highly efficient system that uses the principles of thermodynamics to provide both heating and cooling for your home. It operates by transferring heat from the outdoor air to the indoor space during the heating mode and reverses the process during the cooling mode. This innovative technology utilizes a combination of electrical power and the natural heat exchange properties of the air to regulate the temperature inside your home.

1.1. Overview of ASHP Operation

ASHPs work by extracting heat from the outside air using a refrigerant. The refrigerant, which is a special fluid designed to change states at low temperatures, absorbs heat from the outdoor air and becomes a gas. The gas is then compressed, which increases its temperature and pressure. This hot gas is then passed through a heat exchanger where the heat is transferred to the air or water inside your home. After releasing the heat, the refrigerant condenses back into a liquid and the cycle repeats.
