What is the primary function of the compressor in a heat pump?

The primary function of the compressor in a heat pump is to condense refrigerant. In the operation of a heat pump, the compressor plays a crucial role by pressurizing the refrigerant, which raises its temperature as it passes through the compressor. This pressurized, high-temperature refrigerant then moves to the condenser, where it releases heat into the indoor space, thereby warming the home during heating cycles.

Understanding the role of the compressor helps to grasp the overall refrigeration cycle involved in heat pumps. The compressor ensures the efficient circulation of refrigerant throughout the system, enabling the heat pump to transfer heat from one place to another, whether it's extracting heat from the outdoor air or delivering heat to the indoor environment.
