Question: 1 / 400

What is the purpose of a heat pump in HVAC systems?

To provide only cooling

To transfer heat from one location to another

The purpose of a heat pump in HVAC systems is to transfer heat from one location to another. This is a fundamental function that allows the system to provide both heating and cooling depending on the needs of the space. In heating mode, a heat pump extracts heat from the outside air, ground, or water and transfers it indoors, effectively warming the space. Conversely, in cooling mode, it removes heat from indoors and expels it outside, thereby cooling the living environment.

The efficiency of a heat pump comes from its ability to move heat rather than generate it through combustion or electric resistance, making it an energy-efficient option for climate control in buildings. This versatility in operation is what distinguishes heat pumps from systems designed solely for heating or cooling.
