Heat Pump Basics

The science behind heat pumps

Heat pumps transfer heat from one location to another, using a refrigerant as the medium for heat exchange. In heating mode, a heat pump absorbs heat from the outside air, the ground, or a water source and transfers it indoors.

In cooling mode, the process is reversed, with the heat pump extracting heat from the indoor air and releasing it outside. This heat transfer process is made possible by the refrigeration cycle, which involves the continuous circulation of refrigerant through various components.

Components and operation

A typical heat pump system comprises an outdoor unit (compressor and condenser), an indoor unit (evaporator and air handler), refrigerant lines, and a thermostat or control system.

The key components work together continuously to move heat from one location to another, providing efficient heating and cooling for your space.

The refrigeration cycle: Heating and cooling modes

The refrigeration cycle is the heart of the heat pump’s operation. In heating mode, the refrigerant absorbs heat from the outdoor environment as it evaporates in the outdoor unit. The refrigerant then travels through the refrigerant lines to the indoor unit, where it releases heat as it condenses.

This process effectively warms indoor air. In cooling mode, the cycle is reversed, with the refrigerant absorbing heat from the indoor air and releasing it outdoors.
