How heat pump air conditioner works
A heat pump is a mechanical-compression cycle refrigeration system that can be reversed to either heat or cool a controlled space.
Installation for this type of system typically consists of two parts:
An indoor unit called an air handler and an outdoor unit similar to a central air conditioner,
but referred to as a heat pump.
A compressor circulates refrigerant that absorbs and releases heat as it travels between the indoor and outdoor units.
