Operation and Heating Cycle of a Heat Pump
The home heating cycle of a heat pump functions by taking heat in from the air outside, heating it further, and using this cozy air to warm interior air. It does so by adhering to process: Liquid refrigerant soaks up the warmth in the “evaporator” from the exterior air, becoming a gas. The cooling agent is put through a “compressor,” which raises the pressure of the gas, boosting its temperature.
