WebMay 22, 2024 · In general, a heat pump is a device that transfers heat energy from a heat source to a “ heat sink “, but in this case the transfer occurs in the opposite direction of spontaneous heat transfer by absorbing heat from a cold space and releasing it to a … WebThe first key to understanding how heat pumps actually work is to understand heat energy (which physicists call enthalpy ). This is the amount of energy stored in a particular amount of a particular substance as heat, relative to absolute zero. Heat energy is expressed as energy per mass (BTU/lb in the US; kilojoules/kilogram everywhere else).

WebA heat pump is a device that pulls the energy out of air for the purpose of either heating or cooling a space. This process is known as space conditioning. Heat pumps operate as a heat engine in reverse, as they do … WebHere’s how it works: 1. The refrigerant comes into the compressor as a low-pressure gas. It is then “compressed” to become a high-pressure gas. The gas then flows through the condenser coil . Here the gas “condenses” to a liquid, and gives off its heat to the outside air. The liquid then moves to the expansion valve under high pressure.
