Heat pump - Wikipedia

A heat pump is a device that transfers heat energy from a source of heat to what is called a thermal reservoir.Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one.A heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink.
