Most homes use air-source heat pumps, which run outside air through a series of coils that extract heat energy. This valve is the component responsible for changing the direction refrigerant moves through the heat pump, and that determines if the heat pump is in heating or cooling mode. 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.
