Heat Pumps for Heating and Cooling The indoor and outdoor units are inter-connected with tubing and a heat transfer medium, known as a refrigerant, which is circulated through the loop to facilitate the desired heat transfer. With a special 4-way reversing valve, the refrigerating cycle can be switched to the heating or cooling mode. During heating, the outdoor unit serves as an evaporator to extract heat from air; the indoor unit performs condensation, and blows hot air into the room. The reverse happens during summer cooling, i.e. the heat pump takes heat out of the indoor air and rejects it outside. 2.2. Heating Mode Operation In the heating mode, the indoor coil functions as the condenser and the outdoor coil functions as the evaporator. Refer to the schematic of Air to Air Heat Pump in the heating mode below: 17
