Quizplus · Accepted Answer

Check valves are included in heat-pump-style room air conditioners to ensure the correct direction of refrigerant flow. They allow refrigerant to flow in one direction while preventing it from flowing in the opposite direction. This is important for the proper functioning of the heat pump, which relies on the correct movement of refrigerant between the indoor and outdoor units.
