How does a cooling curve work

WebHow does heating and cooling work? An airconditioner removes heat and humidity from the room with the help of refrigerant using a compressor or a heating pump. A compressor … WebCooling Curves Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.
