WebThe transfer of heat goes from the hot object to the cold object. We could imagine a system in which the heat would instead be transferred from the cold object to the hot object, and such a system would not violate the first law of thermodynamics. The cold object would get colder and the hot object would get hotter but energy would be conserved.

WebCycle of heat transfer The cycle starts with refrigerant. It is a liquid entering the expansion device. When it passes through, the sudden drop in pressure makes it expand cool and turn into a gas. When refrigerant flows around the evaporator coil, it absorbs and removes heat from the food stored inside. This period directly makes food cold.
