WebbRefrigerators and heat pumps are examples of heat engines which cause energy to be transferred from a cold area to a hot area. Usually this is done with the aid of a phase change, i.e., a refrigerant liquid is forced to evaporate and extract energy from the cold area. Then it is compressed and forced to condense in the hot area, dumping its ... WebbIn the process of refrigeration, unwanted heat is taken from one place and discharged into another. The common refrigerator which we have in our homes, works on the principle of … WebbThe science of refrigeration relies on the Second Law of Thermodynamics — everything tries to maintain the same temperature over time. Heat naturally moves from high-temperature areas to low-temperature ones.
