How heat is transferred in refrigerator
WebA heat pump is energy saving technology that conveys heat without the need to generate heat. There is heat in the air even in places that are generally considered cold: for example, the North and South poles. However, because the amount of heat is small, these places feel cold. When the amount of heat is large, the temperature is high. WebIn fluid thermodynamics, a heat transfer fluid is a gas or liquid that takes part in heat transfer by serving as an intermediary in cooling on one side of a process, transporting and …
