The physics of refrigeration
WebbThe basic principle behind the working of a refrigerator is the second law of thermodynamics; more specifically, Clausius’s statement of the second law of thermodynamics, which states, “Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time.”.
