Fundamentals of Refrigeration: Inside the World of Thermodynamics

24 min read

Refrigeration is based upon the principle of heat transfer, whereby a fluid known as a refrigerant is passed through an evaporator where heat is absorbed, thereby changing its state from a liquid to a gas. This heat is then expelled at the condenser, where the state of the refrigerant is changed back to liquid, and the cycle then repeats itself.
