Refrigerant: History, Requirements and desirable properties & Numbered classification of refrigerants

Refrigerants are working fluids that carry heat from a cold environment to a warm environment while circulating between them. For example, the refrigerant in an air conditioner carries heat from a cool indoor environment to a hotter outdoor environment. Similarly, the refrigerant in a kitchen refrigerator carries heat from inside the refrigerator out to…
