Refrigeration System Quiz

It is the amount of heat absorbed by circulating refrigerant in the evaporator coil of the refrigeration system. By heat balance this amount of heat is the same as the amount of heat removal from the concern space or product to be cold, considering adiabatic heat transfer with proper insulation of the concern space.
