Refrigerating Effect in Enthalpy Formulas

Refrigerating Effect is the cooling capacity of a refrigerant in a vapour compression refrigeration cycle, measured in terms of heat energy absorbed from the surroundings. And is denoted by R_E. Refrigerating Effect is usually measured using the Kilojoule per Kilogram for Heat of Combustion (per Mass). Note that the value of Refrigerating Effect is always negative.
