Abstract: | Refrigeration coefficient, ε, is usually calculatedby using the First Law of Thermodynamics. In this paper, anew derivation process is introduced through the combinationof the Second Law of Thermodynamics with the First Law of Thermodynamics. As a result, two new calculationequations for refrigeration coefficient are proposed. Oneequation is equivalent to the common method, but its form isa little complicated for real calculation. Another equation is the further simplification, and can be used to calculate therefrigeration coefficient instead of common method with apermit error. |
