OBJECTIVE—of this exercise is to determine the various coefficients of performance, COP. Specifically, these are the ideal and actual cycle COPs using the attached thermodynamic diagram for Refrigerant-12 (R12).
INTRODUCTION—A refrigeration cycle is a cycle which transfers heat from a low temperature sink to a high temperature sink by the application of energy from a third source. A refrigeration cycle differs from what is commonly called a heat pump in that the desired output is the heat transfer from the cold sink rather than the heat transfer to the hot sink.
