WebApr 13, 2016 · Part 1: Basics & Traditional method (with sensor) COP stands for Coefficient Of Performance and indicates the efficiency of heating and cooling machines. The COP is defined by the ratio heat dissipation and electrical power intake. It’s like the efficiency of the machine, but higher than 100%. It could be less than 100% for a machine not ... WebMay 1, 2024 · The energy analysis of a gas refrigeration system is similar to that of the vapor refrigeration system except that the gaseous fluid is treated as an ideal gas. Therefore, the enthalpy and entropy equations are written as [ 5 ]: ∆h = (he − hi) = cp∆T = cp(Te − Ti) E21. ∆s = (se − si) = cp ln Te Ti − R ln Pe Pi E22.
