WebDec 11, 2024 · The most widely used refrigeration cycle is the vapor-compression refrigeration cycle, the refrigerant enters the compressor as saturated vapor and is cooled to the saturated liquid state in the condenser. It is then throttled too the evaporator pressure and vaporizes as it absorbs heat from the refrigerated space. WebSep 9, 2024 · By the first law of thermodynamics, the denominator of the expression is Q 2 − Q 1, and for a reversible Carnot cycle, the entropy in equals the entropy out, so that Q 2 /Q 1 = T 2 /T 1. Therefore the coefficient of performance for a Carnot refrigeration cycle can be calculated from \[ \frac{T_{1}}{T_{2}-T_{1}}.\]
