REFRIGERATION CYCLES Carnot Cycle We start discussing the well-known Carnot cycle in its refrigeration mode. Figure 1: Carnot Cycle In this cycle we define the coefficient of performance as follows: COP = qL TL = w TH − TL (1) Which comes from the fact that w = qH − qL (first law) and qL = TL Δs ‚ qH = TH Δs (second law). Note that w is also given by the area of the rectangle. Temperature differences make the COP vary. For example‚ the next figure shows how COP varies with
