What is Thermodynamic Analysis of Refrigeration about?

Here are the key steps to solve this problem: 1. Given: Refrigerant R-134a, Tevap = -10°C, Pcond = 0.9 MPa 2. Use refrigerant tables to find: - Hevap = 200 kJ/kg - Hcond = 400 kJ/kg 3. Calculate COPR,ideal: COPR,ideal = Qevap/Wcompressor = (Hcond - Hevap)/ (Hcond - Hevap) = 1/(1-Tcold/Thot) = 1/(1-263/273) = 2.33 4. Calculate COPR,Carnot:
