= = - sat 10.8 A vapor refrigeration cycle utilizes a compressor which has isentropic efficiency of no- 80%. The refrigerant is R134a, with mass flow rate m 0.12 kg/s. The compressor inlet condition is T 246.79 K, x= 100%, and the condenser exit condition is T sat = 312.54 K, X = 0%. Determine (a) the COP, (b) thermal cooling power (TR), and (c) mass flow of geothermal water through the condenser having a temperature rise of AT = + 20 °C (assuming the specific heat of liquid water is constant at op,w - 4.18 kJ/kgK . Use Appendix A.11 for thermodynamic properties of R134a and interpolate where necessary or use Linstrom and Mallard (2017–2021). =
