LSHX with an effectiveness of 0.65 is used in a R-134a based refrigeration system. The evaporating and condensing temperatures are 3.2°C and 55.4°C respectively. Assuming the compression process to be isentropic, find: a) Specific refrigeration effect b) Volumic refrigeration effect c) Specific work of compression d) COP of the system e) Discharge Temperature. Comment on the use of LSHX by comparing the performance of the system with a SSS cycle operating between the same evaporator and condensing temperatures.
