What should be the percent increase of COPof a standard vapor compression refrigerationsystem when expansion of R-12 is isentropicinstead of isenthalpic process? Evaporator andcondenser temperature limits are -10°C and30°C respectively.
Exampie Air conditioning unit uses Freon R-22 for conditioned office at 25 C. The evaporating temperature is 17 C and the condensing temperature is 47 C. The compressor is reciprocating and single acting with number of cylinders of 4, volumetric efficiency of 0.9, number of revolution is 900 rpm cylinder dimensions of L/D is 1.25. If the compressor power is 3 kW and mechanical efficiency of 0.9, estimate the followings: the refrigerant mass flow rate in kg/min, refrigeration capacity in TR, cylinder dimensions, condenser heat load, coefficient of performance and relative efficiency. and

A R22 refrigeration system is used to operate between 45degC and -30degC. The total cooling capacity is 350 kW. a. What is the ideal COP of the system? b. What is the heat rejected by the system? c. What is the total power consumed by the system? There are several steps made to improve the performance of the system. What happens to the COP, heat rejected and power consumed by the system when: d. For the same evaporator and condenser pressure, the temperature at the entrance of the compressor is -20degC, and the inlet to the expansion valve is subcooled by 5degC. Due to the wide temperature gap, it is decided to use a two-stage refrigeration system using flash gas removal and optimal intercooling operation in a flash chamber. What happens to the COP, heat rejected and power consumed by the system when: e. Having a low pressure and high-pressure compression. f. Two evaporators and two compressors, with the lower temperature evaporator having a cooling capacity of 225 kW. Notes: The…
