Abstract

Thermodynamic analysis of an ideal vapour compression refrigeration system is done in this paper using refrigerants as CFC12, R134a and R290. This analysis is done by developing a mathematical model. A FORTRAN code is developed to solve the mathematical problems. Various parameters computed in this papers are compressor power, coefficient of performance of the system, total exergy loss, mass flow rate and exergy efficiency. The investigation is done within the evaporator range of 0°C to -20°C and condenser temperature of 30°C to 40°C. It is found from this investigation that performances of these two alternative refrigerants has slightly lower than the CFC refrigerant. So those two refrigerants can be used as a replacement for CFC12 in short term basis.
