A refrigeration system is working on vapour compression cycle using R134a as refrigerant. The objective is to keep the refrigerated space at temperature of 243K. The vapours enter the compressor at 0.6 bar and at 239K and after compression leaves at 12 bar and 338K. The condenser is water cooled, in which water is supplied at 291 K at mass flow rate of 15 Kg/hr. and leaves at 299K. The refrigerant leaves the condenser temperature of 315K after rejecting heat. The compressor is not perfectly insulated and it absorbs 450 J/sec of heat from the surrounding. Analyze the refrigerator by determining
