A vapour compression refrigeration plant using R12 has saturation temperatures in the evaporator and condenser of -20°C and 35°C respectively. The R12 leaving the condenser is undercooled by 5°C and leaving the evaporator it is superheated by 15°C. The R12 circulates at 10kg/m. Calculate: (a). the dryness fraction of the R12 at the evaporator inlet (b). the cooling load in kW (c). the rate of work done on the R12 in the compressor (d). the plant capacity
