A. (a) Ice is formed at 0°C from water at 30°C. In the refrigeration system the same water is used for condenser cooling and the temperature of brine is -15°C at evaporator. Considering the system operates on Carnot refrigeration system, calculate the COP of the system. B. Refrigerant 134a enters the compressor of an ideal vapour compression refrigeration system as saturated vapour at -16°C with a volumetric flow rate of 1 m3/min. The refrigerant leaves the condenser at 36°C, 10 bar. Determine (a) the compressor power, in kW (b) the refrigerating capacity, in tonnes (c) the coefficient of performance
