An ideal vapor-compression refrigeration cycle is employed to maintain a building temperature of 23°c when the outside temperature is 37°c. the cycle operates at steady state using ammonia as the working fluid. the mass flow rate of the refrigerant is 15 kg/min. the refrigerant enters the compressor at 1.5 bar and 10 °c. the condenser pressure is 20 bar and the temperature at the condenser exit is 45 °c. determine (a) the compressor power in kw. (b) the refrigeration capacity in tons. (c) the coefficient of performance. d) the maximum theoretical coefficient of performance.
