a vapor-compression refrigeration system uses refrigerant 134a as the working fluid. The refrigerant enters the compressor at 2.4bar, 0C, with a volumetric flow rate of 0.6m^3/min. Compresion is adiabatic to 9 bar, 60C ,and saturated liquid exits the condenser at 9 bar. Draw the (T-S) diagram of the cycle and determine:
A)The power input to the compressor in KW.
B) The cooling capacity of the system, in tons.
C) The coefficient of performance of the system.
D) The isentropic compressor efficiency.
