The mass flow rate of R-134a in a vapor-compression refrigeration cycle is 6 kg/min
The mass flow rate of R-134a in a vapor-compression refrigeration cycle is 6 kg/min. At the inlet of the compressor, R-134a is at -10°C, 150 kPa. The pressure at the compressor exit is 600 kPa. The compressor has an isentropic efficiency of 67%. The refrigerant leaves the condenser at 20°C. Neglect any pressure drops in the condenser, the evaporator, and pipes. Assume an adiabatic compressor. (a)draw the cycle and the T-s diagram of the cycle. Also find: (b)the coefficient of the performance...

250kPa. Refrigerant condenser
comes out as saturated liquid and works at 700kPa pressure
reduced to the pressure of the evaporation chamber. Meanwhile, some
of the refrigerant evaporates and is mixed with the fluid from the
low pressure compressor. The mixture is then
