In the diagram of a refrigeration cycle, a liquid-vapor separation unit (separator) is used to separate the gas and liquid. The system uses refrigerant-134a as the working fluid and the cooling capacity is 30 kW. All relevant parameters are given on the diagram. a) Show the cycle on a T-s diagram, b) Determine the mass flow rates of each compressor, c) Find the power of the compressors, d) What is the COP of the system? x3 = x5 = 0, x7 = x1 = 1 and the compressors are isentropic
