Question
Data for steady-state operation of a vapor-compression refrigeration cycle with Refrigerant 134a as the
working fluid are given in the table below. State 1 is at the compressor inlet. The cooling capacity (i.e the
rate at which heat is removed from the cooled space) is 4.6 tons. 1 ton of refrigeration is equivalent to
211 kJ/min. Ignoring heat transfer between the compressor and its surroundings, sketch the ?-? diagram
of the cycle and determine
a) the mass flow rate of the refrigerant, in kg/min.
b) the isentropic compressor efficiency.
c) the coefficient of performance.
