A vapor-compression refrigeration cycle operates at steady state with Refrigerant 134a as the working fluid. Saturated vapor enters the compressor at 2 bar, and saturated liquid exits the condenser at 10 bar.
A vapor-compression refrigeration cycle operates at steady state with Refrigerant 134a as the working fluid. Saturated vapor enters the compressor at 2 bar, and saturated liquid exits the condenser at 10 bar. The isentropic compressor efficiency is 80%. The mass flow rate of refrigerant is 7 kg/min.
Determine:
(a) the compressor power, in kW.
(b) the refrigeration capacity, in tons.
(c) the coefficient of performance.
