A vapor compression refrigeration system operates on the ideal vapor compression cycle. The refrigerant enters the compressor at -10°C and leaves the condenser at 40°C. The compressor has an isentropic efficiency of 80%. The condenser rejects heat at a rate of 50 kW, and the evaporator operates at a temperature of -20°C. Determine the compressor power input and the coefficient of performance (COP) of the refrigeration system. Assume the refrigerant behaves as an ideal gas and neglects any pressure drops in the system.
