Refrigerant-134a is condensed in a refrigeration system by rejecting heat to ambient air at 25°C. R-134a enters the condenser at 700 kPa and 50°C at a rate of 0.05 kg/s and leaves at the same pressure as a saturated liquid. Determine
(a) The rate of heat rejected in the condenser,
(b) The COP of this refrigeration cycle if the cooling load at these conditions is 6 kW, and (c) The rate of exergy destruction in the condenser.
