Question

Air enters the compressor of a gas refrigeration cycle at -10°C and is compressed from 200°C and is compressed from 250 kPa to 850 kPa. The high pressure air is then cooled to 0°C by transferring energy to the surroundings and then to -35°C with an internal heat exchanger before it enters the turbine. Calculate the minimum possible temperature of the air leaving the turbine, the coefficient of performance, and the mass flux for 8 tons of refrigeration. Assume ideal conditions. [MO1, MO2, MO3]
