Consider a Brayton refrigeration cycle with a regenerative heat exchanger. Air with a volumetric flow rate of 2500 ft³/min enters the compressor at 480°R, 15 lbf/in² and is compressed to 40 lbf/in². Compressed air enters the regenerative heat exchanger at 540°R and is cooled to 480°R before entering the turbine. The compressor and turbine each have isentropic efficiencies of 88%.
