Air within a piston–cylinder assembly undergoes a Stirling
refrigeration cycle, which is the reverse of the Stirling power
cycle introduced in Sec. 9.8.4. At the beginning of the isothermal
compression, the pressure and temperature are 100 kPa and 350 K,
respectively. The compression ratio is 7, and the temperature
during the isothermal expansion is 150 K.
a) heat transfer for the isothermal compression, in kJ per kg of
air.
b) net work for the cycle, in kJ per kg of air.
c) coefficient of performance.
