1 what power is required to drive a reversed stirling cycle, Ask an Expert

Academics

1. What power is required to drive a reversed Stirling cycle heat pump with a high-temperature heat transfer rate of 14.0 kW over the temperature difference 30.0°C and 0.00°C, if the actual coefficient of performance is 50.0% of the ASC coefficient of performance for this unit?

2. Determine the cooling temperature and the coefficient of performance of an isenthalpic expansion cooler that expands air from 1500. psia, 70.0°F to 14.7 psia. The isentropic efficiency of the compressor is 85.0%. The mean Joule-Thomson coefficient for this process is 0.0200°F/psi.
