Question:
The temperatures and pressures shown in the table were measured for a vapor-compression refrigerator that uses R-134a as the refrigerant.
The refrigerator operates between a cold region at TC and a hot region at TH. The positive-displacement compressor (piston-cylinder device) has a cylindervolume and operating speed such that it processes 1m3/min of R-134a at the inlet of the compressor.
A. Determine the minimum value of TC and the maximum value of TH.
B. Determine the coefficient of performance.
C. Determine the heat-transfer rate from the region at TC.
