An ammonia absorption refrigeration cycle requires 2500 Btu/lbm heat transfer in the generator.Saturated vapor leaves the generator at 110 F and saturated vapor leaves the evaporator at 40 F.
a. Determine the performance of the refrigerator by calculating the ratio of the heat transfer rate in the evaporator to that in the generator.
b. If this were a regular vapor-compression cycle with a compressor instead of the absorption process, what would the COP be?
c. Discuss the pros and cons for both the ammonia absorption and vapor-compression
cycles.
