The performance of an ammonia absorption cycle refrigerator is to be compared with that of a similar vapor-compression system. Consider an absorption system having an evaporator temperature of 10C and a condenser temperature of 50C. The generator temperature in this system is 150C. In this cycle 0.42 kJ is transferred to the ammonia in the evaporator for each kilo joule transferred from the high-temperature source to the ammonia solution in the generator. To make the comparison, assume that a reservoir is available at 150C, and that heat is transferred from this reservoir to a reversible engine that rejects heat to the surroundings at 25C. This work is then used to drive an ideal vapor-compression system with ammonia as the refrigerant. Compare the amount of refrigeration that can be achieved per kilo joule from the high-temperature source with the 0.42 kJ that can be achieved in the absorption system.
