Effect of evaporator design pressure on dual-pressure absorption heat pump performance.

Author(s) : PALMER S. C., SHELTON S. V.

Summary

A numerical analysis of the effect of evaporator pressure on performance is carried out for several direct-fired dual-pressure ammonia/water absorption heat pumps utilizing a precooler in the refrigerant loop. The evaporator pressure which provides the maximum COP is the "optimum evaporator pressure". The study shows that the evaporator pressure for dual-pressure absorption cycles should be optimized to find the maximum COP. At the maximum COP, the temperature differences at each end of the precooler are equal to each other and the minimum cycle pinch point for all cycles considered.
