Summary

Absorption heat pump has features to produce high temperature energy by low temperature heat source such as hot water waste heat itself, and it is expected to be a cycle transforming waste heat to usable energy. Particularly promising is the heat pump which produces widely usable steam as high temperature energy. This paper deals with the theoretical analysis of various absorption cycles supposing reversible cycles, and discusses the COP, temperature boost and maximum performance comparing with the Carnot cycle. Then a simulation model of an actual heat pump using H2O-LiBr as the working fluid was developed to predict the performance. A route of heat source hot water from a generator to an evaporator is desirable for high performance. Preheating feed water by weak solution is available for increasing the steam generating rate in the case of steam generation by an absorption heat pump.
