Abstract
It is necessary to use waste heat from thermal engines effectively for promotion of effective use of energy. Although hot water supply, space heating and so on are raised as heat directions, the amount of use is restricted in summer. However, absorption cycle driven by waste heat is useful for that purpose. The purposes of this study are to improve a coefficient of performance (COP) for water / lithium bromide absorption system, and to evaluate the feasibility for use of various waste heat sources. And, the some of results obtained by this study are as follows. (1) Energy analysis in the absorber and generator in which heat transfer and other unit operation exist was performed, and some findings were obtained. (2) In the double-effect absorption cycle, COP and exergy efficiency was calculated and the cycle evaluation was performed. (3) Some of improved cycles for double-effect absorption system were examined to clarify the advantages.
