Abstract
Two configurations of power/cooling cycle with ammonia-water mixture are evaluated. At first, an ammonia-absorption hybrid cycle (AAH), which is one of the simplest configurations, is evaluated on temperature entropy diagram to introduce the insight for enhancement. The other configuration, which was proposed by Goswami, is also evaluated. It is a candidate for an enhanced in producing power. The multi-objective optimization for net-work output, refrigerating capacity and total thermal conductance are carried out to derive the pareto front. The optimization is carried out by epsilon-constraint method. The results show that T-S diagram is a good tool for derive the enhancement. Goswami cycle has about quarter cooling capacity while 123.8% net output power comparing with AAH.
