Based on the performance analysis of the single stage, the two-stage and the double absorption heat transformer, a new ejection-absorption heat transformer is presented and analyzed in this paper. The results show that it has a simpler configuration than the double absorption heat transformer and two-stage heat transformer. The delivered useful temperature in the ejection-absorption heat transformer is higher than for a single stage heat transformer and simultaneously its system performance is raised.
