The zeolite 13X-H 2 O couple is used to recover energy and minimize irreversibility effects. A comparison of the obtained results for a simple adsorption heat transformer with ejector is carried out. It is observed that the ejection system shows a lower total of irreversibility than the simple system. The simulation results show that the exergetic performance and efficiency of a cycle of an adsorption heat transformer with ejector are important. It is 12 and 10 %,
