INTAKE AIR COOLING METHOD OF ENGINE IN EXHAUST HEAT RECOVERY SYSTEM

摘要

PROBLEM TO BE SOLVED: To perform excellent cooling of compressed air to be charged into an engine without decreasing refrigerating capacity of an absorption refrigerating machine. SOLUTION: The absorption refrigerating machine is operated with cooling water from a cooling jacket of a gas engine 1 as a heat source and the compressed air is charged into the gas engine 1 from a supercharger 15. A heat exchanger 16 for cooling to cool the compressed air to be charged into the gas engine 1 from the supercharger 15 is mounted, and a working fluid taken out from an absorber 9 is charged into the heat exchanger 16 for cooling after cooling the working fluid in an evaporator 8 for cooling the compressed air. The working fluid with a higher temperature than a regenerator 6 is charged into the regenerator 6, and then heat recovered in accompany with cooling the compressed air is used as the heat source for the absorption refrigerating machine.
