COMPRESSION EXHAUST HEAT USING SYSTEM AND COMPRESSION EXHAUST HEAT USING METHOD OF MULTI-STAGE AIR COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a compression exhaust heat using system and a compression exhaust heat using method of a multi-stage air compressor, achieving energy saving by converting the compression exhaust heat of the multi-stage air compressor to cold to be used for cold load of an air conditioner or the like.;SOLUTION: This compression exhaust heat using system 10 includes: a multi-stage air compressor 11 having a plurality of air compressing parts 12a to 12d serially connected to each other and an air cooling means for cooling the compressed air 2 by heat exchange performed between the compressed air 2 from each air compressing part and cooling water 16; a hot water heating means 23 for heating the hot water 30 by heat exchange performed between the compressed air 2 from the air compressing parts and the hot water 30; a hot water absorbing refrigerator 33 for generating cold water 36 taking the hot water 30 heated by the hot water heating means 23 as operating hot water; and a cold load 38 using the cold water 36 generated by the hot water absorbing refrigerator 33.;COPYRIGHT: (C)2005,JPO&NCIPI
