摘　　要：针对某电子厂目前D1~D4栋宿舍楼的燃油锅炉热水系统年运行费用大。本案根据现有的空压机与冷水机组的运行情况,通过更换一台原有的YS螺杆机组为约克YEWS210-HP热泵机组以及空压机余热回收,与原有的热水锅炉系统进行经济性分析,结果表明,采用热泵机组与余热回收改造可节约运行费用约为75.56万元,本次改造的初投资价格约为127.7万元,其投资回收期约为1.64年。for the dormitory building D1 - D4 of electronic factory,its fuel boiler＇ s annual operation cost is a bit large. According to the running condition of air compressors and chillers,we replace one YS screw chiller as one York YEWS210-HP heat pump and make waste heat recovery from air compressor. And its economic analysis compares with the original hot water boiler system. The results show that this retrofit can save 755,600 RMB compared with the original hot water boiler system. And the initial investment is about 127,7000 RMB,so the payback period is about 1. 64 years.
