摘要
燃煤电厂的冷凝热的利用不仅可以回收热量还可以节约水量.选择哈尔滨、呼和浩特、太原、北京、西安5个冬季采暖城市的住宅小区作为热用户,对电驱动热泵和吸收式热泵作为火电厂冷凝热的回收系统进行经济技术分析.分析结果表明度日数越大,热泵回收的可行性越高;吸收式热泵经济效益好于电驱动热泵.最后给出了夏季回收冷凝热的思路.
Utilization of condensing heat recovers not only heat but also water. Five Chinese cities,that are Harbin,Hohhot,Taiyuan,Beijing,Xi＇an are selected to be the object of study,and a residence area is heat consumer,techno-economic analysis on utilization of surplus heat of condensing heat in fossil fuel power plants is done for compression-type heat pump and absorption-type heat pump respectively. The result shows that the more degree day,the recovery is more feasible and absorption-type heat pump is more economical than compression-type heat pump to recover the condensing heat. Lastly,the idea on recovery of condensing heat in summer is given.
