冷热电联供系统中凝结水用于制冷系统的技术经济性分析

Technical and economic analysis on condensate used for refrigeration system in CCHP system

冷热电联供系统中,蒸汽双效型溴化锂吸收式冷水机组的凝结水具有一定热量。本文以郑州某项目为例,对蒸汽凝结水作为热源水驱动新增加热水型溴化锂吸收式冷水机组实现制冷进行研究。此蒸汽凝结水回收制冷系统的静态投资为101.4万元,年售冷收入为26.1万元,年运行费用为12.0万元,静态投资回收期为7.2年。

The condensate from the steam type lithium bromide absorption water chiller still has some heat in the CCHP system.Taking aproject in Zhengzhou for example,the condensate recovery refrigeration system in which the condensate water as a heat source drives the added hot water type lithium bromide absorption water chiller is studied.In this system,the static investment is 1.014 million yuan,the annual sales income of cold is 261 000 yuan,and the annual operation cost is 120 000 yuan,so the static investment payback period is 7.2 years.
