两种回收电厂余热热泵系统的经济性对比

摘要

Using absorption type or compression type heat pump technology to recycle the circulating water conden-sing heat in power plant.The technological process of waste heat recovery and energy saving mechanism by using heat pump system was introduced in this paper, and the comparision of economy between two pumps was showed.The calculation showed that economy of the absorption type heat pump was better, total revenue each year of the absorp-tion type heat pump was 20.65 million yuan higer than the compression type.%本文采用吸收式热泵或压缩式热泵对电厂的余热进行回收。通过具体事例对吸收式及压缩式余热节能的机理进行分析和经济性比较。计算结果表明，吸收式热泵的经济性较好，采用吸收式热泵每年获取总收益比压缩式的高2065万元。
