摘要
本文主要研究了河水源热泵的运行性能,并在上海一校园的绿色能源实验室搭建了河水源热泵系统实验台。首先对河水水质进行了测试,测试结果显示水源热泵的水源侧应选择间接换热方式。本文设计了水源热泵系统并搭建了测试系统,对系统的冬夏季运行工况进行了测试。实验结果表明:在典型夏天工况,系统COP为5.2;在典型冬天工况,系统COP为3.1。
The operation performances of water-to-water heat pumps using river water as the heat source and sink were investigated. The system test-bed was constructed in Sino-Italy green energy laboratory in a campus in Shanghai. An initial experiment was carried out on the quality of river water. The results indicate that the water should not go through the heat pump directly. The river water source heat pump system and performance testing system were designed, and then the system performances in a typical summer day and a typical winter day were investigated and analyzed. The results indicate that the system COP in the typical summer day and COP in the typical winter day are 5.2 and 3.1, respectively.
