摘要
本文以三元非共沸混合工质R407C对传统工质HCFC22进行了替代,搭建了地源热泵系统实验台。考虑到在地源热泵运行时,地下土壤温度会因运行时间和冬夏季节的不同而发生变化,造成热泵的各种不同运行工况。为全面反映热泵的运行状态制订了测试方案,并对测试数据进行了整理和分析。该热泵系统在加热与制冷运行模式下COP均可达到3．6以上。
In this paper, a ground source heat pump in which HCFC22 was replaced by non-zeotropic mixture R407C was designed and manufactured. The heat pump was tested in different conditions to simulate the variation of ground temperature and the season effects on the performance. In typical running conditions, the COP of the system could reach above 3.6 for both heating and cooling modes.
