摘要:

以遵化市某住宅小区地下水地源热泵系统作为研究对象,对其冬季运行工况进行了长期测试,分析了机组的运行情况、节能效益、环境效益和经济效益。结果表明:机组运行稳定,供热效果良好,系统性能系数可达1级标准,但系统耗电输热比较大,水泵效率偏低;与常规供暖系统相比,具有明显的节能效益、环境效益和经济效益。

Abstract:

Taking the groundwater-source heat pump system of a residential community in Zunhua City as a research object, tests the winter operation conditions of the system for a long time, and analyses the operation status, energy saving benefit, environmental benefit and economic benefit of the units. The results show that the unit runs stably with a good heating effect, the system coefficient of performance (COP) can reach the level 1 standard, but the electricity consumption to transferred heat quantity ratio (EHR) is high and the pump efficiency is low. Compared with the conventional heating system, the groundwater-source heat pump system has obvious energy saving benefit, environmental benefit and economic benefit.
