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。
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.
