Measurement and analysis of groundwater-source heat pump heating system in a community of Zunhua City

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.
