夏热冬冷地区地表水源热泵住宅供热应用分析

Application of Surface Water Source Heat Pump for Residential Heating in Hot Summer and Cold Winter Area

地表水源热泵系统因其良好的性能及属于可再生能源受到行业的关注与应用。目前,地表水源热泵项目多应用于大型公共建筑,而应用于小型住宅的较少。为分析小型地表水源热泵在住宅中的应用,本文以夏热冬冷地区一栋小型住宅为例分析地表水源热泵的供热性能。通过实际数据分析,结果表明,地表水温度较室外空气稳定,是良好的冷热源。热泵机组供热平均COP为3.25。系统的平均输送能耗比为12.4%。

Surface water source heat pump system is concerned and applied by the industry due to its good performance and being a renewable energy source.At present,the surface water source heat pump project is mostly used in largescale public buildings,but less used in small houses.In order to analyze the application of small surface water source heat pumps in residential buildings,this paper analyzes the heating performance of surface water source heat pump by taking a small house in hot summer and cold winter area as an example.Through the actual data analysis,the results show that the surface water temperature is stable than the outdoor air and is a good source of cold and heat.The average heat pump heat pump COP is 3.25.The average system transmission energy consumption ratio is 12.4%.
