重庆地区地表水源热泵示范项目能效分析 与评价 ☆ 北京建筑大学 王欣 李德英 摘要：本文以重庆地区7 个地表水源热泵系统工程为案例，对地表水源热泵系统制冷和 制热能效比进行分析与评价，为典型项目提高能效提出解决方案。结果表明：重庆地表水源 热泵系统制冷（热）期间，在满足室内温湿度要求的前提下，冬、夏季机组COP 分布在4.2-5、 4.8-6.1 范围内；系统EER 在2.3-3.9、2.7-4.2 之间。江水比湖、河水更适宜作冷热源， 夏季机组COP、系统EER 均明显高于冬季。平均常规能源替代量为924.1 吨/年，CO2、SO2、 粉尘减排量分别为2278.7 吨/年、18.2 吨/年、9.1 吨/年，平均静态投资回收期为5.9 年， 地表水源热泵寿命周期一般为20 年，有明显的经济效益。根据《可再生能源建筑应用工程 评价标准》中的评分细则多数系统EER 处于2 级以下，冬季热源侧换热温差普遍偏小，应模 拟变工况运行能耗，以最优换热温差运行。 关键词：重庆地区 地表水源热泵 性能系数 能效比 静态回收期 Energy Efficiency Analysis and Assessment of Surface Water Source Heat Pump Demonstration Project in Chongqing area By Wang Xin★and Li Deying Abstract In this paper, seven surface water source heat pump system in Chongqing area as a case study, the surface water source heat pump system cooling and heating energy efficiency analysis and evaluation for the typical project to improve energy efficiency solutions. The results show that during the cooling (heating) period of surface water source heat pump system in Chongqing, under the premise of meeting the requirements of indoor temperature and humidity, the COP of winter and summer units are distributed in the range of 4.2-5.4 and 4.8-6.1. The system EER is between 2.3-3.9 and 2.7-4.2. River water is more suitable than the lake, river water for cold and heat sources, summer unit COP and system EER were significantly higher than in winter. The average regular energy replacement is 924.1 tons / year.CO2, SO2 and dust emission reductions are 2278.7 tons / year, 18.2 tons / year and 9.1 tons / year respectively. The average static investment recovery period is 5.9 years. The surface water source heat pump life cycle Generally 20 years, there are obvious economic benefi
