基于全年综合能效评定方法的空气源热泵热水系统性能测试研究

Performance of Air Source Heat Pump Domestic Hot Water System under Seasonal Energy Efficiency Assessment

为研究空气源热泵热水系统的实际运行能耗情况,基于空气源热泵热水系统全年综合能效评定方法,对上海地区某酒店客房采用空气源热泵作为热源的生活热水系统的制热量、用电量、能效比(COP)等重要参数进行全年实测和分析。测试结果表明:空气源热泵的全年综合能效比(SEER)为3.92,与名义工况下能效比(COP)4.4相差较大,差值约为10.9%。整个热水系统的SEER除了受到空气源热泵自身性能的影响,还受到系统的选型、控制策略等因素影响。基于全年综合运行工况,对空气源热泵以及整个热水系统的实际能效比进行分析和评价,具有一定的参考和实际应用价值。

Energy consumption of air source heat pump domestic hot water system in a hotel in Shanghai was studied with seasonal energy efficiency assessment, and parameters including heating capacity, power consumption and coefficient of performance（COP） were measured and analyzed. The results show that the seasonal energy efficiency ratio（SEER） of the air source heat pump is 3.92, which is larger than energy efficiency ratio under nominal conditions（4.4） with difference of 10.9%. SEER of the whole domestic hot water system is affected by air source heat pump and system selection together with control strategy. The actual energy efficiency ratio of the air source heat pump and the whole domestic hot water system was analyzed and evaluated based on operation conditions in the whole year, which provides guidance for related applications.
