摘要:

为评估北京农村清洁能源供暖项目中空气源热泵供暖系统的实际运行效果,选取15个典型住宅空气源热泵供暖系统,进行了供暖期监测。介绍了项目的概况,在确定合理监测方案的基础上,对比了各项目的监测结果,分析了各种因素对系统性能的影响。结果表明,空气源热泵系统在农村的实际应用效果较好,供暖末端形式显著影响系统COP,变频压缩技术有助于系统COP的提升,室外温度较相对湿度对系统COP的影响更显著。

Abstract:

In order to evaluate the actual operation effect of the air-source heat pump heating systems applied to rural residences of clean energy heating projects in Beijing, selects fifteen typical systems installed in rural housing for continual monitoring in heating period. Presents the general profile of the projects, based on reasonable monitoring scheme, compares the monitoring results of each project, and analyses the influence of each factor on system performance. The result shows that the practical application of air-source heat pump system in rural areas is favorable, the terminal heating form significantly affects system COP, the frequency conversion compression technique contributes to the enhancement of system COP, and the outdoor air temperature has more obvious effect on the system COP than the relative humidity.
