Field measurement of air-source heat pump heating systems for rural residences of Beijing

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.
