摘　　要：太阳能辅助空气源热泵有效地将两种可再生热源复合利用,实现了太阳能与空气热能的优势互补,本文主要介绍了太阳能辅助空气源热泵的系统组成、运行模式及原理。通过对华北科技学院太阳能辅助空气源热泵系统实验台的冷凝器进出口温度、室内温度、耗电量等相关参数进行实测,与普通空气源热泵和其他供暖方式进行对比分析,重点研究了该系统的实际节能性。结果表明:太阳能辅助空气源热泵耗电量与空气源热泵基本持平,但太阳能辅助空气源热泵的制热量高于空气源热泵,其白天模式制热量为空气源热泵的1.4倍,COP是空气源热泵的1.5倍;夜间模式与空气源热泵相比,制热量为其1.2倍,COP是其1.2倍。同时太阳能辅助空气源热泵的运行费用与碳排放与传统区域供暖方式也有所降低,因此是一种节能减排的供暖方式。The solar assisted air-source heat pump（SASHP） system uses two kinds of renewable energy sources that solar and air energy,thus it will be better play their respective strengths.This paper primarily introduces the system composition,operation mode and principle of SASHP.A dedicated experimental rig was then fabricated and tested in a pilot building under the real-climate conditions in North China Institute Of Science And Technology.The essential parameters,i.e.inlet/outlet temperatures of heat-pump condenser,indoor temperature,power consumption of heat-pump compressor,were measured for characterization of the SASHP system＇s performance under different operation strategies.A feasibility study was further conducted through the comparison of such system against the conventional ASHP as well as other typical space-heating systems in that area,especially for energy saving property.Comparing to the ASHP,the delivered heat capacity of SASHP was almost 1.4 times and 1.2 times under the day-and-night operation modes,leading to the COP of 1.5 times and 1.2 times respectively.Meanwhile,the SASHP has the least operation cost and carbon emission among the conventional space-heating solutions.In addition,the SASHP has high benefits to energy conservation and environmental protection.
