摘　　要：以某热能产业园宿舍太阳能与空气源热泵定时供热水系统为研究对象。通过对系统的现场测试,确定系统控制方案所存在的缺陷,对系统控制方案进行优化,提出逐时温度比较控制方案。结果发现,与原控制方案相比,系统采用优化控制方案时,空气源热泵能耗减少15.1%,太阳能集热器集热量增加26.7%,总能耗减少12.2%。建议采用优化后的控制方案。This paper takes solar and air source heat pump combined hot water supply system as the object, whichlocated in a thermal industrial park dormitory. The defect in the control scheme is determined through field test, and thehourly temperature comparison control scheme is presented through optimizing the original control scheme. The resultsshow that compared with the original system control scheme, the energy consumption of air source heat pump reduces by15.1% and the heat of the solar collector increases by 26.7% when the optimized control scheme is adopted, the totalenergy consumption reduces by 12.2%. So the optimized control scheme is recommended.
