摘要
结合辅助热源应用的空气源热泵多能互补系统是解决我国北方地区冬季供暖的有效途径,可以显著改善热泵系统的综合能效。本文编制专门的软件对太阳能-空气源热泵多能互补系统进行分析,根据内置室外逐时干球温度、室外逐时水平地面太阳辐射量、建筑物逐时热负荷、热泵性能、出水温度和水箱、水泵等相关参数计算太阳能集热器表面最佳倾角、太阳能-空气源热泵多能互补系统的供暖季节逐时能耗、经济性及节能减排效益等,并对北京某居民建筑采用的太阳能-空气源热泵多能互补系统进行分析。
The air source heat pump multi-energy complementary system combined with auxiliary heat source,which can significantly improve the comprehensive energy efficiency of the heat pump system,is an effective way to solve heating problems in northern China in winter.The specific software for analyzing the solar-air source heat pump(SASHP)multi-energy complementary system is developed.Using built-in hourly outdoor dry bulb temperature,hourly solar radiation of horizontal ground,hourly heat load of building,performance of heat pump,outlet water temperature,as well as the parameter of water tank and water pump,the software can calculate the best angle of heat collector surface and energy consumption of SASHP multi-energy complementary system in heating season,as well as economy,energy-saving and emission reduction.In addition,a case analysis of SASHP multi-energy complementary system applied to Beijing residential buildings is carried out.
