摘要
文中针对多种热源系统在居住建筑中的匹配性和节能特性等的问题,设计了太阳能辅助多热源热泵系统。在冬季进行测试实验,分别以不同的匹配方式来探究居住建筑中多热源系统收集热量和使用能耗的问题。得到太阳能在最充足的时段热能贡献率达到了31.17%,而空气源热泵的能效比也能达到3.39,最多可以使1.28t的水温升达到20℃,即整个复合系统在居住建筑中能达到很好的节能效果。
Aiming at the matching performanceand energy conservation of various heat source systems in residential buildings, this paper designed the solar-assisted multi-heat source heat pump system. In winter, this paper carry out the experiment with different matching methods to explore the problems of heat collection and energy consumption of multi-heat source system in residential buildings. The results show that the contribution rate of solar energy could can reaches 31.17% in the sufficient time, and the EER of air source heat pump can reach3.39. Besides, it can raise 1.28 tons of water temperature to 20 degrees celsius, so the whole composite system can achieve good energy-saving effect in residential buildings.
