| 摘 要： | 为了充分利用炎热季节和过渡季节的太阳能又确保寒冷季节热水需求量,并避免单独应用土壤源热泵时存在的缺陷,结合广西大学23号研究生宿舍楼热水工程(示范项目),阐述了土壤源/直膨式太阳能双热源热泵系统及自流式供热水系统的创新设计理念及设计方法。分析结果表明:双热源热泵系统比土壤源热泵系统每年可节电3 420 kW.h,并减少从地下土壤吸热量106 538 kW;自流式供热水系统比循环式一年可以节电5 475 kW.h。

| Abstract: | In order to take full advantage of the solar energy in hot season and the transitional sea-sons and to ensure the demand of hot water at the cold season, and to avoid the defects of ground source heat pump used alone, the design methods of the ground source/direct expansion type solar dual heat source heat pump system and the gravity-type hot water system are described based on a demonstration project that is hot water system of No. 23 dormitory of Guangxi University. The analysis shows that com-pared with ground source heat pump system, the dual heat source heat pump system can annually save |
