A numerical and experimental study of a dual-function solar collector integrated with building in passive space heating mode

A newly designed solar collector named dual-function solar collector is proposed.The dual-function solar collector integrated with building can perform in two different modes:working as a passive space heating collector in cold sunny days such as in winter,or working as a facade water heating collector in hot days such as in summer.An experimental study has been carried out to investigate the performance of the novel system in space heating mode,whilst,the dynamic numerical model has been established and va...     

An improved approach for the application of Trombe wall system to building construction with selective thermo-insulation façades

An improved Trombe wall is proposed to adapt to building construction with selective thermo-insulation facades （internal and cavity wall insulation, but not external wall insulation system）. The case study is conducted in Xining, Capital city of Qinghai province in China, where the general building fa- cades are mostly selective thermo-insulation facades to fight against the severe cold. A numerical analysis is undertaken to show the effects on the improvement of the building＇s thermal environment by comparing the improved Trombe wall system with the classical Trombe wall system. The operating efficiency of the improved Trombe wall can be up to 33.85%, an increase of 56%. The results show that the improved Trombe wall works more effectively than the classical Trombe wall system in utilizing solar energy for the sample building.     

高原严寒地区观察哨楼连续式太阳能供暖系统

针对高原严寒地区边防执勤哨楼燃料缺乏，无法正常供暖的实际困难，提出了将被动式太阳房技术、主动式太阳能集热技术、相变材料蓄热技术集为一体的连续式太阳能供暖系统，并对该系统进行了研究。使得单纯利用太阳能向室内连续供暖成为可能。通过在高原严寒地区边防执勤哨楼的应用，表明该系统能够实现向室内不间断供暖。
