The Application Of Transpired Solar Collector With Punching Corrugated Plate In The Rural Buildings

In order to alleviate the energy crisis, promote the use and development of renewable energy, reduce winter heating energy consumption in rural buildings and improve the indoor comfort in non- heating rural buildings, through the combination of data research, experimental research and simulation research, I studied the heating effect of transpired solar collector with punching corrugated plate in rural buildings of different types in different areas.Firstly, in order to improve the evaluation system of solar collector's heating effect, I proposed several evaluation factors: guarantee hours, instantaneous guarantee percentage, collector operating hours, run-time instantaneous guarantee percentage, and simulate the effect of building thermal performance and meteorological parameters to building heat consumption per unit area, the amount of collector per unit area, solar fraction, solar heating guarantee hours, instantaneous guarantee percentage, collector operating hours, run-time instantaneous guarantee percentage. The results show that the thermal performance of external walls has the maximum effect on heating effect. It's necessary to strengthen the insulation properties of external walls when installation. I also simulate and analyze the heating effect of collectors installed on different faces of the walls of experimental construction, the results show that only on the south face is appropriate for installation.Secondly, I collect the building type and thermal parameters of the extreme cold area, cold area and hot summer and cold winter area in the 35 typical rural residences, and then simulate and calculate the heating effect in heating season of the buildings installed the transpired solar collector with punching corrugated plate. The results show that the optimization of the buildings thermal performance has a significant effect on improving the heating factors. Different types of building structures and south window to wall ratio affect the installation area of collector, and also have a big influence on heating effect.Thirdly, using the typical annual meteorological parameters of the extreme cold area, cold area and hot summer and cold winter area in 25 provinces, I simulate and calculate the heating effect of a new two-floor rural building used the transpired solar collector with punching corrugated plate, and map the area distribution of building heat consumption per unit area, the amount of collector per unit area, solar fraction, solar heating guarantee hours, instantaneous guarantee percentage, collector operating hours, run-time instantaneous guarantee percentage. Analyze the application effect of different areas and supply suggestions for usage and installation in different area. The research shows that the use effect is great in Tibet, Qinghai, Ningxia, etc. It's suitable for large scale use.I develop the heating factors calculation program and interface of the transpired solar collector with punching corrugated plate, using this software, you can predict the rural buildings' heating effect can be achieved with the installation of solar collector, and provide the basis for building design and collector selection.Finally, according to the results of research and analysis, I give a number of opinions on the installation and use of transpired solar collector with punching corrugated plate.
