基于TRNSYS的装配式异质复合墙体日光温室建筑参数优化
Building parameter optimization of solar greenhouse with assembled heterogeneous composite wall based on TRNSYS
摘要
Abstract
In order to optimize the construction parameters of the solar greenhouse with assembled heterogeneous composite wall,a greenhouse model was established using TRNSYS(Transient system simulation program),and the measured data of consecutive cloudy and consecutive sunny days were used to validate the model.The model was utilized to analyze the effects of changes in the greenhouse ridge height,height of the north wall and horizontal projection width of the rear roof on the indoor temperature,north wall temperature,north wall temperature and construction cost.The results showed that:The indoor temperature,north wall temperature and total construction cost increased with increasing ridge height.When the ridge height was>5.3 m,the increase in mean indoor temperature and mean north wall temperature decreased significantly,while the construction cost still increased;The indoor temperature,north wall temperature and total construction cost increased with increasing height of the north wall,and the better results for indoor temperature and north wall temperature were achieved at the height of the north wall of 3.7 m.Continuing to increase the height of the north wall did not have a significant effect on the temperature enhancement;When the horizontal projection width of the rear roof was 1.8 m,the elevation angle of the rear roof of the greenhouse was 46°,and the angle of the light roof is 27°,which met the lighting requirements in the greenhouse.In summary,the best balance between the indoor thermal performance and construction cost can be achieved when the ridge height of the greenhouse is 5.3 m,the height of the north wall is 3.7 m,and the horizontal projection width of the rear roof is 1.8 m.At this point,the total construction cost of the greenhouse is 221.5 thousand,and the construction cost of each square meter is about 230 yuan.关键词
