秦岭南麓服务区建筑热环境及被动式技术改善研究

Improvement of Building Thermal Environment and Passive Technology in Service Area at the Southern Foot of Qinling Mountains

为了研究秦岭南麓服务区建筑热环境问题,通过调研走访秦岭南麓所有服务区,经过各方面对比,最终以秦岭南麓的秦岭服务区为研究对象,对服务区中休息区的室内温湿度、风速和黑球温度进行24 h实测,结果分析表明:秦岭南麓服务区存在围护结构热工性能差、湿度较大、自然通风较差、温差较大等问题。通过相应参考文献提出针对秦岭服务区适宜的被动式技术设计策略,并通过Ecotect软件对秦岭南麓地区进行风玫瑰图分析,采用SPSS软件对不同工况进行正交排列组合,再以DesignBuilding软件对5组最优的工况进行模拟,最终选取能耗最低的工况为最优改善技术,以期为寒冷地区山区服务区设计建造提供参考。

In order to study the thermal environment of buildings in the service area at the southern foot of the Qinling Mountains, all the service areas at the southern foot of the Qinling Mountains were visited through investigation and comparison. The Qinling service area at the southern foot of the Qinling Mountains was taken as the research object, and the indoor temperature, humidity, wind speed and black ball temperature in the rest area of the service area were measured for 24 hours. The results showed that, in the service area at the southern foot of Qinling Mountains, there are some problems such as poor thermal performance, high humidity, poor natural ventilation and large temperature difference of the envelope structure. The appropriate passive technical design strategy for Qinling service area was proposed through the relevant references. The wind rose diagram analysis of the southern foothills of Qinling was conducted by Ecotect software, the orthogonal arrangement and combination of different working conditions were conducted by SPSS software, and the five groups of optimal working conditions were simulated by DesignBuilding software. The condition with the lowest energy consumption is selected as the optimal improvement technology in order to provide reference for the design and construction of cold mountainous area service area.
