豫南乡镇小学室内热环境分析及优化策略研究

Analysis on Indoor Thermal Environment and Corresponding Optimization Strategies in Rural Primary Schools in Southern Henan

在出现炎热或寒冷天气时,豫南乡镇既有小学普遍出现室内舒适度下降的现象。不尽如人意的热环境质量不仅影响学生的身心健康和学习效率,并且能耗损失极大。文章以南阳市霍口小学为研究对象,通过对现场温湿度进行测试及模拟验证,对该教学楼的室内热环境进行量化分析,发现其室内热环境品质低下与门窗气密性差、围护结构传热系数较大等因素密切相关。基于分析结果,文章从建筑墙体、门窗、屋顶构造方面提出优化策略,并使用Design Builder模拟软件验证优化方案的可行性,为提升和优化该地区乡镇小学室内热环境质量提供参考。

During hot or cold weather,there is a general decline in indoor comfort in the classrooms of the existing rural primary schools in southern Henan.The poor quality of the thermal environment not only affects students’physical and mental health and learning efficiency,but also leads to significant energy losses.This paper takes Huokou Primary School in Nanyang City as the research object,and conducts quantitative analysis on the indoor thermal environment of the teaching building by measuring,simulating and verifying the on-site temperature and humidity.It is found that the poor thermal environment is closely related with the poor airtightness of doors and windows,and the large heat transfer coefficient of the enclosure structure.Based on the analysis results,the paper proposes optimization strategies in terms of building walls,doors and windows,and roof construction,and uses Design Builder simulation software to verify the feasibility of the optimization scheme.It provides a reference for improving and optimizing the indoor thermal environment quality of the primary school in the township in this area.
