关于农村住宅冬季热环境与节能改造的分析研究

Research on Indoor Thermal Environment of Rural Residences in Winter and Energy-saving Retrofit

本文采用实地调查测量以及应用DeST与TRNSYS软件模拟分析相结合的方法,对陕西华县的农村建筑概况、供暖方式和建筑室内热环境进行了分析研究,并对建筑围护结构进行节能改造前后室内达到不同供暖设计温度时的热负荷进行了模拟分析,为今后通过改变建筑材料及添加保温材料来达到降低能耗及改善室内热环境、提高农村建筑热舒适性、合理设定冬季室内采暖计算温度提供了参考依据。在此基础上,简单对比分析了2种软件模拟结果存在差异的原因。

In this paper, based on the combination of field survey and simulation with software of DeST and TRNSYS,the research on building condition, heating methods and indoor thermal environment in Hua County in Shannxi was carried out. This is followed by the simulation of heating loads of ordinary and energy-saving buildings under different heating design temperatures. As a result, the reference for reducing the energy consumption and improving indoor thermal environment by changing the building envelope materials and adding insulation materials was provided, as well as for the improvement of indoor thermal comfort of rural residence and determination of reasonable winter heating indoor design temperature. Besides, the reasons for different simulated results with software of DeST and TRNSYS were discussed.
