摘要
自然通风是改善室内热环境的一种有效手段,量化自然通风对室内热环境的改善效果,有助于合理利用自然通风.本文通过建立室内人体舒适温度和室外气温的关系式的方法,结合China Typical Meteorological Year 2气象数据库中合肥地区典型年气象参数,对高校教室在四种工况下的4-10月份室内过热时数进行计算.并统计自然通风、关窗和机械通风对室内热环境的改善效率百分比.结果表明,长江中下游地区在6-9月份有较高的可改善过热时数,自然通风潜能较大.合理组织教室室内通风、减少教室关窗时数并辅助机械通风对改善教室室内热环境成效显著.
Natural ventilation is an effective way to improve indoor thermal environment.The quantification of the improvement effect of natural ventilation on indoor thermal environment is helpful to the rational utilization of natural ventilation.The relationship between indoor human comfort temperature and outdoor air temperature were established in this research.Combined with the China Typical Meteorological Year 2,the numbers of indoor overheating hours of university classrooms in Hefei were calculated under four working conditions in 4-10 months.Then,the percentage of improvement efficiency of natural ventilation,window closing and mechanical ventilation on indoor thermal environment were counted.The results show that great natural ventilation potential from June to September existed in the middle and lower reaches of the Yangtze River.The indoor thermal environment of the classroom could be improved by reasonably organizing the indoor ventilation,reducing the closing hours and assisting with mechanical ventilation.
