福建南平高层住宅夏季室内热环境与通风实测分析

Measure and Analysis High-rise Residential Indoor Thermal Environment and Ventilation in Summer in Nanping,Fujian

通过对福建南平某一高层住宅夏季室内热环境与通风实测,全面评价了该住宅夏季室内热环境的状况,在此基础上讨论了通风对室内热舒适的影响。实测分析结果表明:(1)该住宅在夏季时段室内风速较小,室内风速大于等于0.2m/s(即一般情况下的风感阈值)的情况,无论主卧室或者客厅均达不到50%;(2)该住宅夏季时段在完全自然通风条件下,室内的PMV指标接近2.0,为热不舒适状况;(3)通过计算,加强住宅室内通风有利于改善该住宅室内热舒适状况,但仍未达到PMV在±1的范围内,因此试图仅采用自然通风手段达到住宅室内热舒适是不可行的,南平市的该住宅夏季须使用空调才能达到室内热舒适。

After a detailed experimental investigating a high-rise residential indoor thermal environment and ventilation in summer 2009,in Nanping City,Fujian Province,the investigation comprehensively assess indoor thermal environment in the high-rise resident.Based on the investigation,the article discusses the effect of ventilation upon indoor comfort.The results show： 1.Indoor airflow speed in the resident is low.Neither main bedroom and living room can reach the case of indoor airflow speed upper than 0.2m/s more than 50%,that is the airflow speed threshold value people can feel.2.In completely natural ventilation conditions in summer,the resident indoor PMV index about 2.0,that means a thermal uncomfortable condition.3.Though calculating,enhanced the resident＇s ventilation would improve indoor thermal comfort,but it still can＇t lead PMV within ±1.So reaching the resident＇s indoor thermal comfort just used natural ventilation method is impossible.The resident in Nanping City should use air-condition equipments can reach indoor thermal comfort.
