夏热冬暖地区商场冬季室内热舒适研究
Field study on indoor thermal comfort of shopping malls in hot summer and warm winter zone
摘要：
以广州某大型综合商场为研究对象，采用问卷调查和现场测试相结合的方式，对商场冬季室内热舒适性进行了调查研究，并对调查测试结果进行了统计回归分析。研究结果显示：商场冬季室内实测热中性温度为19.4 ℃，90%满意度热舒适温度范围为16.1~22.7 ℃；而根据PMV计算得到的室内热中性温度为16.8 ℃，90%满意度热舒适温度范围为13.3~20.4 ℃；PMV模型预测的热感觉比现场问卷调查得到的平均热感觉MTS要高，与实际感觉存在一定偏差。基于实测热舒适数据，进一步分析了室内热中性温度与室外空气温度的相关性，确立了商场冬季室内热中性温度与室外空气温度的近似线性关系，建立了商场冬季室内热舒适气候适应性模型。
Abstract：
Taking a large integrated shopping mall in Guangzhou as the research object, carries out the indoor thermal comfort research through the questionnaires and field measurement in winter. Conducts a statistical regression analysis on the survey data. The results show that the measured thermal neutral temperature of the mall in winter is 19.4 ℃, and the thermal comfort temperature which meets a satisfaction degree of 90% ranges from 16.1 ℃ to 22.7 ℃. Meanwhile, the indoor thermal neutral temperature calculated by PMV model is 16.8 ℃, and the thermal comfort temperature which meets a satisfaction degree of 90% ranges from 13.3 ℃ to 20.4 ℃.The thermal sensation predicted by the PMV model is much higher than the actual thermal feeling. Based on the survey data, analyses the correlation between the indoor thermal neutral temperature and outdoor air temperature, and establishes the approximate linear relationship between the mall’s indoor thermal neutral temperature and outdoor air temperature. Sets up a winter thermal comfort climate adaptation model for the shopping mall.
