重庆与武汉冬季托幼建筑中幼儿热舒适研究

Children's thermal comfort in kindergarten buildings of Chongqing and Wuhan in winter

针对目前夏热冬冷地区托幼建筑冬季室内热环境现状,对重庆和武汉两地进行了调研与实测分析,从而获得幼儿热环境评价指标。以修正幼儿代谢率的方法为基础,计算得到了幼儿热感觉预测平均评价指标PMV值;以幼儿实际热感觉对应的幼儿生理、行为表现为依据,得到了幼儿的实际热感觉投票TSV值。对两地PMV值和TSV值进行了对比分析。结果显示:两地幼儿的PMV与TSV的差值基本维持在0.2左右;影响幼儿热舒适的主要因素是幼儿的活动水平和教师对室内热环境的主观调控。

In view of thermal environment in kindergarten buildings in hot summer and cold winter zone in winter, conducts a survey and field measurement in two typical cities of Chongqing and Wuhan and obtains the evaluation index of thermal environment for children. Based on the method of metabolic rate correction, calculates the predicted mean vote （PMV） of children. According to the physiological and behavioral expressions of the children＇s actual thermal sensation, obtains the thermal sensation vote （TSV）. Compares PMV with TSV of children in the two cities. The results show that the differences between PMV and TSV are about 0.2. The main factors influencing children thermal comfort arc the children＇s activity frequency and tcachcr＇s subjective control on the indoor thermal environment.
