夏热冬暖地区典型城市某小学热环境特点研究

A Study on the Thermal Environment Characteristics of a Primary School in a Typical City in Hot Summer and Warm Winter Area

为了解夏热冬暖地区小学教室的室内热环境特点,选取该气候区代表城市广州的某一典型小学作为研究对象,对该学校教室的室内热环境进行现场测试和问卷调查。研究发现,该小学夏季的室内温湿度偏高,满意度无法达到目标值的75%,热环境有待提升;建立热感觉投票与操作温度之间的关系模型,获得夏、秋、冬三季小学生热中性操作温度分别为25.76℃、26.16℃、21.39℃;夏热冬暖地区小学教室内75%的学生可接受操作温度范围为18.82~27.13℃,小学生的期望操作温度为21.19℃。根据室内热环境现有特征,提出相应改善建议,为今后夏热冬暖地区小学室内热环境优化提供参考。

In order to understand the characteristics of the indoor thermal environment of primary school classrooms in hot summer and warm winter areas,this paper selects a typical elementary school in Guangzhou,the representative city of this climate zone,as the research object,and conducts field tests and questionnaire surveys on the indoor thermal environment of the school’s classrooms.The study found that the indoor temperature and humidity of the elementary school in summer are relatively high,and the satisfaction cannot reach the target value of 75%.The thermal environment needs to be improved;the relationship model between thermal sensation voting and operating temperature is established,and the primary school students′heat in summer,autumn and winter are obtained.The operating temperature is 25.76℃,26.16℃,21.39℃ respectively;75% students in elementary school classrooms in hot summer and warm winter area can accept the operating temperature range of 18.82~27.13℃,and the expected operating temperature of primary school students is 21.19℃.According to the existing characteristics of the indoor thermal environment,corresponding improvement suggestions are proposed to provide reference for the optimization of the primary school indoor thermal environment in the hot summer and warm winter areas.
