Analysis And Research On The Space Environment Of Kindergarten Activity Room In Guangzhou City Based On The Correlation Between Usage Behavior And Thermal Comfort

As the birth population increases year by year,the preschool gross enrollment rate also increases.The activity room in kindergarten is a space used by children for a long time,and its use and physical environment are closely related to the health of children.Therefore,by understanding and discussing the use environment of a mature kindergarten,finding the factors that are not conducive to the healthy growth of young children,can play a role in urging its improvement and suggesting its optimization.Also,the design of kindergartens in the future can also draw lessons from existing practical cases,obtain inspiration and inspiration,and create a more comfortable and healthy growth environment for young children.This research analyzes and summarizes the spatial characteristics and usage status of the two kindergartens through the field survey on the usage status of activity rooms with different natural ventilation conditions.And through the on-site testing of the physical environment,the physical environment status and change characteristics of the two natural ventilation condition activity rooms are obtained.Based on the measured data,verify the simulation software and use it to simulate the indoor thermal environment comfort of the two natural ventilation conditions under different use densities and working conditions,and explore the use of density and working conditions for the indoor heat The impact of environmental comfort.It aims to provide refined guidance for the use of kindergarten activity rooms with different ventilation conditions,provide references for the refined design of kindergartens in the future,and provide new ideas for energy conservation research in kindergartens in Guangzhou.Based on the above,this study is mainly divided into the following parts:First,through field investigations on the usage status of activity rooms with different natural ventilation conditions in the two kindergartens,their respective spatial characteristics and usage status were analyzed and summarized.(Chapter Two)Secondly,Through the on-site test of the physical environment,the data of the indoor physical environment indicators are obtained,and the data are sorted and summarized to obtain the physical environment conditions and change characteristics of the two natural ventilation conditions.Then,based on the data obtained from the actual measurement,the indoor thermal environment simulation software is verified.(Chapter Three)Thirdly,the simulation software was used to simulate the indoor thermal environment comfort time of two common natural ventilated activity rooms that accommodate children of different ages and different use densities,and found that the use density has a certain effect on the indoor thermal comfort of the activity room: The lower the use density,the higher the indoor thermal environment comfort and the longer the comfort time.And overall,the comfort of the double-sided naturally ventilated activity room is higher than that of the single-sided naturally ventilated activity room.When designing the kindergarten activity room,from the perspective of the indoor thermal environment comfort,comprehensively considering the use of all ages,the design reference value of the number of people in each class of the kindergarten: the recommended number of kids of double-sided natural ventilation activity rooms is 26,30 or 35.The recommended number of kids of single-sided natural ventilation activity rooms is 27?30.(Chapter Four)Finally,the simulation software was used to simulate the indoor thermal environment of children in two natural ventilation conditions under different working conditions.The study summarized the influence of various working conditions on the indoor thermal environment comfort,and proposed the low-range operation of the electric fan and air conditioning control.It is recommended to use the working condition of 29?30?.(Chapter Five)This study classifies the kindergarten activity room with the ventilation condition as the standard,which fills the gap in the study of indoor thermal comfort in kindergartens in Guangzhou.And the study uses building performance simulation software to study the impact of use density and working conditions on the indoor thermal environment comfort time,provides a new workflow for evaluating the indoor thermal environment of kindergartens.At the same time,this article quantitatively studies the comfort of double-sided natural ventilation and single-sided natural ventilation activity rooms under different use densities and working conditions,and puts forward relevant suggestions.
