大连养老建筑供暖季室内环境与老年人心率关联性

Correlation between indoor environment and heart rate of the elderly in Dalian elderly care buildings during heating season

为了解养老建筑室内环境与老年人心率之间的关联性,对大连城市和农村地区的26名住户在供暖季展开了调研及入户实测,对其室内环境参数及心率健康情况进行了72 h的连续监测,并采取问卷调查的方式获得受试老年人对室内环境的主观评价。研究结果表明:被调查的城市住宅室内热环境均表现良好,城市住宅的室内温度高于农村且温湿度的波动均小于农村;农村和城市的实测房间室内CO_(2)浓度均较高,农村室内的PM2.5污染严重,比城市室内平均浓度高出302%;实测房间无严重噪声污染,存在部分时间段噪声值超标情况,城市住宅的老年人对声环境营造有着更高的要求;老年人动态心率与温度、PM2.5浓度、噪声呈正相关关系。

In order to understand the correlation between the indoor environment of elderly care buildings and the heart rate of the elderly,this study conducts a survey and household measurement on 26 households in urban and rural areas of Dalian during the heating season.The indoor environmental parameters and heart rate health are continuously monitored for 72 hours,and a questionnaire survey is used to obtain the subjective evaluation of the indoor environment of the elderly tested.The research results show that the indoor thermal environment of the surveyed urban residences is well,the indoor temperature of the urban residences is higher than that of the rural residences,and the fluctuations of temperature and humidity are less than those of the rural residences.Both rural and urban measured rooms have higher CO 2 concentrations,and the PM2.5 pollution in rural rooms is serious,302%higher than the average concentration in urban rooms.There is no serious noise pollution in the measured rooms,the noise value exceeds the standard in some time periods,and the elderly in urban residences have higher requirements for the construction of an acoustic environment.The dynamic heart rate of the elderly is positively correlated with temperature,PM2.5 concentration and noise.
