摘要
目的研究太阳辐射对于人体热舒适性的影响.方法在沈阳建筑大学蓄能电热地板实验室内,对在校学生进行人体舒适性研究,维持室内的热湿环境不变,采用问卷调查方式分别统计在有、无太阳辐射的室外条件下对于热感觉、空气湿度感及吹风感的评价.结果有太阳辐射时中性温度为22.24℃,无太阳辐射时中性温度为23.05℃,期望温度略高于中性温度,两者基本吻合;有太阳辐射时线形回归的斜率为0.37℃,无太阳辐射时线性回归的斜率为0.36℃;有太阳辐射时最低不满意率LPPDs=4%,而无太阳辐射时最低不满意率LPPDs=5%.结论与无太阳辐射的情况相比,在有太阳辐射时受试者的中性温度和期望温度较低一些,人体对于温度的变化的敏感程度稍大,且人体对环境更容易满足.
Objective The research of the impact of solar radiation on human thermal comfort was conducted.Method In the energy-storing floor heating room of Shenyang Jianzhu University,an experiment for human thermal comfort of the students on campus was launched.Different surveys were made to record the evaluation of the thermal sensation,air humidity and the draft reaction with solar radiation and without solar radiation,with maintaining the indoor environment.With solar radiation,the neutral temperature was 22.24℃ and increased to 23.05℃ without it;besides,their expectation temperatures in different conditions were similar,and both higher than their neutral temperatures.With solar radiation,the rate of curve fitting was 0.37℃ and decreased slightly to 0.36℃ without it.Meanwhile,LPPDs were different with and without solar radiation,which were 4% and 5% respectively.Compared with the results in the condition without solar radiation,influenced by the solar radiation the neutral temperature and the expectation temperature of respondents were a little lower,and respondents appeared more sensitive to the change of the temperature and were easily satisfied with the indoor environment.
