摘　　要：研究了在模拟自然风的动态环境下人体热舒适评价模型,以室内温度、湍流强度、作用时间为变量,将其作为热舒适评价模型的指标集,以5级热感觉投票作为评价集,通过50名受试者的热舒适实验,得到了不同工况下的热舒适投票结果。利用模糊综合评价法,得到了权重集和评价矩阵,最后得到了不同指标集下的MTSV值。经过对比发现,实验结果中的人群不满意度与PMV-PPD指标差距较大,且随着温度越高差距越大。研究提出了适用于模拟自然风环境热舒适评价的MTSV-DP指标,结果表明:与传统的稳态空调环境相比,模拟自然风环境将室内舒适温度从26℃提高至28℃;新指标可以更为准确地反映人体在自然风环境的热舒适性,以人群不满意率小于15%为标准,MTSV的推荐值为-0.1~+0.1。The evaluation model of human thermal comfort in simulating natural wind environment were studied,with the indoor temperature,turbulence intensity and action time for variables,as the thermal comfort evaluation index of the model set,with five levels thermal sensation vote as evaluation set by 50 volunteers’ thermal comfort experiment,the thermal sensation vote of different conditions were obtained.The weight set and evaluation matrix were obtained by fuzzy comprehensive evaluation method,finally got the Mean Thermal Sensation Vote(MTSV) under different conditions.It is found that there is a large error between the population dissatisfaction rate calculated by PMV-PPD and the experimental results,and the error increases with the higher the temperature.The MTSV-DR index was proposed to evaluate the thermal comfort of simulating natural wind environment.The results showed that compared with the traditional steady-state air conditioning environment,the indoor comfort temperature was increased from 26 ℃ to 28 ℃.The MTSV-DR index can more accurately reflect the human thermal comfort of simulating natural wind environment,with the dissatisfaction rate less than 15% as the standard,and the recommended value of MTSV is-0.1~+0.1.
