针对工位送风空调形式营造的非均匀热环境,利用等效温度指标对人体的局部和整体热感觉进行了评价。在准办公室环境对受试者进行了人体热反应实验,得到了不同刺激工况下人体各部位的热感觉和等效温度值,对比分析后发现:刺激部位等效温度值与非刺激部位等效温度值出现明显的分离现象;刺激温度和风速是影响刺激部位等效温度值的重要因素。由热感觉投票值与等效温度值的散点图发现,二者有很好的线性关系,通过拟合得到了适用于工位送风非均匀环境的等效温度舒适区范围。
Aiming at the non-uniform thermal environment created by the form of air supply and air conditioning in work station, the local and global thermal sensation of human body was evaluated by using equivalent temperature index. In the quasi-office environment, the subjects were subjected to human thermal response experiments, and the thermal sensations and equivalent temperature values of various parts of the human body under different stimulation conditions were obtained. After comparison and analysis, it was found that the equivalent temperature values of the stimulation sites and non-stimulation sites Effective temperature values appear obvious separation phenomenon; stimulation temperature and wind speed are the important factors that affect the equivalent temperature of stimulation site. From the scatter plot of the thermal sensation vote value and the equivalent temperature value, it is found that there is a good linear relationship between them, and the equivalent temperature comfort zone range suitable for the non-uniform air supply in the station is obtained through fitting.
