基于等效温度的工位空调环境下热舒适区研究
Thermal comfort zone study based on equivalent temperature under task air conditioning system
摘要：
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。
Abstract：
Evaluates the local and overall thermal sensation using equivalent temperature index in the non-uniform thermal environment of task air conditioning system. Conducts the human thermal test in a mockup office, and obtains the data of local sensation and equivalent temperatures under different stimulating conditions. The results show that there is an obvious separation phenomenon between the equivalent temperature of stimulating site and that of non stimulating sites. The air temperature and velocity are the important factors to affect the equivalent temperature of the stimulating site. From the scatter plot, finds a good linear relationship between human thermal sensation vote and equivalent temperature. Obtains the equivalent temperature comfort zone for the non-uniform thermal environment with task air conditioning through the fitting method.
