建筑室内热环境的模糊评判模型

Fuzzy Evaluation Model on Indoor Thermal Environment Inside a Building

以地板送风空调房间为对象 ,通过大量调查与人体热舒适实验 ,引入模糊数学的方法 ,确定了 4个室内环境主要影响因素 (环境温度、风速、相对湿度、平均辐射温度 )相对于热感 7级别的隶属函数 ,并建立了相应的热舒适模糊综合评判模型 .

Man's thermal sense itself is a very vague concept and its boundaries of each level can not be determined explicitly. In the light of the four factors affecting the thermal comfort(indoor air temperature, air velocity, relative humidity, mean radiation temperature), a series of experiments on body thermal comfort were carried out based on an underfloor air conditioning room. The subordinate functions of the four factors related to each thermal sensation grade were determined through fuzzy statistics. And a fuzzy synthetical evaluation model on indoor thermal environment was established, which lays the foundation for the accurate reflection of the thermal sensation of people in the room.
