1 室内空气环境定义 室内空气环境按其原有的定义应为:温度、湿度、流速和清洁度四种因素的综合,但在研究人体热舒适时,则将清洁度换成表面平均辐射温度,又称为热环境。人们对热环境已研究了大半个世纪,产生了很多标准,这些标准是空调设计的依据。但是,这些标准都是以稳态热环境为条件,以人体的主观热感觉处于中性、风速不大于0.15m/s、相对湿度50％等为最舒适的热环境。
1 Definition of indoor air environment According to its original definition of indoor air environment should be: temperature, humidity, flow rate and cleanliness of four factors, but in the study of human thermal comfort, the cleanliness will be replaced by the average surface temperature of radiation, Also called hot environment. People have been studying the thermal environment for more than half a century, has produced many standards, these standards are the basis of air conditioning design. However, these standards are based on the steady-state thermal conditions, the subjective thermal sensation in the human body is neutral, the wind speed is not greater than 0.15m / s, relative humidity 50% for the most comfortable thermal environment.
