Study on human heat dissipation in air conditioning coolingload calculation
摘要：
围绕空调设计规范中夏季人体散热量的计算方法,通过分析人与环境之间的换热过程,基于间接测热法实验和人体热平衡理论,建立了6～70岁不同年龄段人群在多种日常活动下的总散热量参照表,同时分析了人体散热量随年龄和性别的变化趋势,对相关规范中儿童和成年女性散热量分别为成年男性散热量75%和85%的折减系数进行了验证与修正,提出了针对儿童和青少年年龄增长特点的散热量折减系数计算方法。
Abstract：
Focusing on the calculation method of human heat dissipation in summer in the air conditioning design specifications, by analysing the heat transfer process between human and the environment, based on the indirect calorimetry experiment and the human heat balance theory, this paper establishes a reference table for total heat dissipation for people of different ages aged 6 to 70 under various daily activities. The change trend of human heat dissipation with age and gender is also analysed. The reduction coefficients in relevant specifications that states that the heat dissipation of children and adult women is 75% and 85% of that of adult men, respectively, are verified and corrected. A calculation method of the heat dissipation reduction coefficients based on the growth characteristics of children and adolescents is proposed.
