设计了一个数学模型来计算服装组合的各个层中的温度和干热传递，以及在他或她的区域的某一部分被辐射的人的总热损失。被外部热源照射的服装套装被认为是由内衣、滞留的空气和外层织物组成。使用热平衡方法对该模型进行了实验测试，使用受试者，改变两层套装外衣的活动、风和辐射特征。在两个实验中，受试者只能发出干热，因为他们被包裹在塑料箔中。该模型似乎是正确的约1摄氏度（均方根误差）和10 W m（-2）（均方根误差）。在第三个实验中，汗液蒸发也被考虑在内，表明所产生的生理热负荷的10%至30%的拦截额外的辐射是由额外的出汗补偿。由此产生的热应变相当温和。结果表明，该数学模型是研究辐射环境中双层系综传热的有效工具。
A mathematical model was designed to calculate the temperature and dry heat transfer in the various layers of a clothing ensemble, and the total heat loss of a human who is irradiated for a certain fraction of his or her area. The clothing ensemble that is irradiated by an external heat source is considered to be composed of underclothing, trapped air, and outer fabric. The model was experimentally tested with heat balance methods, using subjects, varying the activity, wind, and radiation characteristics of the outer garment of two-layer ensembles. In two experiments the subjects could only give off dry heat because they were wrapped in plastic foil. The model appeared to be correct within about 1 degrees C (rms error) and 10 W m(-2) (rms error). In a third experiment, sweat evaporation was also taken into account, showing that the resulting physiological heat load of 10 to 30% of the intercepted additional radiation is compensated by additional sweating. The resulting heat strain was rather mild. It is concluded that the mathematical model is a valid tool for the investigation of heat transfer through two-layer ensembles in radiant environments.
