作为风洞和现场测试的补充，乘客舱气候条件的模拟正变得越来越重要，以帮助提高热舒适性，同时减少车辆开发时间和成本。德尔福哈里森热系统公司与加州大学伯克利分校合作开发了预测乘员热舒适度的能力，以支持汽车气候控制系统。这种虚拟热舒适工程（VTCE）技术的核心是基于Stolwijk模型的人体热调节系统模型，但进行了一些改进。我们的模型使用了16个身体部分，每个部分都被建模为四个身体层（核心、肌肉、脂肪和皮肤组织）和一个衣服层。舒适性模型能够根据空气温度、周围表面温度、风速、湿度、太阳直射通量以及每个人的活动水平和服装类型，预测在高度不均匀的热环境中居住者的局部热舒适水平。VTCE考虑到乘客车厢的几何结构，包括玻璃表面，外壳的相关物理和热性能，特别强调玻璃性能。虚拟热舒适工程（VTCE）的使用将允许探索不同的气候控制策略，因为它们以快速和廉价的方式与人类热舒适有关。
Simulation of passenger compartment climatic conditions is becoming increasingly important as a complement to wind tunnel and field testing to help achieve improved thermal comfort while reducing vehicle development time and cost. Delphi Harrison Thermal Systems has collaborated with the University of California, Berkeley to develop the capability of predicting occupant thermal comfort to support automotive climate control systems. At the core of this Virtual Thermal Comfort Engineering (VTCE) technique is a model of the human thermal regulatory system based on Stolwijk’s model but with several enhancements. Our model uses 16 body segments and each segment is modeled as four body layers (core, muscle, fat, and skin tissues) and a clothing layer. The comfort model has the ability to predict local thermal comfort level of an occupant in a highly non-uniform thermal environment as a function of air temperature, surrounding surface temperatures, air velocity, humidity, direct solar flux, as well as the level of activity and clothing type of each individual. VTCE takes into account the geometrical configuration of the passenger compartment including glazing surfaces, pertinent physical and thermal properties of the enclosure with particular emphasis on glass properties. Use of Virtual Thermal Comfort Engineering (VTCE) will allow for exploration of different climate control strategies as they relate to human thermal comfort in a quick and inexpensive manner.
