Abstract

Thermal comfort evaluation for vehicle occupants is very complicated due to the transient nature and non-uniformity of the vehicle interior. The thermal sensation of an automobile occupant is affected by the surrounding environment. Furthermore, the existing standard was developed for steady state and controlled conditions and it utilizes three evaluation indices, some of which are not adapted for this complex environment. In this article, the three standardized indices are compared in terms of thermal comfort, for a passenger vehicle in summer season. The results show that the mean values of the PMV/PPD model calculated at a single point with Comfort Sense equipment are far from the TSV mean values which were collected in questionnaires, while the t_eq index which was calculated with an advanced thermal manikin are closer to the TSV comfort votes. This may be explained by the fact that the TSV and t_eq consider the sensation for each body part at the local level. For a correct evaluation of the thermal comfort in non-uniform and transient environments like in vehicles, it is not enough to measure a single point.

摘要

由于车辆内部的瞬态性质和不均匀性，对车辆乘员的热舒适性评估非常复杂。汽车乘客的热感会受到周围环境的影响。此外，现有标准针对稳态和受控条件而开发，它利用了三个评估指标，其中一些不适用于这种复杂的环境。在本文中，比较了夏季乘用车在热舒适性方面的三个标准化指标。结果表明，使用Comfort Sense设备在单个点上计算的PMV / PPD模型的平均值与问卷中收集的TSV平均值相差甚远，而t _eq 用高级人体模型计算出的指数更接近TSV舒适度投票。这可以通过一个事实，即TSV和解释牛逼_EQ 考虑在地方一级的每个身体部位的感觉。为了正确评估不均匀和瞬态环境（如车辆）中的热舒适性，仅测量一个点是不够的。
