By this study, it was aimed to define a testing and calculation model for thermal comfort assessment of a bus HVAC design and to compare effects of changing parameters on passenger's thermal comfort. For this purpose, a combined theoretical and experimental work during heating period inside a coach was carried out. The bus was left under 20 °C for more than 7 h within a climatic chamber and all heat sources were started at the beginning of a standard test. To investigate effects of fast transient conditions on passengers' physiology and thermal comfort, temperatures, air humidity and air velocities were measured. Human body was considered as one complete piece composed of core and skin compartments and the Transient Energy Balance Model developed by Gagge et al. in 1971 was used to calculate changes in thermal parameters between passenger bodies and bus interior environment. Depending on the given initial and environmental conditions, the graphs of passengers Thermal Sensation and Thermal Discomfort Level were found. At the end, a general mathematical model supported with a related experimental procedure was developed for the use of automotive HVAC engineers and scientists working on thermal comfort as a human dimension.
通过本研究，旨在定义一种用于客车暖通空调（HVAC）设计热舒适性评估的测试和计算模型，并比较参数变化对乘客热舒适性的影响。为此，在一辆长途客车内部的供暖期开展了理论与实验相结合的工作。该客车在气候试验箱内保持在20℃以下超过7小时，在标准测试开始时启动所有热源。为了研究快速瞬态条件对乘客生理和热舒适性的影响，测量了温度、空气湿度和风速。人体被视为由核心和皮肤部分组成的一个完整整体，并使用Gagge等人在1971年开发的瞬态能量平衡模型来计算乘客身体与客车内部环境之间热参数的变化。根据给定的初始条件和环境条件，得出了乘客热感觉和热不舒适水平的图表。最后，开发了一个由相关实验程序支持的通用数学模型，供从事热舒适性这一人为因素研究的汽车HVAC工程师和科学家使用。
