热舒适性是评价座舱空调系统的重要指标.根据人体热平衡方程和Fanger 的舒适性假设建立了空调座舱的热舒适性计算模型,并给出了空调座舱热环境的评价方法,从而为热舒适的定量评价奠定了理论基础.应用此模型对3 种座舱空调方案的热舒适性进行了计算,从热舒适角度比较了3 种方案的优缺点,结果表明方案3 是最优方案 Thermal comfort is an important index to evaluate the cabin air conditioning system.According to the human body heat balance equation and the comfort hypothesis of the Fanger, the thermal comfort calculation model of the air-conditioned cabin is established and the evaluation method of the thermal environment of the air-conditioned cabin is given, Quantitative evaluation has laid the theoretical foundation.Using this model to calculate the thermal comfort of the three cockpit air conditioning programs, compared the advantages and disadvantages of the three programs from the thermal comfort point of view, the results show that the program is the best option 3
