【摘要】 利用MATLAB/SIMULINK平台,建立了空调硬座列车的围护结构动态传热及PMV的计算模型;其中在PMV的计算中,考虑了人体散湿量、空气相对湿度及内壁温度和平均辐射温度对PMV-PPD值的影响。对空调硬座列车空调双位控制分别采用不同的反馈信号对热舒适性的影响,进行了理论上的分析。本文建立的模型,可用于列车空调相关问题的研究。 【Abstract】 The model to calculate the PMV-PPD and dynamic heat transfer of air-conditioning passenger train envelops enclosure was built based on MATLAB/SIMULINK.Then the model was used to theoretically analyze the result of PMV under the strategy of two position control which separately adopted the feedback signal of carriage's temperature and the PMV-PPD.And in the calculation of PMV-PPD,the impact of correlative parameters were considered,which including the moisture gain from occupants,air relative humidity,temperature of inner wall face and the mean radiant temperature etc.The model can be used in the research on related problems. 【关键词】 列车空调; 状态空间法; PMV; 双位控制 【Key words】 air conditioner of passenger train; state space; PMV; two position control
