高铁客站供暖空调系统设计、运行现状及研究展望

针对国内高铁客站供暖空调系统的设计、运行及研究情况进行了文献综述,重点关注了室内热湿环境状况、影响空调系统设计和运行的渗透风及室内末端方式等因素。从车站室内热湿环境状况来看,仍需结合高铁客站人员活动特点进一步研究适宜的热舒适需求参数;从渗透风影响情况来看,仍需对高铁客站的渗透风量与人员需求新风量之间的关系及调控方法等进行研究;从室内末端方式来看,喷口送风方式仍存在一定局限性,可借助辐射末端等改善高大空间的室内冬夏环境控制。

Design,operating status and research prospects of heating and air conditioning systems in high speed railway stations

Reviews the design, operation and research of heating and air conditioning systems in domestic high speed railway stations, focusing on indoor thermal environment, air infiltration and terminal devices. From the perspective of indoor thermal environment of the station, it is necessary to further study appropriate indoor thermal parameters in combination with the characteristics of passengers. From the perspective of air infiltration, it is necessary to study the relationship between infiltration air rate and outdoor air rate required by occupants and the control methods. From the perspective of terminal devices, there are some limitations of nozzle air supply method, and the radiant terminal is a novel approach recommended to improve the thermal environment in such kind of large space buildings.
