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.
