“…A survey by Yin et al found that the fresh air load at the station was as high as 34%-37% [23]. It should be noted that the PSD has air leakage problem, because it is not completely sealed [24]. The PBD does not completely separate the station from the tunnel.…”

The piston effect and piston wind generated by subway train operation are closely related to the energy consumption of subway environmental control system. With the rapid development of subway industry, under the premise of meeting the needs of passengers, using piston wind to reduce station energy consumption has become one of the focuses of current research. This paper collects and sorts out the domestic and foreign literature related to the piston effect. Firstly, the relevant information of piston effect and subway environmental control system is summarized and analyzed. Secondly, the utilization strategy of piston wind is emphasized in this paper. These strategies are mainly related to the design of ventilation shaft, the speed of train, the selection of platform door and the installation of door curtain. Reasonable use of these strategies can reduce energy consumption for the station. Finally, the utilization principle of piston wind was proposed in this review. When the piston wind meets the demand, the piston ventilation should be a priority choice, compared with mechanical ventilation. Evaluating whether the piston wind meets the needs of use, mainly through these parameters as the judgment basis, such as air volume, temperature and humidity, carbon dioxide concentration and particle concentration.
