Potential analysis of natural ventilation in the New Guangzhou Railway Station

Optimizes the natural ventilation design of the station using multi-zone network simulation toolkit ContamW. The optimization results reveal that when the outdoor temperature is lower than 21 ℃, indoor air exchange rate and thermal comfort can be satisfied simply by natural ventilation, while when the outdoor temperature ranges from 21 ℃ to 28 ℃, natural ventilation should be used by preference and the air conditioning system be used as an auxiliary to natural ventilation zones, the air conditioning systems of other zones run to lower the temperature, and when the outdoor temperature is higher than 28 ℃, all air conditioning system run and the doors and windows of the building should be kept closed.
