Abstract

In winter, the elevator shaft of super high-rise buildings causes a significant chimney effect. The elevator door cannot be closed normally, which severely affects the regular operation of the building. In this study, the computational fluid dynamics method was used to simulate outdoor air conditioning, analyze the effects of an opening area of 1 m² and different opening distances on the elevator shaft, and simulate the cooling effect of air mechanically fed at volume rates of 3600–10800 m³/h. The results showed that the combined natural and mechanical ventilation transmitted cold outdoor air with the most significant effect. The relationship between the theoretical thermal pressure and the pressure difference between the two sides of the elevator door was established and combined with actual measurements of the pressure difference between both door sides at different outdoor temperatures. The effects of different measures on the pressure difference between the two sides of the elevator door were analyzed.
