Underground stereo parking garage and natural ventilation method thereof

Abstract

The invention discloses an underground stereo parking garage and a natural ventilation method thereof. The garage comprises the underground stereo parking garage, a ground parking room and an underground stereo parking garage mechanical ventilation device, wherein the ground parking room is arranged above the underground stereo parking garage; a vehicle inlet and a vehicle outlet are formed in the ground parking room; the underground stereo parking garage mechanical ventilation device comprises externally hung exhaust well channels arranged on the two sides of the integral body of the underground stereo parking garage and the ground parking room, and exhaust fans arranged inside the externally hung exhaust well channels; a garage bottom air flue communicated with the externally hung exhaust well channels on the two sides is arranged at the bottom of the underground stereo parking garage; a ground air outlet is formed in the position, relative to the ground parking room, of each of the externally hung exhaust well channels. According to the underground stereo parking garage and the natural ventilation method thereof, the peculiar smell of the underground stereo parking garage can be effectively and quickly diluted and removed no matter in the vehicle taking-out and placing-in condition and the condition that users wait for taking out and placing in the vehicles, and the environment temperature of equipment such as a transformer inside the underground stereo parking garage is remarkably decreased.

Description

technical field [0001] The invention relates to underground garage ventilation, in particular to an underground three-dimensional parking garage and a natural ventilation method thereof, and is especially suitable for a large-volume, deep-buried underground three-dimensional parking garage. Background technique [0002] With the development of society and economy, cars are gradually popularized in cities. According to statistics, there are 31 cities across the country with more than 1 million cars, including more than 5 million cars in Beijing. Compared with the scarce land resources in cities, parking spaces have become a hot favorite among car owners. Because of this, the underground three-dimensional parking garage that can make full use of the underground space came into being. [0003] The traditional underground three-dimensional parking garage (such as figure 1 As shown) only through the opening and closing of the car-carrying turntable when parking and picking up ...

AI Technical Summary

Problems solved by technology

[0003] The traditional underground three-dimensional parking garage (such as figure 1 As shown) only through the opening and closing of the car-carrying turntable when parking and picking up the car, the ventilation of the underground three-dimensional parking garage is realized. Due to the oily smell released by the vehicle and the harmful gas accumulated at the bottom of the underground garage, the traditional ventilation method cannot meet hygiene requirements

When inspection and maintenance personnel enter the parking garage, they can only carry the oxygen supply equipment on their backs, which not only increases the baggage, but also makes it inconvenient for inspection and maintenance

[0004] In addition, poor ventilation will lead to heat accumulation in the underground three-dimensional parking garage, reducing the efficiency of electrical equipment such as transformers and control cabinets. In the long run, it will affect the service life of equipment
