Underground stereo garage natural ventilation method

Abstract

The invention discloses an underground stereo garage natural ventilation method. The underground stereo garage natural ventilation method includes that a ground parking house is arranged above an underground stereo garage, a garage outer side ventilating duct and a garage bottom ventilating duct are respectively arranged the outer side of the periphery of the underground stereo garage and below the underground stereo garage, a ground parking house outer side ventilating duct communicated with the garage outer side ventilating duct is arranged on the outer side of the periphery of the ground parking house, a top natural ventilation port is formed in the top of the ground parking house, a plurality of inner side natural ventilation openings and a plurality of outer side natural ventilation openings are respectively formed in an outer wall and an inner wall of the ground garage outer side ventilating duct, and a plurality of underground parking space ventilation openings respectively corresponding to all underground parking units are formed in an inner wall of the garage outer side ventilating duct. The underground stereo garage natural ventilation method can achieve through type overall natural ventilation and air change for the underground stereo garage whether under parking and car fetching work status or under non-work status, effectively dilutes and excludes leaked oil gas odor and peculiar smells in the underground stereo garage, reduces device environment temperature in the underground stereo garage, and enhances smoke exclusion ability in a fire disaster.

Description

Technical field [0001] The invention relates to the field of ventilation of underground parking garages, in particular to a natural ventilation method for underground parking garages, and is particularly suitable for underground parking garages with a large buried depth and a large number of parking vehicles. Background technique [0002] With the development of society and economy, cars have gradually become popular in cities. According to statistics, there are more than 1 million cars in 31 cities across the country, of which more than 5 million cars in Beijing. Compared with scarce land resources in cities, parking spaces have become a hot favorite among car owners. For this reason, underground three-dimensional parking garages that can make full use of underground space have emerged. [0003] Traditional underground parking garage, such as figure 1 As shown, only through the opening and closing of the car's turntable when parking and picking up the car, the ventilation of the...

Problems solved by technology

[0003] The traditional underground three-dimensional parking garage, such as figure 1 As shown, the ventilation of the underground three-dimensional parking garage is realized only through the opening and closing of the car-carrying turntable when parking and picking up the car. Due to the oily smell released by the vehicle and the harmful gas accumulated at the bottom of the underground parking garage, the traditional ventilation method Failure to 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

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

In addition, the traditional underground three-dimensional parking garage does not consider the possibility of fire in the ground parking room, which also brings potential safety hazards
