Description

Technical Field

[0002] With the accelerating urbanization process today, underground parking lots, as an indispensable infrastructure in modern cities, have seen a rapid expansion in scale and quantity. The increase in underground parking lots has greatly alleviated the pressure on ground parking spaces and provided strong support for the smooth operation of urban traffic. However, while enjoying the convenience it brings, the air circulation problem in underground parking lots has sparked extensive discussions. The enclosed structural characteristics of underground parking lots make it difficult for natural wind to directly penetrate, resulting in a slow air circulation and renewal speed. While pursuing the efficient use of land resources, how to ensure the air circulation inside underground parking lots has become an important problem that urgently needs to be solved.

[0003] In large underground parking lots, due to differences in functional layout and spatial location in each area, different air flow demand characteristics are presented. Specifically, in the entrance and exit areas where vehicles frequently enter and exit, as the key hub for internal and external air exchange, the air circulation is efficient and fast, and the air quality is relatively good; while those areas hidden in deep corners or far from the main passage often become blind spots for air circulation, prone to air stagnation, resulting in a decline in local air quality, invisibly threatening the health and safety of people in the parking lot and the overall comfort experience. Currently, most underground parking lots still use traditional ventilation equipment, which is limited by fixed wind direction settings and limited ventilation coverage, resulting in the inability to comprehensively cover the air circulation of the entire underground parking lot.

[0004] Therefore, how to design an underground parking lot ventilation device that can achieve flexible ventilation, as an auxiliary to traditional ventilation equipment, to help comprehensively cover and optimize the air circulation of the entire underground parking lot is a technical problem that has not been solved in the prior art.
