Lighting ventilation device of assembled underground garage and calculation method thereof

Abstract

The invention belongs to the field of green buildings, relates to a lighting ventilation device of an assembled underground garage and a calculation method thereof. The device integrates components such as a lighting ventilation shaft, a well wall, a specular reflection or diffuse reflection coating, a water intercepting ditch, a ground fixing frame, a water baffle, a transparent ventilation louver, a top lighting cover, a solar power generation energy storage lamp, a waterproof layer, and a protection railing, and realizes natural lighting and natural ventilation of the underground garage andindoor and outdoor night illumination. The size and structure of the lighting ventilation shaft can be optimized through scientific calculation for a better lighting ventilation effect.

Description

technical field [0001] The invention belongs to the field of green buildings, and relates to a lighting and ventilation device for an assembled underground garage and a calculation method thereof. Background technique [0002] At present, measures to improve natural lighting in underground spaces mainly include daylighting skylights, sunken courtyards, light pipes, daylighting atriums, patios, reflectors, etc. Some of these technologies can only achieve a single natural lighting or natural ventilation function, and some are affected by Due to the limited space on site or water leakage due to poor workmanship on site, these lighting or ventilation technologies have not been promoted on a large scale. [0003] However, in the prior art, there is no relatively standardized design process for the design parameters of the lighting and ventilation shaft, and it is impossible to maximize the lighting and ventilation performance of the lighting and ventilation shaft, improve the con...

Problems solved by technology

[0002] At present, measures to improve natural lighting in underground spaces mainly include daylighting skylights, sunken courtyards, light pipes, daylighting atriums, patios, reflectors, etc. Some of these technologies can only achieve a single natural lighting or natural ventilation function, and some are affected by Due to the limited space on site or the occurrence of water leakage due to poor workmanship on site, these lighting or ventilation technologies have not been promoted on a large scale

[0003] However, in the prior art, there is no relatively standardized design process for the design parameters of the lighting and ventilation shaft, and it is impossible to maximize the lighting and ventilation performance of the lighting and ventilation shaft, improve the controllability of its natural ventilation capacity, and improve the daylighting coefficient of the overall lighting and ventilation device
