Abstract

A natural lighting ventilation noise-reduction window capable of at least reducing 15dB within the noise range of 125Hz to 8000Hz belongs to the technical field of building doors and windows. In order to solving the noise problem in ventilation and lighting, the ventilation effect and the noise reduction effect are enabled to be best compromised. Indoor ventilation ports and outdoor ventilation ports are alternately arranged, and the area of each indoor ventilation port is identical to that of each outdoor ventilation port; the width of each indoor ventilation port and the width of each outdoor ventilation port are respectively W-2*(30 to 40)mm, the height RSO of each indoor ventilation port and the height SSO of each outdoor ventilation port are respectively (0.2 to 0.3)*H, a distance TWW between two window frames is 40 to 290mm, and a central line which is vertical to the indoor ventilation ports is arranged right above or right below and parallel to a central line which is vertical to the outdoor ventilation ports; a distance TSL between the indoor ventilation ports and the outdoor ventilation ports is 0.4H to 0.6H; wherein the W indicates the width of the window and is less than or equal to 2000mm; and the H indicates the height of a window (1) and is less than or equal to 2000mm. Due to the adoption of the window, the noise can be effectively lowered in lighting and ventilation.

Description

technical field [0001] The invention relates to a window for natural lighting, ventilation and noise reduction, which belongs to the technical field of building doors and windows. Background technique [0002] Designing green building envelopes is often associated with acoustic issues. For example, windows with double or multiple glazing are beneficial for energy saving and noise reduction. From another point of view, encouraging the use of natural ventilation is one of the important topics of green buildings, but opening windows often causes noise problems. Although some noise-reducing windows are provided in the prior art, for example, the invention application whose publication date is August 4, 2010 and whose publication number is CN101793122A provides a kind of noise-reducing window that can naturally ventilate and adjust natural lighting, but does not provide The specific noise reduction techniques, various parameters that affect noise reduction, and the relationship...
