A streamlined ventilation and noise reduction window

Abstract

The invention relates to a streamline ventilating and silencing window. The streamline ventilating and silencing window consists of an upper side window body (1) and a lower side window body (2), wherein the upper side window body (1) is of a dual-layer hollow inwards-convex structure, the lower side window body (2) is of a single-layer casement structure, an air inlet outer window (3) which can be opened and closed is arranged on the upper side window body (1) and is used as a ventilating duct inlet, a silencing unit (4) is arranged in the upper side window body (1), a vertical air outlet (5) is formed in the connecting surface of the upper side window body (1) and the lower side window body (2) and is used as a ventilating duct outlet, air enters the upper side window body (1) through the air inlet outer window (3), and after being silenced by the silencing unit (4), the air enters indoors from the vertical air outlet (5). Compared with the prior art, the streamline ventilating and silencing window has the advantages that not only can the inlet and outlet resistance of air flow be reduced, but also the noise reduction spectrum of the ventilating and silencing window is widened and the noise reduction amount is improved.

Description

technical field [0001] The invention relates to the field of building exterior noise control and treatment, and in particular relates to a streamlined ventilation and noise reduction window, which is suitable for ventilation, lighting and sound insulation of buildings on both sides of the road. Background technique [0002] In recent years, with the rapid development of urban traffic, the resulting traffic noise pollution has become increasingly serious. At the same time, good indoor ventilation is a necessary requirement for daily life. For this reason, ventilation and anechoic window technology has become an indoor noise reduction measure commonly used in buildings in noise-polluted areas. Generally, ventilation and anechoic windows can be divided into two types according to their ventilation characteristics: mechanical ventilation and natural ventilation. For example, the mechanically ventilated and sound-proof window with double-layer hollow glass with the patent numbe...

Problems solved by technology

The technology of relying on natural ventilation for ventilation is basically to let the air flow pass through the noise-absorbing channel with specially designed sound-absorbing material or sound-absorbing structure inside, so that the outdoor noise is greatly attenuated when passing through the noise-absorbing channel, but at this time the noise is eliminated. Channels generally have a large resistance coefficient (pressure loss) to airflow
