Thin roof ventilator

Abstract

Disclosed is a trussed, natural lighting and ventilating skylight, comprising multiple rows of parallel structural trusses (1), an outer protective panel (3) provided all around the multiple rows of structural trusses (1), multiple ventilation units (102) provided for each row of structural trusses (1), an intermediate layer of V-shaped weatherboard (5) connected between each line of positionally opposing ventilation units (102), a partition panel (13), an upper layer of V-shaped weatherboard (9) and a V-shaped water collecting sump (12) respectively provided between two adjacent lines of ventilation units (102), and a wind-shielding valve plate (6) respectively hinged on two adjacent rows of structural trusses (1). The ventilating skylight can save on material, is easily standardized, has an automatic wind shielding and regulating function against the force of the wind, and can ventilate and provide natural lighting to a large area of a building. The wind-shielding valve plate can be instantly and automatically opened, thereby ensuring a fast and large amount of ventilation and fume extraction.

Description

technical field [0001] The invention relates to a building energy-saving ventilation device, in particular to a thin roof ventilator. Background technique [0002] The demand for building energy-saving applications has stimulated the development and application of building natural ventilation technology products. In recent years, thin roof ventilators have gradually been selected by certain designs and users. A kind of roof ultra-thin streamline ventilator disclosed by CN201589368U and a kind of assembled light roof ventilator etc. disclosed by CN202501595U. [0003] However, the development of conversion technology has gradually become erroneous, and the original simple and economical natural ventilation product technology tends to be complicated: 1. The board molded special-shaped material technology used is not conducive to product standardization, popularization and popularization, and is not conducive to product material selection It is interchangeable with applicat...

AI Technical Summary

Problems solved by technology

According to the ventilation flow formula Q= mu f m 3 / s, for a ventilation device of a certain specification, the increase of the overlapping degree will reduce the effective flow area F inside the ventilator, and the too low (thin) wind shelter structure will increase the ventilation resistance after increasing the exhaust air circumvention, and the flow coefficient mu Reduced, these methods of strengthening wind shelter all reduce the ventilation flow Q, that is, the ventilation performance of the product decreases

[0005] In order to enhance the wind-shielding performance, CN202501595U discloses an assembled light roof ventilator with a translational valve plate device, but since the valve plate device is located at the air inlet at the bottom of the ventilator , when the valve plate is closed, the ventilator will lose its ventilation ability, and external pollutants are more likely to fall on the valve plate with the wind, and the falling snowflakes will melt and drip into the building, causing pollution in the building
