Description

roof ventilator

technical field

The invention relates to building environment energy-saving technologies, in particular to a roof ventilator.

Background technique

Roof ventilators have been developed and applied as a sheltered natural ventilation technology for nearly 30 years. Since 2005, the products have been included in many national standards such as "Ventilation Skylight" (05J621-3) and "Selection and Installation of Roof Natural Ventilators" (06K105) Atlas has become the main natural ventilation selection design technology for domestic buildings. However, due to the limited technical conditions during the product development period and the lack of further product technology development in the later period, there is a lack of reliability technical guarantee in many major technical performances of roof ventilators.

The main technical application problems of the roof ventilator include the following aspects: 1. The rain and snow seepage problem on the top of the valve plate after it is closed; Dust causes the failure of the lighting function of the product. The main reason for the above technical application problems in various aspects is that the roof ventilator has been using backward valve plate structure and valve plate control technology.

Due to the above-mentioned large number of technical problems, it is difficult for roof ventilators to be applied to construction projects that require high rigor and safety. Since there are no alternative natural ventilation products for sheltered roofs, a large number of buildings cannot adopt energy-saving natural ventilation technology. Energy-consuming ventilation technologies such as fans and air conditioners have to be used, resulting in energy waste.
