Active-passive type ventilation door and window

Abstract

The invention provides an active-passive type ventilation door and window, which comprises a hollow glass panel, an aluminum sectional material, an electric shutter, air filter screens, an air conversion system and an integrated control system. The active-passive type ventilation door and window is characterized in that the window frame sectional material is divided into three parts; the left part and the right part are connected with the glass panel; the middle part is provided with a ventilation system installing cavity; the outermost side, near the outdoor position, of the cavity is provided with the electric shutter; the inner side of the electric shutter is provided with the air filter screen; the middle part of the cavity is provided with the air conversion system; the outermost side, near the indoor position, of the cavity is provided with a decoration panel; and the inner side of the panel is provided with the air filter screen. The active-passive type ventilation door and window can be used for automatically detecting the indoor CO<2> concentration and the indoor temperature, and can judge whether the ventilation is needed or not; under the condition that the ventilation is needed, the indoor and outdoor air pressure is detected, when the indoor air pressure is low, the electric shutter is opened, and the natural power and ventilation passages of the sectional material are used for realizing the ventilation; and when the indoor air pressure is high, the electric shutter is opened, meanwhile, a fan motor is started, and an active mode is adopted for realizing the ventilation. An active-passive combined type ventilation mode is adopted.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to an active and passive ventilation door and window. Background technique [0002] Based on the consideration of safety and external environment, when the traditional doors and windows are closed, they cannot meet the needs of indoor ventilation and ventilation, and ventilation devices are needed for ventilation. According to the way of ventilation, the current auxiliary ventilation devices for doors and windows are mainly divided into two categories: 1. A special ventilator is used for ventilation, which needs to be installed around the window material, which affects the appearance and consumes a lot of energy; 2. 1. Open vents on the inside and outside of the profile to form a ventilation channel with the profile cavity, and use the difference in indoor and outdoor air pressure to achieve natural ventilation. However, when the outdoor air pressure is lower than t...

[0002] Based on the consideration of safety and external environment, when the traditional doors and windows are closed, they cannot meet the needs of indoor ventilation and ventilation, and ventilation devices are needed for ventilation.

According to the way of ventilation, the current auxiliary ventilation devices for doors and windows are mainly divided into two categories: 1. A special ventilator is used for ventilation, which needs to be installed around the window material, which affects the appearance and consumes a lot of energy; 2. , Open vents on the inside and outside of the profile, and form a ventilation channel with the profile cavity, and use the difference in indoor and outdoor air pressure to achieve natural ventilation, but when the outdoor air pressure is lower than the indoor air pressure, it is difficult to achieve ventilation
