Active-passive thermal-insulation ventilation door/window unit

Abstract

Provides in the invention is an active-passive thermal-insulation ventilation door / window unit comprising a hollow glass panel, an aluminium alloy section bar, heat insulating strips, an electric blind, an air filtering net, an air conversion system, and an integrated control system. The unit is characterized in that the section bar of the window frame is divided into three parts; the heat insulating strips are arranged in the middles of the left part and the right part; the middle aluminium alloy section bar is provided with a ventilation system mounting cavity; and the electric blind is installed at the outermost side, approaching the outdoors, of the cavity. The air filtering net is installed at the inner side of the electric blind; the air conversion system is installed in the middle of the cavity; a decoration panel is installed at the outermost, approaching the indoors, of the cavity and the air filtering net is installed at the inner side of the panel. According to the invention, the CO2 concentration and temperature indoors can be detected automatically to determine whether ventilation and air exchange need to be carried out. On the condition of the ventilation and air exchange need to be carried out, the indoor and outdoor pressures are detected; when the indoor voltage is low, the electric blind is turned on and the air exchange is carried out by means of the natural power and the ventilation channel of the section bar; and when the indoor voltage is high, the electric blind and the fan motor are turned on, thereby realizing the air exchange by an active way.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to an active and passive heat-insulating 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...

[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
