Selection of Electric Window Opener
As the latest development of modern windows, an intelligent electric window opener is widely used in many fields
High-level window: the installation of the window is too high or far away, which cannot be reached by manpower alone
The window is too heavy, it is difficult to open or close, and the manual switch is inconvenient to use
Fire smoke exhaust windows with fire linkage ventilation requirements on floors
If there are weather requirements for opening/ closing windows, the windows should be closed automatically in case of rain in the warehouse
The room temperature requirements, such as vegetables or flowers greenhouse windows
If the temperature is too high, the window will be opened automatically, such as the window of the communication room
Strict requirements for indoor air index, timely ventilation
Indoor needs more appropriate brightness, need to adjust the shutter angle to achieve
Windows need more strict sealing fore, such as skylight rainproof need to be closed more tightly
Other special occasions, such as chemical, dust, and other factory workshops, need timely ventilation
Green, intelligent, energy-saving two generations of high-rise buildings, such as curtain walls and windows
Characteristics of window opener
It can automatically open or close single or multiple windows by means of remote control (the distance between the remote control and indoor can be more than 50 meters), manual button, centralized control of computer host, or remote control of mobile phone (telephone), which brings great convenience to users' life. It improves people's quality of life.
It can be linked with the alarm center of the public security fire department to realize the fire safety control of smoke exhaust windows.
Through the expansion and assembly of body sensors, wind and rain sensors, smoke alarms and temperature controllers, timers, and other intelligent devices, the anti-theft is realized.
Selection of window opener
> > > Selection of window opener
Power supply for window opener: AC220 V, ac110 V, DC24 V and other common daily ventilation power supply AC220 V must be used
when there are fire requirements
> > > Selection of push and pull force for window opener
Generally, between 200n-1200n, simple thrust calculation F-1 / 2 (self-weight of window sash) * (maximum opening stroke/window height), the force of the smallest window opener is 200N, which can basically meet the use of general windows.
> > > Select the travel or angle of the window opener
Opening stroke: the required opening angle is converted into the straight-line distance of the window opening (according to the cosine theorem), and the daily ventilation opening angle is generally not more than 30。 and the stroke is 300-400mm; however, for fire protection requirements, the opening angle of the window is generally 50° when the fire signal linkage and the specific design requirements shall prevail.
> > > Choose the type of window opener
1. Push pull force of chain window opener: 200N, 400N, 600n-800n stroke: 200, 300, 400-1200mm
2. Screw type window opener push pull force: 200n-1000n, 1500N, 2000N, stroke: 50, 300, 400-1500mm
The chain-type electric window opener is suitable for closing the window in a straight line, and the window sash has good sealing.
Up/ down / hanging window; chain type, screw type can also be used, but the screw type has the largest thrust, and the chain type is more beautiful.
3. The designed window is wide or overweight: the window is large (more than 1.5m wide) or needs a large push / pull force (more than 450N) when opening / closing the window. It will be considered to use a double electric window opener. There are double screw types and double chain types, that is, two screw-type window openers or two chain-type window openers.
4. Electric push-pull window opener: customized according to the width of the window, synchronous belt drive.
5. Electric sliding skylight: the single opening area of an electric sliding window can be 5m, and it can be opened in a large area when combined. Unique structural design, waterproof and rainproof design, in order to achieve better waterproof requirements, the window adopts advanced four corner welding technology.
