In the era of rapid growth, electric window openers can make our lives more convenient and efficient, but there are many types of electric window openers, each with a wide range of functions and applications. I would like to briefly introduce to you how to choose an electric window opener correctly and reasonably?
1. Choose the type of electric window opener
Electric window openers are systems that automatically open and close various windows inside and outside buildings by driving them with electrical equipment, and are divided into chain type window openers and spiral type window openers according to mechanical driving methods. Choose an electric window opener based on the designed window type. To determine the type of window, there are upper suspension, lower suspension, middle suspension, sunroof, pull window, casement window, inclined window, exhaust window, and other special windows and devices.
1. For skylights: Firstly, choose a push type electric window desk, which is mainly suitable for withstanding vertical forces, has no possibility of bending, and has strong resistance to wind and rain. The thrust is usually very high.
2. For sliding windows: When choosing a direct dial electric window sill, this method is suitable for straight line operation, and the sealing degree of the window sash when closing the window is also good.
3. For blinds: You can choose a small paddle type electric window sill.
4. In the case of top/bottom/suspended windows: If it is a chain type, it may be a cushion type, but the pushing and pulling force of the cushion type is greater.
If the window is large, it will be overloaded: the width of the window is large (over 1.5 meters wide), and the required thrust/tension to open it is large (over 450 n), which is the electric opening of the dual air conditioner. Considering that a unit comes to the same window at the same time and has two chain sliding doors to ensure stability when opening the window and sealing when closing.
2. Choose the stroke and angle of the electric window opener (which may slightly affect the price range)
Opening stroke: Convert the required opening angle to a sine value, which is half of the straight-line distance (stroke) of the window opening=2 * window height * opening angle. Based solely on daily ventilation, the opening angle should not exceed 30 degrees, but the travel should be 300-400 millimeters. If required by the fire department, always maintain a temperature of 70 degrees when linking fire signals.
3. The choice of thrust for electric window openers (which has a significant impact on the price range)
Between the typical 200N-600N commercial chain, between the typical 200N-1000N push rod, and between 1000N-2000N are Toomohiro's patch door flashers. Tomohiro's motor has a diameter>1000N ≤ 1000N, which is slightly larger. A simple push-pull calculation is F=1/2 (fan weight) * (maximum stroke opening/window height).
4. Power supply selection for electric window openers (which may slightly affect the price range)
The power supply used is AC220V, DC24V, etc. Use AC220V for daily ventilation; Use DC24V power supply when firefighting is required.
Anyway, the four elements of the selection table must be chosen according to the situation of different windows. 1. Instrument type; 2. Voltage usage; 3. Start the itinerary; 4. Pushing pressure, etc.
