Little knowledge about window openers

Window openers are roughly divided into intelligent window openers and manual window openers.

1. Manual window opener

The purpose of a manual window opener is to open a high-level ventilation window using a certain device. Due to the principle of thermal effect of air, it is not possible to effectively eliminate the hot air and light harmful gases that should be eliminated unless through a high-level window.

Manual window opening usually takes 5 minutes: opening execution components (such as cutting opening components), corner connection components, operating components, connecting rods, and decorative covers. Determine the width of the window opening, the load of the window opening device, and whether there is a locking function. The angular connection part is a transmission part, and its deformation determines the ability of the open-loop device to adapt to installation conditions different from asynchronous types. The operating component can be in the form of a handle or lever. The handle is easy to operate and has low cost. The output of the joystick type operating component is uniform, not easy to break, with high machining accuracy and high cost.

For manual window opening applications: mainly suitable for internal windows with lower suspension and external windows with upper suspension. Special external components must be equipped on the external opening. From the analysis of the power on situation of the window opener, it is relatively effortless to open the window on the lower page in the lower suspension. It is difficult to open the external window at the joint position, and attention should be paid to using the quadruple bar carefully. When the window is opened, the four-bar assembly can cause significant settling of the center of gravity of the window, and if the weight of the window is heavy, the force of the window device may not be sufficient to close the window.

2. Intelligent window opener

The simplest intelligent window opener simply converts the mechanical window opening actuator into an electric motor and opens it. There are also gear type window opening devices and chain type window opening devices. However, due to the stability of the product and the requirements for its service life, dust, moisture, and water resistance are necessary to open windows. The accumulation of dust will wear down the window opener, moisture will rust the window opener, and water will short-circuit the window opener circuit. The condensation caused by changes in relative humidity in the room often occurs in buildings with poor insulation performance of windows or changes in indoor environment, especially in greenhouse buildings. It is very important to conduct a thorough analysis and understanding of the environmental conditions of the window opener when choosing which one to use.

Internationally, imported window openers are completely sealed to prevent dust, moisture, and water. The thrust of the imported window opener can reach 1000 Newtons, located at the bottom of the noise, and has low power consumption. Due to possible limitations on installation conditions at the construction site, it is necessary to pay attention to the simplicity of installation.

There are currently two types of automatic control systems for electrical switches. The house control system is a system that controls the opening and closing of doors and windows by comparing measured values of temperature, humidity, sunlight intensity, wind intensity, and rainfall level with preset values.

Smoke exhaust system is the latest development in international firefighting concept, which means that when a fire occurs and produces smoke and heat, the window for smoke exhaust heat release will automatically open. Modern architecture has put forward sufficient requirements for the fire resistance of building materials, gradually improving the fire resistance of materials with sexual desire obtained from fuel agents. Therefore, when caught on fire, the smoke and harmful substances contained therein will be more directly destroyed. On the contrary, harmful smoke can interfere with active rescue and passive escape behavior. From the study of the development process of fire, it can be seen that from the stage of fire outbreak, there is a large amount of smoke and energy. It rises and gathers on buildings due to the heat of smoke.
