Little knowledge about window opener

The window opener is roughly divided into intelligent window opener and manual window opener.

1. Manual window opener

The purpose of manual window opener is to open the high-level ventilation window with some equipment. Due to the principle of thermal effect of air, hot air and light harmful gases that should be excluded cannot be effectively eliminated unless they pass through the high-level window.

Manual window opening usually takes 5 minutes: opening actuating parts (for example, cutting opening parts), corner connecting parts, operating parts, connecting rods and decorative covers. The window opening execution determines the window opening width, 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 the installation conditions different from the asynchronous type. The operating member may be in the form of a handle or lever. The handle is easy to operate and low cost. The output of the joystick operating parts is uniform, not easy to break, high machining precision and high cost.

For manual window opening application: it is mainly applicable to the internal window opening of the lower suspension and the external window opening of the upper suspension. Special external parts must be equipped on the external opening. From the analysis of the power on of the window opener, it is relatively labor-saving to open the window on the following page in the lower suspension. It is very laborious to open the outer window at the hinge position, so it should be noted that the quadruple bar must be used carefully. When the window is opened, the four-bar assembly will cause significant settlement of the center of gravity of the window, and if the weight of the window is very heavy, the force of the window equipment may not be enough to close the window.

2. Intelligent window opener

The simplest intelligent window opener only converts the mechanical window opener actuator into a motor and opens it. There are also gear window opening devices and chain window opening devices. However, due to the stability of the product and the requirements for service life, it is necessary to prevent dust, moisture and water before opening the window. The accumulation of dust will wear the window opener, moisture will rust the window opener, and water will short circuit the window opener circuit. The condensed water caused by the change of relative humidity in the room often occurs in buildings with poor thermal insulation performance of windows or changes in indoor environment, especially in greenhouse buildings. When choosing which window opener, it is very important to thoroughly analyze and understand the environmental conditions of the window opener.

Internationally, the imported window opener is completely sealed, dustproof, moisture-proof and waterproof. The thrust of the imported window opener can reach 1000 newtons, which is located at the bottom of the noise and has low power consumption. Since the installation conditions may be limited at the construction site, attention must be paid to the simplicity of installation.

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

Flue gas emission system is the latest fire fighting concept in the world, that is, when a fire occurs and smoke and heat are generated, the window of flue gas heat emission will open automatically. Modern architecture puts forward sufficient requirements for the fire protection of building materials, and gradually improves the fire protection performance of sexual materials obtained from fuel agents. Therefore, when on fire, smoke and harmful substances contained in it will be destroyed more directly. On the contrary, harmful smoke will interfere with active life-saving 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 lot of smoke and energy. It rises due to the heat of smoke and accumulates on buildings.
