[Roof Fan]The role of roof fan Roof fan installation method
Many people do not know the importance of roof fans to our lives, here I personally for you Answer it. The magical role of roof fans in our daily life.
First of all, the roof fan is a kind of mechanical equipment that performs ventilation and ventilation operations on the roof. When you walk in the streets and look up inadvertently, you can often see the fans on the roofs of buildings, and sometimes you can hear the humming sound of the fans turning. It is more common especially in villages and towns.
Roof fans have been popular in people’s lives for a long time. They are installed at the top of buildings to induce and exhaust smoke. People generally call them induced draft fans. In fact, there are many types of roof fans. Among the roof fans, there is an axial flow fan that can be used for ventilation and smoke extraction of large air volumes, such as stadiums and high-level buildings.
Roof fan installation method
1. Many industrial plants, especially the color steel plate buildings, have poor heat dissipation conditions and are extremely hot in summer, resulting in low work efficiency. Product quality declines. The addition of low-noise roof fans can effectively improve indoor air quality, provide a comfortable working environment and increase work efficiency.
2. In many industries, due to the special nature of production, the air pollution in the factory is not only low in environmental quality, but in the long run, the health of employees will be harmed. However, low-noise axial-flow roof fans are installed to improve indoor ventilation, which can effectively protect the health of employees.
3. In many fire accidents, people are often choked by thick smoke. For example, installing a low-noise axial-flow roof fan can quickly discharge a large amount of smoke and give people more escape space, so it is Also a safety device.
Because you must pay attention to the installation method when installing the roof fan. Ensure the long-term availability and safety of the roof fan.
The role of the roof fan
1. The foundation for the installation of the roof fan must be higher than the roof, and the surface should be flat to prevent water seepage and leakage, and must be prepared beforehand. Bury the anchor bolts.
2. Add a layer of 5mm rubber sheet between the fan base and the foundation to reduce vibration. The anchor bolts should be equipped with spring washers to prevent loosening during use.
3. The diameter of the outlet of the roof fan can only be larger, not smaller. The last air outlet should be installed with an insect-proof net, and a weather cap should be added when the wind is biased upward; in case of snow in winter, the date of freezing , it must be started frequently to prevent heavy snow from blocking the fan outlet.
4. The roof fan and the air duct are connected by a hose (flexible material and non-combustible), the length should not be less than 200mm, and the pipe diameter should be the same as the inlet and outlet dimensions of the roof fan. In order to ensure that the hose will not be twisted and deformed during the operation of the system, it should be installed with an appropriate degree of tightness. For the canvas hose installed at the suction end of the roof fan, it can be installed slightly tighter to prevent the roof fan from being sucked in during operation and reduce the section size of the canvas hose.
