Compared with the traditional brick ventilation duct, the duct fan can save about 40% of the project cost and has a good fire protection function.
Why does the environment where the duct fan is located need temperature balance?
What are the product features of the duct fan?
How to ensure the safety of use of duct fans
The temperature balance of the ventilation duct is a very important link. Once the design is unreasonable, it is easy to cause the duct fan to rupture due to high or low temperature or prolonged exposure to a humid environment. Especially since the ventilation duct will bring a lot of heat, cooling and energy consumption during the operation, the temperature control structure of the ventilation duct is required to be high, which usually includes heat preservation, moisture-proof and protective layers. The thermal insulation layer is the core of the pipeline, the moisture-proof layer is to avoid the contact of the pipeline material with water and water vapor, and the protective layer is to protect the thermal insulation layer and the moisture-proof layer from damage.
1 For the ventilation system with noise reduction requirements, the duct fan with high efficiency and low impeller peripheral speed should be selected first, and it should work near the highest efficiency point. Corresponding noise reduction and vibration reduction measures should also be taken according to the transmission mode of noise and vibration generated by the ventilation system.
2. The duct fan changes the shape of the blade, so that the air flow has both axial flow and partial centrifugal effect after entering the fan, so its performance is between the axial fan and the centrifugal fan.
3. duct fans can provide medium air pressure and medium air volume, and are suitable for ventilation systems in high-rise civil buildings.
Common safety problems of duct fans: one is fire; the other is explosion. Therefore, when designing and installing duct fans, the first thing to do is to design for fire and explosion protection. On the other hand, when designing ventilation ducts, it is necessary to configure the safety system in advance. Once such a safety hazard occurs, it can be controlled directly through the system to avoid losses to industrial areas caused by disasters; on the other hand, it is necessary to design effective Safety monitoring system. Real-time monitoring of the operation of pipeline fans to ensure the safe operation of pipelines, and also provide an effective guarantee for safety early warning work in advance.
