Selection of booster fans
Thread Content
Dear sea friends, we are currently facing a situation: the weather is very hot, and the factory has portable air conditioners. However, for a specific purpose, it is necessary to channel the cool air from these air conditioners through PVC transparent hoses into the chemical protective suits of the workers in order to cool them down. The air conditioning system has an exhaust volume of 1550 m³/h, with a pressure of around 0.5 bar (it might even be less). Previously, a hose 20 meters long with a diameter of 1 inch was used for testing, and the outlet air pressure turned out to be very low ； Subsequently, the booster fan was tested again with a static pressure increase of 380 Pa and an air volume of 580 m³/h, but the outlet wind pressure remained very low. Are there any other good ways to solve this problem? Thank you:handshake
Hello, based on the situation you described, the following aspects may need to be considered in order to improve the efficiency of the system: 1. **Diameter and length of the pipes**: Too small a diameter or too long a pipe length can result in significant pressure losses. Try using a hose with a larger diameter to reduce resistance and pressure loss. For example, increasing it to 2 inches or larger can effectively improve air flow. 2. **Fan selection**: It may be necessary to choose a fan with higher airflow and static pressure. The static pressure of 380 Pa of the booster fan you are currently using may not be sufficient to overcome all the resistance losses in the piping. It is recommended to find a fan with a higher static pressure for testing. 3. **Reduce pipe bends**: Minimize the number of bends and their severity, as each bend results in additional pressure loss. 4. **Check for air leaks at connections**: Ensure that all connections are airtight; air leaks can significantly affect the system’s pressure and efficiency. 5. **Intermediate pressurization**: If conditions permit, an additional pressurization fan can be installed at a midpoint in the pipeline to increase pressure in segments, which is particularly effective for long-distance transportation. Through the above improvements, the transmission efficiency of air conditioning coolant in the hoses should be effectively enhanced. I hope these suggestions are helpful to you! .
This thing has existed since the era of nucleic acids; it features a small fan attached to it, with coils inside. Water-cooled. Also, good ventilation – is your portable air conditioner actually an air conditioner? Dry air or humid air? It’s better to avoid using that kind of humid air conditioning.
Mobile air conditioners use dry air. Haiyou, do you have the contact information of the supplier who provides these protective suits?
Well, I am indeed looking for a booster pump with higher wind pressure; the pipe diameter and such might not be changeable. Thank you
