Design calculations for "micro ducts"

Introduction of graphs related to acoustic design calculations, resistance calculations, and airtightness calculations, as well as the formulas used.

"Micro Duct" is a product that excels in sound absorption, thermal insulation, and airtightness, allowing for the completion of duct work, sound absorption work, and insulation work in one process, thereby enabling a reduction in construction time. Details of the acoustic design calculations, resistance calculations, and airtightness calculations for this product are introduced in the downloadable materials (comprehensive catalog). Please be sure to check it out. [Contents (excerpt)] ■ Acoustic Design Calculations - Noise generated by the blower - Acoustic attenuation of the silencer chamber - Acoustic attenuation of the silencer elbow, etc. ■ Resistance Calculations - Calculation formula for pressure loss in the straight section of the micro duct - Calculation examples (friction resistance of the straight section / pressure loss of the bend / pressure loss at the branch) ■ Airtightness Calculations - Calculation formula for total leakage air volume during ventilation - Calculation examples *For more details, please refer to the materials or feel free to contact us.
