Shandong Institute of Commerce and Technology (Shandong Institute of Commerce and Technology) is a provincial vocational college approved by the Ministry of Education. The scope of design is the design of air duct of the cold air machine in the freezer.
1. MultiXair-S series D-shape semi-oval fabric duct system is adopted, with high permeability material to prevent frost formation on the surface of the system.
2. The chiller is composed of multiple fans in parallel. In order to reduce the impact and stabilize the air pressure of the system, a fabric plenum is designed for the part connected with the chiller. The wind speed in the plenum is lower than that of the duct, and part of the dynamic pressure is converted to static pressure, making the system more stable and balanced. It can also avoid the residual defrosting water blowing into the air duct and thus blowing into the material after defrosting. In order to facilitate the system deicing, the plenum is designed as an independent part and is connected with the chiller fan and the air duct by zipper.
3, the use of double row of track suspension system, fabric duct system at 3:9 to set the slide group, the track installed after the slide into the track slot can be set at the end of a separate track fixed, to prevent fan start and stop caused by the system movement.
4. The wind speed of the plenum is controlled at 4~6m/s, and the wind speed at the entrance of the fabric duct system is controlled at 8~10m/s.
5. The air supply mode is infiltration air supply and orifice air supply. The orifice is designed in S-shaped cross arrangement, and the air supply coverage is wider. In order to avoid dry consumption caused by cold air blowing materials directly, the orifice Angle is designed at 55~85 degrees.
MultiXair has accumulated experience in the design and implementation of fabric air ducts for various types of projects at home and abroad, and has summarized several sets of installation methods for different places. For more information, call 400-836-9929
