Founded in 1947, the Group is a leading port services and food group in Asia and was listed on the SGX in 2000. "Xinxiang Lelian (Tianjin) Food Co., LTD." is the second large central kitchen that Xinxiang Group has entered the Chinese market. It is committed to building a large central kitchen with full cold chain with advanced design concepts and highly mechanized equipment. The Tianjin project covers an area of 30 mu, with a total construction area of 20,000 square meters.


First, the scope of design: cold kitchen air conditioning unit fabric duct system design.


Second, MultiXair fabric duct air supply system design


1. MultiXair high permeability material is used 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, Adopt MultiXair-S series oval fabric duct, fabric duct system width 1200mm, height 400mm.


4, the use of 3 rows of wire rope suspension system, hanging point at 3 o 'clock 9 o 'clock and 12 o 'clock three rows, stick to the top hanging, the end of the hanging point is set, stretching fixed to prevent the fan start and stop the end of the movement.


5. 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.


6. 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 30~75 degrees.


7. The inlet section of the fabric air duct system is set in the air outlet of the cooler and is tightly connected with the hoop.


Three, fabric duct real shooting

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
