Several Kinds of Common Wind Patterns and Applicable Places of Cloth Air Duct

  1. Porous air outlet mode. It is the air outlet mode that the air volume is delivered to the ventilation area from a row of orifices. The wind speed of this mode is about 0.3~0.8m/s; the characteristics are that the orifices are arranged in a row orderly with the same diameter of single row orifices , the air diffuser covers a wide range, and the air flow is uniform. It is mainly used in supermarket,  production workshop , food workshop, logistics, storage and so on.

 

  1. Large orifice air outflow mode. It is the air outlet mode that the air volume is transmitted from the large-scale orifice to the air sockventilation area. The wind speed of this mode is about 0.5~1.5m/s, characterized by large orifice diameter (diameter above φ 40mm) and large air supply volume. It is mainly used for air diffuse in the workshop.

 

  1. Outlet air mode. It is the air duct diffusermode that the air volume is transmitted from multiple outlets to the ventilation area. The wind speed of this mode is about 0.3~0.8m/s, characterized by small and the same orifice diameter (diameter under φ 30mm), large number and uniform air flow. It is mainly used in places with large air volume, small space, and high air exchange rates, such as greenhouse and so on.

 

  1. Jet air outlet mode. It is the air diffuse mode that the air volume is delivered from the nozzle to the ventilation area. The wind speed of this mode is about 0.8~2m/s, which is characterized by high wind speed and long air supply distance. It is mainly used in large workshops and other places.

 

  1. Mesh air flow out mode. It refers to the air supply mode that the air volume is sent to the ventilation area by the long grid. The wind speed of this mode is about 0.2~0.3m/s, characterized by low wind speed, specific wind direction, and uniform air flow. It is mainly used in swimming pools and other places with anti condensation design.

 

  1. Permeate air outlet mode. It refers to the air supply mode that all air volume penetrates from the fiber fabric surface was sent to the ventilation area. The wind speed of this mode is slower than 0.2m/s, characterized by low wind speed, uniform air flow and small temperature gradient. It is mainly used in cold storage, fruit cold storage workshop, electronic workshop, and other places.
