2.Cattle house new wind flexible fabric
cloth duct system design
1) Engineering requirements
The cows house have a span of more than
26m. In the winter, positive pressure should be used to transport fresh air to
avoid the lack of oxygen to affect the growth of the cattle, and to ensure
uniform air supply in the active area of the cattle.
2) Winter fresh air volume calculation table:
Q (ventilation amount) = length of barn *
width of barn * height of barn * number of air changes;
According to the span, height,
installation and other issues of the barn, it is necessary to consider the
flexible air duct layout and the number of fans;
3. Design of flexible fabric cloth duct
system of cow house
1) Layout design of flexible fabric cloth
duct system
The axial flow fan is installed outside
the barn. The Liangmo fabric duct system is according to the barn span and the
position of the cow bed,wind duct located at the mountable height position of
the cow bed . The height can be adjusted according to the site conditions.
4.）Design of air outlet mode of flexible
fabric cloth duct system
The air outlet mode is designed to have a
small hole air outlet mode, and the system small hole air flow organization
form is based on the air flow convection principle, and the small hole air
outlet is sent to the target area at a certain wind speed for heat exchange to
achieve heating requirements. Suitable for heating, fresh air and cooling. The
arrangement of the venting holes should be evenly divided into two rows at the
lower end of the venting duct, just like the 5 and 7 o'clock of the clock.
Airflow organization distribution curve
5.) Advantages of flexible fabric cloth
duct system:
Economic
Low total investment: no insulation, no
diffuser, no muffler, integrated multiple units, low installation cost, saving
9.8% investmentLow operating costs: energy-saving operation, energy consumption
is 74% of traditional ductsLow cleaning costs: 2% of traditional ducts
Comfort
Air supply effect: the air supply effect
is formed by the gap of the fabric and the air supply of the opening, and the
air volume is large and the wind is not felt.
Aesthetics: You can order a variety of
colors, no longer a single color. You can also customize the patterns and
slogans that you like.
Cleanliness: The duct can be easily
disassembled and installed, which is very convenient to clean and improve the
cleanliness level in the system.
Feature
Environmental protection: The materials
are environmentally friendly and recyclable materials. They are manufactured
and installed in accordance with environmental protection requirements. The
entire system is very energy efficient.
Anti-condensation: through the integral
duct fiber gap filter the cold air, forming a cold gas layer outside the duct
wall, no temperature difference inside and outside the duct ,completely solve
the problem of duct condensation.
Reduce noise: the air duct system is soft
in material, low wind speed in running , no noise is generated and transmitted,
very quiet.

the fire during transportation, installation, and operation of this product;
3. if the product
is used for 12 months, if any dirt, it can be cleaned;
4. Please protect
the product when installing the air duct, prevent the toughness tool from
scratching the product, and bring the gloves to avoid soiling the product;
5. the air duct is
correctly installed to prevent the rat and other animals from biting, preventing
other tough tools from smashing, avoiding heavy pressure and stretching;
6. the air
conditioner is turned on, first open the lowest gear to make the air duct
inflated, and then gradually adjust to the maximum gear position, to avoid tear
the air duct due to the instantaneous tension;
7. When the air
conditioner is not turned on for a long time, the air duct should be removed,
dried and stored in a dry environment to avoid mildew caused by environmental
humidity (if occoured, the manufacturer is not responsible).
