In general, the balance of the fresh air system needs to meet the positive pressure requirements of the workshop. Reasonable calculations and allocations are made on a seasonal basis to avoid inconsistencies such as insufficient air volume, excess or negative pressure in the workshop. These problems are not enough to solve by the damper or the end regulating device. Therefore, under the premise that the cooling load meets the requirements of the refrigeration system of the textile industry, most of the advantages and disadvantages of the integrated efficiency depend on the return air system. Design, which is the rational design of the wind tunnel. It is closely related to the effective allocation of air volume, and the principle of energy conservation and reduction of initial capital is followed while ensuring the efficacy. In addition, the design of the pipeline should be closely coordinated with the architectural design to achieve a harmonious appearance.

1. The basic tasks of the air-conditioning return to the air duct design of the textile industry:

(1) Determine the position of the air duct and calculate the size of the air duct.

(2) Calculate the pressure loss of the air duct to select the fan.

(3) Selection and calculation of delivery and suction ports.

2. General requirements for the return of air duct materials and design and construction of textile industry air conditioners:

There are many types of materials that can be used as ventilation ducts. They are usually made of steel plates, and are made of aluminum plates and stainless steel plates. When anti-corrosion requirements are required, they should be made of FRP or composite materials. The return air ducts of the textile mills mostly use metal and non-metal ducts, brick or concrete trenches. Therefore, in the design and construction, you should pay attention to the following items:

(1) When the air duct is made of brick or concrete, in order to ensure the smooth inner wall, the method of brushing and lining the ceramic tile may be adopted, and the inner surface of the main air duct of the air supply shall be insulated and moisture-proof after being brushed, and When exiting while constructing, it is strictly forbidden to overflow the mortar.

(2) The cross-sectional shape of the air duct can be round or rectangular.

(3) The size of the air duct should be determined according to the provisions of the National General Ventilation Pipe Size Table formulated by China. If the conditions are limited, it can be calculated and determined.

(4) The design of the air duct and fittings should be convenient for construction, and the production and connection of the air duct should be kept tight.

(5) In order to prevent condensation and reduce the loss of cooling capacity in the duct wall, the air duct should be considered for thermal insulation.
