In the hot summer, many companies have a headache for the uniform cooling of the high-temperature workshop of the factory. The traditional air duct used in the high-temperature workshop in the past has local low and local temperature. , It will cause serious physical discomfort, which will affect the company's normal production schedule and fail to deliver production tasks as expected. Now, in order to solve the problem of uniform cooling in the factory workshop, the fiber fabric air duct system came into being.

Insulation bag air duct is an air conveying and air distribution system made of fiber material. The system integrates static pressure box, insulation material, ventilation duct, tuyere and air valve into one, and uses the gaps in the fiber, as well as different forms of nozzles or slit air supply holes to send the airflow evenly and flexibly to the designated air supply. area. The waterfall thermal insulation cloth bag air duct has the characteristics of uniform air supply, large air volume, no blowing feeling, anti-condensation, easy to clean and maintain, healthy and environmentally friendly.

The thermal insulation bag air duct adopts the air outlet mode with displacement ventilation effect, and sends the fresh air that has been heat-humidified directly into the indoor personnel activity area. The fresh air flows downward with the convective airflow to form the dominant airflow of indoor air movement. The air exhaust outlet is set at the lower part of the workshop to remove the dirty polluted air, which belongs to the air distribution mode of "supply up and down discharge". Using this method, the temperature and humidity requirements of the factory workshop and the control of pollutant concentration are guaranteed.

The characteristics of the factory workshop are that pollutants are produced with the heat source, the space is tall, and the heat load is not too high. These characteristics just meet the requirements for the use of displacement ventilation. Different from the mixed dilution principle of traditional mixed ventilation, displacement ventilation is a ventilation method that sends fresh air at a lower wind speed into the personnel work area, and uses the principle of extrusion to squeeze polluted air into the upper space or the lower space for exhaust. The displacement ventilation method has advantages in terms of air exchange efficiency, ventilation efficiency, indoor air quality and energy saving, and has a relatively large potential for energy saving.

Displacement ventilation will involve many factors such as temperature distribution, concentration distribution, wind speed distribution, and airflow organization, making the design of displacement ventilation more difficult to grasp. Waterfall insulation cloth bag air duct has carried out in-depth research on the principle of displacement ventilation, and has carried out research and summary on the design method of insulation cloth bag air duct replacement ventilation, and uses advanced airflow simulation software and airflow simulation laboratory to support the design of displacement ventilation, which can control The temperature, humidity and pollutant concentration in the working area can be effectively controlled.

Insulation cloth bag air duct is a new type of ventilation. At present, it is being more and more widely used in factory workshops. The application results show that the air quality in the workshop has been significantly improved, and it can perfectly solve the problem of uniform cooling in the factory workshop. problem.
