During the hot summer days, many enterprises have headaches because the factory's high-temperature workshop cools down evenly. In the past, traditional air ducts used in high-temperature workshops had low local temperatures and high local temperatures. When working in the indoor environment, the personnel working in the room will feel severe physical discomfort, which will affect the company's normal production schedule and fail to deliver the production as expected. Now, in order to achieve uniform cooling of the factory floor, the fiber fabric air duct system came into being.
Insulation sox air duct is an air delivery and air flow distribution system woven from fiber material. The system integrates static pressure box, thermal insulation material, ventilation duct, tuyere and air valve into one, using the permeability of the fiber and different forms of nozzles or slit air supply holes to send the airflow uniformly and flexibly to the designated wind area. The heat preservation bag air duct has the characteristics of uniform air supply, large air volume, no blowing feeling, anti-condensation, easy cleaning and maintenance, health and environmental protection.
The insulation sox air duct adopts the air outlet mode with replacement ventilation effect, and the fresh air after heat and humidity treatment is directly sent to the indoor personnel activity area, and the fresh air flows downward with the convection air flow to form the dominant air flow of indoor air movement. The exhaust vent is set in the lower part of the workshop to remove the dirty polluted air. This belongs to the " delivering upward and discharging downward" air distribution method. In this way, the temperature and humidity requirements and the control of pollutant concentration in the factory workshop are guaranteed.
The characteristics of the factory workshop are that the pollutants are accompanied by heat sources, the space is large, and the heat load is not too high. These characteristics just meet the requirements of replacement ventilation. Different from the mixing and dilution principle of traditional mixed ventilation, displacement ventilation is a ventilation method that sends fresh air at a lower wind speed into the work area of the personnel and uses the principle of squeezing to squeeze the polluted air into the upper space or the lower space and discharge it. The replacement ventilation method has advantages in terms of air exchange efficiency, ventilation efficiency, indoor air quality, and energy saving, and the energy saving potential is relatively large.
For factory ventilation, displacement ventilation will involve many factors such as temperature distribution, concentration distribution, wind speed distribution, air flow organization, making the design of displacement ventilation more difficult to grasp. The design of the heat preservation sox air duct is an in-depth study on the principle of displacement ventilation. Research and summary of the replacement ventilation design method of the insulation sox air duct, and the use of advanced airflow simulation software and airflow simulation laboratory to support the replacement ventilation design, can effectively control the temperature and humidity of the work area and the concentration of pollutants.
Insulation sox air duct is a new type of ventilation method. 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 that the factory workshop cannot be cooled uniformly.
