What problems should be paid attention to when selecting materials for ventilation ducts The material requirements in the air duct manufacturing process are very particular. When the air duct surface layer is made of aluminum foil, in order to ensure that the surface layer is not easy to be damaged, the aluminum foil material and thickness are specified, and the aluminum foil thickness of the air duct surface layer composed of aluminum foil and reinforcement material is also specified. Secondly, one of the basic conditions to ensure composite materials is that the inner and outer layers of the thin steel flange ventilation duct are firmly bonded to the internal thermal insulation materials. The plate defects exceeding a certain area not only affect the service life of the air duct

Two ventilation modes of ventilation pipe. Shenyang ventilation duct is a necessary device for ventilation in buildings to keep indoor air fresh and indoor humidity. The following are two ventilation modes introduced by Jiangsu ventilation duct manufacturer. Let's see what features they have. Dilution ventilation. Dilution ventilation is also called mixed ventilation, that is, to send air with lower concentration than indoor pollutants to mix with indoor air, so as to reduce the concentration of indoor pollutants and meet the health standards. Displacement ventilation. In displacement ventilation system

Function of ventilation duct in kitchen Shenyang ventilation pipeline can provide a better working environment for chefs. Because there are many people eating in the hotel, the air quality in the hall is also very poor. With Shenyang ventilation pipeline equipment, it can provide a good dining environment for consumers and leave a good impression on consumers. The corrosion resistance of Shenyang ventilation pipeline is just better than before, but in the process of processing, the iron sheet has high requirements for temperature and humidity in the air supply and return system, and the ultra clean system has medium efficiency filtration, which is easy to fall off, oil

What details should be paid attention to when cooling the ventilation duct Shenyang ventilation duct manufacturers use ventilation ducts to cool down the main stream of the factory workshop, so what details should be paid attention to when using ventilation ducts to cool down? 1. Ventilate and cool down. Because the sun shines on buildings, machinery, equipment, human body and other heat sources, the temperature of places requiring ventilation is higher than that of outdoor places. The negative pressure fan can quickly discharge the hot air in the room, so that the room temperature and the outside temperature are equal, and the temperature in the workshop will not rise. 2. Air flow takes away human body heat, air flow

What is the function of the exhaust hood of Shenyang ventilation duct? The local exhaust hood of Shenyang ventilation pipeline is used to catch harmful substances. Its performance has a direct impact on the technical and economic indicators of the local exhaust system. The local exhaust hood with good performance, such as the airtight hood, can obtain good working effect as long as the air volume is small. Due to different production equipment and operation, the exhaust hood has various forms. The ducts conveying gas in the ventilation system are called air ducts, which connect various equipment or components in the system as a whole. In order to improve the system

What will happen if the exhaust hood of Shenyang ventilation duct is not the right model? 1. The investigation results show that most of the users can choose the correct exhaust hood type, but there are also some wrong exhaust hood types. For example, a push table saw generates wood dust when sawing. Because of the large particle size and high specific gravity of wood dust, the wood dust generated during the push table sawing will fall to the ground after moving a short distance along the sawing streamline. In general, the lower suction hood should be used to control the wood dust generated by the push table saw, but the upper suction hood is used in the design
