The ventilation duct can convey fresh air and exhaust gas, discharge harmful gas outdoors, and convey outdoor fresh air indoors. Usually, the flow of the ventilation duct system is very large, so in order to save costs, it is appropriate to use ventilation ducts with small resistance. Galvanized iron pipes are generally used, and stainless steel air ducts are used in corrosive or particularly humid places.
1、 Air conditioning system: the ventilation pipe can be pasted with thermal insulation materials, and the surface is beautiful.
2、 Smoke exhaust system: The hotel, dining room and hotel kitchen often produce lampblack, which needs to be discharged. Therefore, it is advisable to use ventilation ducts with good strength and economy.
3、 Dust removal system: ventilation pipe can be used for collection and transportation of dust removal device.
4、 Bulk transportation: the type of air transportation system and several small and loose material particles can be transported by ventilation pipes, with low cost and good effect.
matters needing attention:
Shenyang ventilation pipeline
The ventilation mode of the basement shall be reasonably equipped with exhaust pipes and air outlets for ordinary ventilation, and shall also serve as smoke exhaust pipes and outlets in case of fire. The natural air intake from the driveway is considered in the basement, and the ordinary air supply system of other floors is also used as the air supplement system in case of fire. Avoid the air heat loss in the pipeline, and prevent the heat from radiating to the room, so that the room temperature rises. Do not touch the air duct to cause scalding.
In the early stage of building, the location of each pipe shall be designed, and the installation of ventilation pipes will ensure the quality of people's life. However, as time goes on, it will rust and produce the appearance of aging. Therefore, the managers of high-rise buildings should also regularly sort out the pipes and pay attention to extending the service life. Some special ventilation pipes: antirust coating may be selected for antirust protection, but when coating is used, the piping must be cleaned and evenly coated for antirust.
