通风管道与传统风管比较的优势
Advantages of ventilation ducts compared to traditional ducts
通风管道在实践的运用中仍是有很多点需求咱们引起留意的，从本钱上考虑，管道的高宽比例应该小于1:3，在规划的过程中也要尽量减少照耀部位的数量。对风管设备的持久性影响最大是密封材料，要选择运用复合通风管道要求的配件，并按照要求来操作。在设备的过程中也要尽量留神，以避免形成丢掉。通风管道是替代铁皮风管和玻璃纤维风管的新一代环保节能型风管，通风管道是由多种混合材料加工制作成的，包含酚醛、玻镁等风管，因为通风管道有酚醛、聚氨脂和挤塑等几种，都是外层为压花铝箔掩盖内部为发泡夹层的办法。这几种风管都不需求再做任何保温处理。联接办法都是选用法兰联接，这种法兰有较好隔功用，所以也不需求另做保温。
There are still many points that we need to pay attention to in the practical application of ventilation ducts. From a cost perspective, the height to width ratio of the ducts should be less than 1:3, and the number of illuminated areas should also be minimized during the planning process. The biggest impact on the durability of air duct equipment is the sealing material. It is necessary to choose accessories that meet the requirements of composite ventilation ducts and operate them according to the requirements. During the equipment process, it is also important to be as careful as possible to avoid loss. Ventilation ducts are a new generation of environmentally friendly and energy-saving air ducts that replace iron sheet air ducts and fiberglass air ducts. Ventilation ducts are made from a variety of mixed materials, including phenolic, magnesium glass, and other air ducts. Ventilation ducts include phenolic, polyurethane, and extruded plastic, all of which are covered by embossed aluminum foil on the outer layer and foam interlayer on the inner layer. These types of air ducts do not require any further insulation treatment. The connection method is to use flange connection, which has good insulation function, so there is no need for additional insulation.

中央空调传统送风管道一般内层选用铁皮 天津通风管道或玻璃钢，外裹保温材料，最外面用铝箔进行盘绕，这使得送风管自严重、施工设备费工费时、外观差、气密性低、能耗大。与传统风管比较，酚醛通风管道具有以下优势：1.绝性好，可大大减少空调的散丢掉酚醛通风管道的导系数，而镀锌钢板风管和玻璃钢风管的导系数大得多。其他，酚醛通风管道特有的联接办法确保了通风系统优异的气密性，靠近镀锌钢板风管。有材料标明，在运送相同量时，镀锌钢板风管的散丢掉为，玻璃钢风管的散丢掉为，酚醛泡沫保温材料风管的散丢掉低于。消声性定网站建设  伺服液位仪  防撞墙模具 唐山护栏 遮阳网 风电基础模具好酚醛铝箔通风管道壁的夹层为互相贯穿的多孔酚醛泡沫材料板，具有杰出的消声功用。在中央空调系统中，经过送风管道传递，构成室内噪声。
The traditional air supply pipes for central air conditioning generally use iron sheet Tianjin ventilation pipes or fiberglass as the inner layer, wrapped with insulation material, and wound with aluminum foil at the outer layer. This results in severe self damage, time-consuming construction equipment, poor appearance, low air tightness, and high energy consumption of the air supply pipes. Compared with traditional air ducts, phenolic ventilation ducts have the following advantages: 1. They have good insulation and can greatly reduce the scattering of air conditioning. The conductivity of phenolic ventilation ducts is much higher than that of galvanized steel sheet air ducts and fiberglass air ducts. In addition, the unique connection method of phenolic ventilation ducts ensures excellent airtightness of the ventilation system, close to galvanized steel duct. It is indicated by materials that, when transporting the same amount, the loss of galvanized steel sheet air duct is, the loss of glass fiber reinforced plastic air duct is, and the loss of phenolic foam insulation material air duct is lower than. The interlayer of phenolic aluminum foil ventilation pipe wall with good noise elimination performance is a porous phenolic foam material board that penetrates each other, which has outstanding noise elimination function. In the central air conditioning system, indoor noise is transmitted through air supply ducts.
