It’s a good choice to improve the working efficiency of ventilation duct and reduce energy loss to save energy. In some high-end buildings, small household central ac spiral ducts have become first choice. And it is more and more popular. As a result, the use of various ventilation hose and ac ducts has increased.
The basic functions of ventilation hose mainly include
1.The duct hose transports air without producing noise. Or it has a silencing function;
2.The hose ensures that the air in the air duct will not leak out or the air outside the air duct will not intrude.
3.The ventilation hose has a long service life and it is easy to maintain
4.Transport hot and cold air to various places in the building. And it ensures that air temp, relative humidity, transfer speed and cleanliness remain unchanged. Currently, there are many types of air ducts in the market. In addition to iron sheets and FRP air ducts, a new type of composite high-temp insulated air duct comes.
High-temp insulated air ventilation duct is mainly made of double-sided composite protective layers of insulation layers. While the insulation layers are mainly foam and glass wool. Common duct boards are aluminum foil composite phenolic foam boards, etc. But this type of air duct performs well. Because it is a clean material which is light in weight and easy to operate. Now, it widely serves in various buildings.
