Improving the working efficiency of ventilation duct hose and reducing energy losses are the ways to save energy. In some high-end residential buildings in developed cities, small household central ac spiral duct has become the basic configuration of the house and have been widely promoted. Then the usage of various ventilation and air conditioning duct hose has increased.
The basic functions of ventilation hoses mainly include
1. The ventilation hose transports air without producing noise. Or it has a noise elimination function.
2. The duct hose ensures that under the allowable pressure, the air will not leak ou.t Or the air outside the air duct will not invade inward.
3. Air vent hose has a long service life and it is easy to maintain
4. Transport hot and cold air to various required places in the building. Ensure that technical performance such as air temp, relative humidity, transfer speed and cleanliness remain unchanged. At present, there are many types of air ducts on the market. While the typical ones like nylon duct, high temp duct, PVC duct and PU duct hose.
In addition to iron ducts and fiberglass ducts, a new type of composite high-temp insulated duct HVAC industry.
High-temp insulated air ducts are mainly made of double-sided composite protective layers of insulation layers. While the insulation layers are mainly two types, foam and glass wool. Common duct boards are aluminum foil composite phenolic foam boards, aluminum foil composite PU foam boards, aluminum foil composite extruded polystyrene foam boards, etc. This type of air duct is ideal in terms of performance. Besides, it is light in weight, easy to construct and clean. Therefore, it has been used in many public civil buildings, including high-rise buildings.
