What is the difference between ventilation hose and high temperature insulation air duct？
Improving the working efficiency of ventilation duct and reducing energy loss are the means of building energy saving. In some high-end civil residences in developed cities, small household central air-conditioning spiral ducts have become the basic configuration of houses and have been widely promoted, and the application of various ventilation and air-conditioning duct has increased.
The basic functions of the ventilation hose mainly include:
(1) The ventilation hose conveys air without generating noise, or has a noise reduction function;
(2) Ventilation hose ensure that the air in the air duct will not leak or the air outside the air duct will not invade under pressure-allowed conditions;
(3) The ventilation hose has a long service life and simple maintenance:
(4) Transfer hot and cold air to various places in the building to ensure that the technical performance of air temperature, relative humidity, transmission speed, and cleanliness are unchanged. Currently, there are many types of air duct in the market, except the traditional iron sheet. Aside from air ducts and glass fiber reinforced plastic ducts, a new type of composite high-blast insulation ducts made directly from insulation boards has begun to attract widespread attention in the building HVAC industry.
The high-temperature insulation air duct is mainly made of the double-sided composite protective layer of the thermal insulation layer, and the thermal insulation layer is mainly divided into two categories: foam and glass wool. Common air duct boards are aluminum foil composite phenolic foam board, aluminum foil composite polyurethane foam board, aluminum foil composite extruded polystyrene foam board, and insulation glass wool duct board. This type of duct is ideal in terms of performance, small thermal conductivity, light weight, easy construction, cleanliness, etc., and has been used in many public civil buildings, including high-rise buildings.
