The specific difference between ventilation hose and high temperature insulation duct
Improve the efficiency of ventilation ducts, reduce energy loss is the means of building energy saving. In some developed cities in the high-grade civil housing, small home central air conditioning spiral duct into the basic configuration of the house to promote a large number of various ventilation and air conditioning duct application volume increased.
The basic functions of the ventilation hose mainly include.
(1) ventilation hose conveying air does not produce noise, or both anechoic function;
(2) ventilation hose to ensure that the air duct in the allowable pressure conditions, the air inside the duct will not leak or air outside the duct will not intrude;
(3) Ventilation hose has a long service life and simple maintenance:
(4) conveying hot and cold air to the various places in the building need to ensure that the air temperature, relative humidity, transfer speed and cleanliness and other technical properties remain unchanged At present, there are a variety of types of air ducts in the market applications, in addition to the traditional tin duct and fiberglass duct, a new composite high plague insulation duct made directly with insulation panels began to attract widespread attention in the building HVAC industry.
High temperature insulation duct is mainly made of insulation layer double-sided composite protection layer, insulation layer and mainly divided into two categories of foam and glass wool. Common air duct board for aluminum foil composite phenolic foam board, aluminum foil composite polyurethane foam board, aluminum foil composite extruded polystyrene foam board, insulation glass wool air duct board and so on. These ducts are ideal in terms of performance, small thermal conductivity, light weight, easy construction, clean, etc. They have been used in many public civil buildings, including high-rise buildings.
