How does the Air Duct Realize the Thermal Insulation?

Everyone engages in HVAC fabric duct system knows that there need to be a layer of rubber and plastic coated on the outside of the iron duct to play a role in heat insulation and prevent the cold air or hot air leaking from the iron duct from having a large temperature difference from the ambient temperature and causing condensation.


How does the cloth air duct realize the heat insulation?

First of all, the pre insulated air duct does not need insulation materials, the air duct depends on its own permeability to isolate the hot and cold air. The specific principle is as follows:


When the form of the central air conditioning is cooling or heating, we must choose the permeable fiber fabric as the air duct material. When sending cold air, under the effect of the pressure in the tube, the cold air will penetrate through the gap of the fiber and form a 360 ° airflow layer around the pipe, so that the cold air coming out of the pipe and the outside hot air will not touch on the wall of the air pipe, and there is no landing point and no condensation on the duct.


The air duct not only needs no extra duct insulation material but also has a variety of colors to choose from, which can be matched with various decoration styles.
