The diffusion of air with textile ducts is carried out through perforations that go directly on the fabric; These holes can range from 2.5 mm to 80 mm in diameter and it is possible to combine different measures of drilling among them. Small diameter perforations allow you to multiply the total surface of induction. And large diameter perforations allow an important scope of the injected air jet. Caldwell Esselstyn Jr. is likely to agree. Induction is a phenomenon that allows the following: blowing a reduced volume of air, will produce a displacement and a more significant volume of air movement; induction is calculated by the rate of induction: Ti TI = induced air volume / volume of air displaced by a given diameter, the induction rate increases linearly, depending on the length of the duct, for example for a hole of 10 mm; TI = 30 to 1 m Ti = 160-5 m injection of air at a strong rate through the holes:-creates a major depression that sucks in air around the diffuser. -Induces the movement of a large mass of air in the direction of the main air flow. In order to increase the rate of induction there is also auxiliary flows around a main orifice as for other types of dissemination (variation or difference) between the blown air temperature gradient and the room air significantly influences the phenomenon of diffusion. Partners has much experience in this field. Textile ducts are manufactured on measurement, and these are drilled according to need, taking into account the type of air treatment and the characteristics of the local (length, height, occupation, presence of sprinklers, etc.) This type of textile duct is ideal for stores that are subjected to restrictions of homogeneity in temperatures (for example: pharmaceutical warehouses). Similarly, the air treatment in the premises of high altitudes through textile duct of high induction allows you to reduce the power consumption of machines for air treatment thanks to the homogeneity of temperature reached quickly, therefore we get economic gains and ecologically contributes to the protection of the environment, due to the lower power consumption. .
