Description

Technical field

The technical solution relates to textile tabs, as an end element, in particular to air handling devices, intended for as uniform an air outlet as possible.

Background Art

The prior art textile tabs, designed for uniform air discharge, consist of a fabric sewn into a hose shape which is adapted to achieve a uniform air discharge. That is, it is woven so as to pass a defined flow through a certain area or openings or slots in the airtight or at least breathable fabric. A combination of both is possible. Breathable fabrics are known in a number of breathability, from which to choose the closest to the desired parameters, that is, a square meter flow at a certain overpressure. The treated fabric is sewn into a hose shape, blinded at the end while keeping the airflow constant.

The disadvantage of this design lies in the fact that it is impossible to achieve precise flow rates and their easy change along and across the textile webs. It can only be made of a material of a certain degree of breathability and the combination of different materials is laborious. The need to select material from only a few degrees of breathability means a compromise to the desired flow.

Another disadvantage is the need for frequent washing because the air passing through the fabric will soon become dirty and clogged.

A significant disadvantage for the manufacturers of textile outlets is the need to store several breathable fabrics used to meet the airflow requirements. This leads to a high demand for the volume of the warehouse, which is also very expensive to maintain.

The essence of the technical solution

These drawbacks are largely removed by a textile outlet adapted to be attached to a duct or unit and provided with attachment elements to a suspension cable or rail formed by a fabric of a closed tubular shape into which apertures are formed according to the present invention. that the holes have a maximum diameter of 2 mm and the arrangement of the holes in terms of their exact number and density of perforation is determined by calculation depending on the demand for air flow along and around the textile tabs.

The main advantage is the possibility of using only a single breathability fabric, to which the precise, calculated number of small holes is adjusted. This ensures accurate flow according to the requirements of the HVAC designer. The openings are so small that the air coming out of them will soon merge into a single stream and produce the same effect as the air inlet through the breathable fabric. A small portion of the air also passes through the fabric to prevent any condensation of water on the surface of the ridges.

Another advantage is the prolongation of the diffuser maintenance interval because the holes are larger than the space between the fibers of the breathable fabric and the contamination will be slower.

The advantage is also seen in the possibility of varying the perforation density along the length or circumference of the tubular shape of the tabs. This increases the comfort of using the textile outlets, as the airflow can be adapted to the requirements of the installation site.

Examples of technical solutions

1 to 8, adapted to be attached to an air duct or unit and provided with elements 2 for attachment to a suspension cable 3 or bar, is formed by a fabric J. of a closed tubular shape into which openings 4 are formed. the diameter of 2 mm and the arrangement of the holes 4 in terms of their exact number and density of perforation is determined by calculation depending on the requirement of air flow along and around the periphery of the textile outlet. The openings 4o are circular but may be square or oval. The textile outlet is sewn into a closed shape, which is maintained by overpressure inside the outlet. The textile outlet is suspended by means of special elements 2, preferably made of hooks, which can be fixed in different amounts and at different points of the outlet. The hooks are suspended in the tensioned suspension cord 3, but can also be hung in the rail. Other suspension elements may also be used instead of hooks, such as snap hooks or continuously stitched reinforced strips. Holes 4 are formed in the fabric I, the size, shape and quantity of which correspond precisely to the calculation based on the flow and overpressure of the air. These openings 4 can be arbitrarily distributed around the circumference and length of the outlet according to the installation site conditions. Industrial usability

The micro-perforated textile outlet is industrially usable as a final element of air-handling equipment, intended for all areas with the need for ventilation, air-conditioning or hot-air heating.
