Unit for processing air by means of controlled flow

Abstract

A unit for treating air with controlled flow, comprising a free rotor (GL), single or double inlet, combined with a directional conveyor (CD), which is designed so as to be able to directionally exploit the high static efficiencies, typical of free rotors (GL), and so as to be able to obtain the maximum optimisation between the power supplied and the static pressure obtained, at the same time maintaining low sound emissions, low dynamic pressure values at the discharge and no perturbation of the flow and of the performances both at the discharge and at the suction.

Description

technical field [0001] The invention relates to a unit for the treatment of air by means of controlled flow. [0002] In more detail, the invention relates to the application in general units intended to contain fans, or rather to the use of any free rotor, with single or double inlets in the conveyor in the corresponding direction, suitable for efficient conveying and Orientation of the airflow generated by the free rotor. Background technique [0003] In the field of ventilation and especially in air handling units UT, the use of free rotors, in other words without casings (Archimedean screws) CL, is known where the application requires it or allows it with their ventilation and dimensional characteristics Relevant (an example of a free rotor GL equipped with a front disc DAN and a rear disc DPO is illustrated in Figures 1A and 1B). [0004] Due to their widespread use, research and development has been carried out by various manufacturers over the past few years in orde...

Problems solved by technology

[0011] Therefore, it is presumed that if such a conventional rotor is used as a free rotor, due to the lack of interaction with the Archimedes screw, and, due to the lack of deflectors, the inevitable ventilation (AERAULIC) and acoustic delays occur, get bad performance

[0012] Free rotors are designed and developed on the one hand so that it is their own geometry, i.e. the lack of conventional Archimedean screws, that guarantees the highest possible static performance and efficiency (actually a characteristic of free rotors), and the same The geometry also allows avoiding ventilation and acoustic delays or at least attenuating them to a minimum (lack of existing diverters); however, on the other hand, there is no directional flow, but radial flow

[0013] Due to such differences and opposite properties, it is easy to understand how a conventional rotor cannot be used as a free rotor (due to the poor performance provided and the occurrence of delays), and vice versa, how a free rotor cannot be used in a conventional Archimedean screw , which in this case constitutes a hindrance during the operation of the device, with consequent non-optimal final performance
