Inlet device with double exponential profile distributor for indoor air dispensation

This paper presents a device for introducing air inside a room with the novelty of double-exponential profile of the distributor. This allows entering the rooms of large quantities of blow-in air with low velocities, with the result of possible use in locations with a high required air exchange. In the Laboratory of Ventilation and Air Conditioning of the Technical University of Cluj-Napoca, it was designed and built an experimental stand in order to investigate the velocity field of a double-equal strength (double exponential profile) inlet device for spatial air-distribution. There are presented the measurements that were performed in the laboratory in order to establish the velocity field and the spatial distribution of air. The proposed solution can be used in many applications to provide high rates of air through the ventilation systems.
