Airflow Fundamentals

Distribution of Air Conditioning Outlets

The purpose of the experimental and computational study of air distribution vents with air grilles, manufactured by Ventus is to acknowledge and develop the appropriate operating range of air grilles and the fundamental values that characterize them. The study took place at the Laboratory of fluid dynamics at the University of Patra, under the supervision of Mr. Dionysios-Eleftherios Margaris. Every air-conditioned area should be ventilated evenly to avoid any discomfort caused by temperature changes or air velocity. The following table shows the range of optimum air velocity depending on the application.

Room Air Velocity (m/s) Persons Reactions Application
0-0.08 Sweltering environment None
0.13 Optimal speed Everywhere
0.25 Maximum tolerated speed for individual sitting space Everywhere
0.33 Adverse Several
0.38 Maximum limit per person moving in a space Commercial shops
0.38-1.52 High air speeds Only Industrial

Characteristics

The aspects that characterize each air outlet in order to ensure the desired conditions for the intended application are:
