Abstract

This work, through the outcomes obtained by a numerical analysis and the realization of a campaign of preliminary experimental measures inside some Air Traffic Control Towers different among themselves for size and type, has come to the conclusion that it is necessary to develop a new air distribution system inside a working environment and in a place where activities that require high levels of concentration, such as that of Air Traffic Control Tower’s , are performed. The analysis of how to optimize the thermo-hygrometric well being inside the operational environment of the air-traffic control towers was developed through a collaboration between ENAV S.p.A. and the Department of Technical Physics of the University of Rome “La Sapienza”. ENAV(National Body of Flight Assistance Italy) must guarantee the best working conditions in the operational rooms of Air Traffic Control Towers which are environments with a special geometry, constitution and with a particular activity inside: so there is the need to impose the establishment of general criteria that are also extremely precise for the technological systems they are provided with. For this purpose, the evaluation of the thermal working environment and, in particular, the identification of some environmental factors such as temperature, relative humidity, air velocity and the average radiant temperature of the walls, have an important role in the study. The microclimatic conditions obtained in the environment will guarantee conditions of thermal comfort through the evaluation of these parameters. The special configuration of the air-traffic control towers, the type of activity that is performed inside of their operational rooms and the presence of sophisticated electronic devices envisage a non traditional evaluation which uses a numerical analysis as the optimization tool of the parameters that are fundamental to obtain comfort conditions in the environment. The above mentioned numerical analysis applied in the designing phase allows the assessment of different types of air distribution systems, so to obtain the thermo-hygrometric comfort conditions in each corner of the occupied area. The performance of different terminals has also been verified in order to obtain a clean environment , keeping the maximum air velocity near the occupants under control. Some indexes listed in the law in force have been used to choose the position and the type of the terminals for the diffusion of the air: Draught Risk (DR), PMV, PPD, through which some useful information on the efficacy of the ventilation in the environment subject of this study has been gathered. Finally, the importance of the employment of thermo-fluid-dynamic simulations for the best design of an air distribution system for non conventional environments, like air-traffic control towers are, has been identified, allowing for the reduction of time and of the costs related to the designing phase.
