Résumé

This article is the Spanish translation of a paper presented at the 12th International Refrigeration and Air Conditioning Conference, Purdue University, USA (see the Bulletin of the IIR, reference 2010-1976). Optimum values of temperature and air flow velocity are desirable in a room for human comfort. Mechanical ventilation is an effective method to achieve this. These variables are affected by many parameters. The location of the inlet and the outlet duct play a pivotal role. This work aims at the numerical modelling of the room air flow phenomena when the inlet and outlet are placed at different locations in the room. Computational fluid dynamic (CFD) modelling of the air flow distribution is carried out in a mechanically ventilated enclosure that represents the scaled down model of a room. Turbulent regime of air flow is analyzed. The RNG k-E model is used to model the turbulent flow. Also, this work aims at suggesting the most ideal ventilation, which would provide comfortable room environment in winter season in coastal India. A commercial CFD package, FLUENT is used for the modelling of the various phenomena.
