Numerical Analysis Of Micro-ventilation System In A Wine Cellar

The importance of internal environmental conditions in a wine cellar is well known and investigated. The process of wine preparation consists in several steps, where temperature and humidity play a fundamental role, since the quality of the final products is strongly affected by constant and suitable environmental conditions. However, various critical factors have emerged, such as mold growth or wine losses, where ventilation has proved to be insufficient or poorly designed. Considering these, the addiction of a mechanical ventilation system, consisting in a perforated tube provided by a small fan, has been considered to support the possible lack of natural ventilation. The comparison between the two cellar congurations has been carried out through CFD modeling of the indoor air and temperature distributions in the room, in two different periods of the year when the natural ventilation is differently performed.
