Natural ventilation for the milking areas (cows, buffalos, sheeps and goats)
PLANTS FOR THE MICROCLIMATIC CONTROL
The natural ventilation in a shelter is the ventilation originated from the different density of the indoor air (hotter) respect to the outdoor air (cooler). With an over-roof and openings on the side walls, at a lower level, there is a natural circulation of air that enters from the windows and goes out from the opening on the roof.
The air change inside the shelters can be obtained with two main systems: natural ventilation and forced ventilation.
NATURAL VENTILATION FOR THE MILKING AREAS
Besides the difference of the indoor and outdoor temperature, the wind is another natural force that can create an air movement. Therefore it is essential that the orientation and the position of the shelter together with the control of the openings are suitable to exploit the sinergy of these two natural forces.
From the building point of view, the several solutions studied in order to avoid the disadvantages due to this ventilation system are:
- the position of deflectors near the openings , to reduce the negative influence of the wind, especially during winter;
- the construction of windows and openings (windows and over-roof) easily controlled by an automatic gearcase;
