This system is suitable in most regions with warm summers and cold winters. Air exchange in the barn occurs by the natural ventilation principle. The Natural ventilation system is most suited for mid-sized to small-sized barns due to the physical restrictions of the ventilation principle.
System – winter
Warm air generated by the cows rises and exits through the adjustable chimneys in an airflow pattern called the “chimney” effect. The warm rising air creates a vacuum that lets in fresh, colder air from the adjustable side curtains. Adjustable chimneys ensure the correct air exchange for optimal inside climate conditions.
System – summer
The lack of a “chimney” effect in warmer periods means that most of the air exchange is created by the wind pushing air through the curtain openings. Curtains and chimneys will be entirely open to facilitate as much air exchange as possible. For safety measures, the curtains will close in the case of strong winds and rainfall. Recirculation fans can be added to the system for cooling in warm periods. A high-pressure cooling system can be added for additional cooling. This reduces the air temperature directed across the stalls for increased cooling in combination with airspeed from the recirculation fans.
