The typical feature of a tunnel ventilation system is the fans installed in the rear gable of a house and an air inlet at the front of the house, or vice versa. This configuration causes the so-called tunnel effect where air flows over the animals at great speed. This air flow creates a cooling breeze.
Windchill effect with tunnel ventilation
The high air velocities that occur with tunnel ventilation extract heat from the body surface of the animals. That is the so-called windchill effect. With a wind speed of 1.5 meters per second, like a sea breeze, that windchill effect can ensure that the actual house temperature of 34 degrees Celsius feels like 24 degrees. In this way the cooling effect of a high air velocity can be used to avoid heat stress.
Tunnel ventilation ideal at high temperatures
This tunnel ventilation system is used in regions with high temperatures. The precision control can adapt the air speed in the house to the temperature in the house and the age of the animals. This ensures the animals stay in their comfort zone and that their feed and water consumption patterns are not affected. Tunnel ventilation safeguards uninterrupted growth of your animals.
Tunnel ventilation system with PAD cooling
In extremely hot weather conditions, the tunnel ventilation system can be supplemented with Greenline controllable PAD cooling to prevent heat stress. This system uses cooling units that cool the incoming air using water that flows through a synthetic pad installed in front of the air inlet. A major benefit of this cooling method is its capability to cool air to 7 degrees Celsius, coupled with extremely low energy consumption. A unique feature of the Greenline pad cooling is the controllable cooling capacity. This means that conditions in the house will be accurately regulated to suit the needs of the animals and prevents temperature fluctuations.
