I have heard it said that the air inlet is the most important part of my ventilation system. How can air inlets be more important than fans?
At least in times when birds are young and/or weather is cool, so we are running in either minimum or transitional ventilation modes, you could make a good argument that the inlets are the key to getting the job done. Of course fans must be running, and they provide the muscle for the system. But in modern negative-pressure poultry houses the air inlet provides direction. Using a static pressure sensor, the inlets adjust themselves to direct cold, incoming air into the house in such a manner that does not cause condensation or bird chilling. A properly designed modern house with static pressure-controlled inlets will bring cold air into the house at high velocity and high above the birds so that the cold outside air mixes with the warm air in the top of the poultry house to achieve the desired temperature before contacting birds. Without proper air inlets or with air inlets being used improperly, either not enough air will come in, or outside air will come into the house too slowly and
