Wind blowing perpendicular to a house can lead to a positive pressure along the windward side of a house and a negative pressure on the leeward side house causing air to enter the windward.
Poultry attic inlets.
Attics contain warm air that can be pulled into your houses during cold months to help cut heating costs.
First fresh air is introduced at the peak of the warm air produced by the heating system and birds tends to collect.
Unless properly installed and managed attic inlets can contribute to structural damage by allow ing warm and moist house air to enter and condense on trusses roof metal and insulation.
Poultry ceiling inlets attic air is typically warmer than outside air on cold days.
Some of the reasons why attic inlets are the preferred method of introducing fresh air into a poultry house in many cold climates include the following.
Chore time s attic inlets direct the incoming air along the ceiling of the poultry house for better mixing and to prevent downdrafts on birds.
1 since attic inlets draw air from the attic space and not from exterior side walls there is essentially no wind pressure on the inlets.
Double l attic or ceiling inlets take warm air from attic to heat living area of poultry house.
Reduce fuel consumption mixing warm air from the attic with house air during minimum ventilation reduces fuel consumption as compared to using cold air through sidewall inlets.
Attic inlets see figure below are used to recover solar heat from the atticof poultry houses.
It is critical to make sure incoming air is properly mixed with the barn environment to avoid chilling or not properly warming your animals.
Attic inlets tend to do a better job of conserving heat in a poultry house than conventional side wall inlets.
First fresh air is introduced at the peak of the warm air produced by the heating system and birds tends to collect.
Advantages of chore time s attic inlets in tests the total amount of air moved through a poultry house with attic inlets averaged 10 30 higher per day than houses with sidewall inlets only.
Poultry house attics are made up of trusses built with untreated lumber put together with press fit truss plates.
Attic and ceiling inlets represent an important component of your poultry or hog barn ventilation system.
The air that you and your chicken turkey etc.
Clean air is one of the most important parts of your poultry ventilation program.
By installing ceiling poultry inlets producers can capitalize on solar heat trapped in their attics and ventilate poultry houses more during the day.
The attic vent system is designed to be retrofit friendly in most drop ceiling poultry houses.
The large roof areas of dropped ceiling poultry houses make very good solar collectors so there is a large amount of heat readily available in the attic see the ther mal image below.
