As a rule, ventilation in the barn is required for the owners using it as a chicken coop, a barn. In winter, birds or animals are constantly in the barn. The products of their vital activity emit ammonia, and they themselves exhale carbon dioxide in huge quantities. A simple airing of the shed is impossible when there are twenty-degree frosts on the street. Therefore, zealous owners provide cattle with fresh air, equipping ventilation in the barn with their own hands.
How to make ventilation in the barn
Before you make ventilation in the barn, you should start with the insulation of the room. Not insulated walls become damp, condensation is collected on them. Even the presence of ventilation does not save the situation. If in the winter time the shed is heated, there will simply be nothing to breathe in it without ventilation. The easiest and cheapest way to equip a shed ventilation with your own hands is a natural inflow and blowing.
Pipes of large diameter (10 - 15 cm) are suitable as air ducts; they can be of any section (round or square). Pipe connections should be sealed, otherwise there will be no traction.
The flow of fresh air into the barn is provided by the outlet of the pipe to the street at the level of the floor of the barn.
For outflow, holes are made in the three corners of the ceiling and pipes are inserted. They should fall below the ceiling level by about 25-30 centimeters. You can put on the sewer adapter on the pipe outlets, so that two pipes will exit horizontally in different directions. The outlet of the exhaust pipes should be closed with special covers - umbrellas, so that they do not drip water and snow does not fall.
Carbon dioxide and ammonia are collected under the ceiling and pulled out through openings. And from the bottom pipe, fresh air enters the barn room.
Forced ventilation shed
Forced ventilation in the barn is even easier to organize. But the room must have a power source. A conventional cooker hood without filter is mounted. Such models are equipped with an exhaust fan blowing air from the room into the ventilation system. In the shed, it is necessary to bring the pipe out, and connect the inner end to the hood. If the room contains chickens, it is advisable to cover the exhaust outlet with a net.
After ventilation is done in the shed, it is necessary to check it for drafts. They are very harmful to any livestock and birds. And in winter to regulate the temperature in the chicken coop, a plug is installed on the inlet of the influx pipe. It can be removed at any time or slightly pushed, leaving a very small gap.
