Ventilation-cellar-with their own hands
A rare phenomenon when there is not a single basement in a private house. The room where you can store products, equip a warehouse, a workshop, a games room, a gym, etc.- the functions of cellars can be listed for a long time. It is important to maintain in the cellars certain conditions suitable for a particular purpose. Excessive dampness in the room will do just that for growing mushrooms. If the basement is not intended for growing mushrooms, it is simply necessary to exclude in them increased dampness, to seal them and to make sure there is no leakage in the nearby underground communications.
How to adjust the humidity in the basement? For this, mankind has long invented ventilation. Usually this useful site is envisaged even before the construction of the house. Vents( blowouts), which are available in the basement of almost any building, just play the role of ventilation. If the house is not yet built, then this way of ventilation will be an excellent solution, because it does not require additional costs and fully functions. It is best if the vent holes are covered with metal nets to insure against rodents. In the cold season, the air purge should be tightly closed.
Supply and exhaust ventilation
If the area of the basement room is of considerable size, and the height to the ceiling exceeds 2 meters, then it will be best to provide for the supply and exhaust ventilation. The operation of this ventilation system is based on the difference in temperatures inside and outside the room. In the construction of the building it will be sufficient to provide two air channels.
One end of the exhaust pipe is best located under the ceiling of the basement, and the second on the roof. If the house has a stove or fireplace, it is advisable to provide for the exit of the pipes near. From this, the pulling force of the ventilation increases significantly. The supply pipe can also be put on the roof, but its lower end should be located not more than one meter from the surface of the basement floor. It is recommended to equip the outlet and the inlet of the supply air duct with metal grids and flaps. This will help, if necessary, to regulate heat exchange and air humidity in the basement.
Ventilation in the cellar
If the basement is made under a cellar, then ventilation is necessary, like nothing else. If the humidity of the air in this room is exceeded, then the cellar simply ceases to be effective. Increased moisture is given a favorable environment for the appearance of mold. Keep food in an unventilated room does not make sense. A spacious cellar without fears and doubts can be equipped with supply and exhaust ventilation. The thickness of the pipes should be taken into account in accordance with the size of the room. Most often in the cellars of private houses or cottages you can find ventilation ducts made of PVC with a diameter of 20-60 cm. This is a common, but not the best solution for cellars. If the duct is made of tightly fitted boards, it will be much better. Adjust the amount of air entering the cellar by raising or lowering the supply pipe. Air exchange according to the norms in the cellars: from one to two meters in a cube.
A small cellar can be equipped with a wooden duct with one channel. Such a device will be effective, provided that it will be equipped with a wind trap, and inside the channel will be divided into two parts - supply and exhaust. The system is still the same, it may require you to spend more effort on installation and training, but if you can not install two pipes - this is the best option. For a small basement is also suitable supply and exhaust ventilation.
How to adjust the air exchange with the ventilation system
To check how effectively ventilation works, you can bring the lit match to the exhaust duct. If the match is extinguished, this means that there is a lot of carbon dioxide in the room. Solve this problem by expanding the supply pipe. If its diameter is too low - the incoming air will simply not be "hooked" for anything. Both pipes should be equipped with grids in the upper parts. In addition, it is recommended to install on their lower parts dampers and tightly closed lids, with which you can slightly change the temperature in the basement or cellar.
Ventilation in the basement maintains normal humidity, but with it you can not fully regulate the temperature. To do this, in the cellars or cellars need to provide insulation, which is necessarily useful if the room often will be people.
Ventilation in the basement with your own hands
Basement ventilation example
It is not difficult to make ventilation in the basement yourself. It is enough to have a small master or construction skills and to purchase the necessary materials. PVC pipes are quite common, clamps are also not uncommon. For fasteners bolts and nuts are best suited. In some cases, a drill may be required. On the walls, a light PVC pipe can be held with clamps forever. The main thing is to fasten all the assembly units. If the pipe is metal( ferrous metals), then it is better to use welding and fixings in the wall. A wooden duct can be built from any type of wood. The main thing is to cover the boards with protective means.
Basement Ventilation Scheme
On the exhaust duct, it is necessary to provide a condensate drain cock, since moisture is released through it. Gradually, moisture begins to accumulate on the inner surface of the pipe and drain off. The through hole of the exhaust pipe is best done 20-30 cm from its end. All that will be below, you can call a pallet, at the very bottom of which will be located a small hole. To it it is possible to connect a crane or a pipe which will be connected with the water drain. At the second variant of execution it is not necessary to resort to independent drain of the saved up liquid.
