Ventilation is natural and mechanical. In the projects of modern multi -storey buildings there is always natural ventilation. Gas exchange in the apartment can also occur through leaks in door or window frames. However, this method of ventilation of the premises is ineffective. Air conditioners are also capable of ventilation. Although it is worth noting that this kind of technique works advantageously with the air that is within the apartment and can only cool or heat it, and also mix it within the room. Not all models are capable of ventilation in the full sense of the word, it is necessary to pay attention to this when choosing an air conditioner or split systems.
But first of all, to ensure the influx of fresh air directed precisely mechanical ventilation. In order to make sure of natural ventilation, bring the lit match to the grille. If the flame of the candle deviates to the side, then fresh air still enters your apartment from the street. However, the efficiency of mechanical ventilation residents of the apartment always felt almost instantly. The stopped pain in the head, constant dry mouth and excessive sneezing — these are the symptoms that leave forever the ventilated room. However, it will be difficult or almost impossible to choose the equipment for the installation of mechanical ventilation to a stranger.
In extreme cases, the room will not ventilate at all or the air under pressure will begin to enter the apartments of your neighbors. Cope with such a task exclusively to professionals who will carry out all the work in such a way that the air is evenly distributed throughout your apartment.
