Perhaps the most popular place in the apartment is the bathroom, but at the same time the most dangerous, because it is in it that the most favorable environment for the appearance and reproduction of mold and bacteria arises. You can warn such processes using ventilation. Reduce humidity, partially remove bacteria and reduce the risk of mold will allow a continuous influx of fresh air. To date, two types of ventilation are natural and artificial.
As a rule, fresh air penetrates the room through the doors, windows, and with the help of ventilation ducts comes out with excess humidity and dust particles. Constant traction is provided due to the difference between external and internal pressure.
So, in the bathroom, natural ventilation copes well with the task when the temperature reaches +12ºC on the street.
In the case of an increase in temperature, traction can become much weaker in ventilation ducts, and in the cold period of time it increases slightly, but at the same time the heat losses increase. Air exchange in the bathroom should reach 50 cubic meters. m. per hour.
It should be remembered that the installation of sealed doors and windows significantly prevents the entering fresh air into the room.
It is necessary to choose such products with such constructive features that would not interfere with the free flow of air.
The advantages of natural ventilation include:
– simplicity in the design;
– speed of installation of ventilation systems in the bathroom;
– saving funds during installation;
– lack of complex mechanisms;
– lack of electric wires;
– reliability;
– inexpensive operation;
– complete absence of noise.
The disadvantages of natural ventilation include:
Bathroom: natural ventilation
– dependence of effectiveness on weather conditions;
– shortly finding the system in optimal mode of operation;
– the possibility of adjustment only on a decrease;
– Great heat loss in the cold period of time (40%);
– lack of traction in the summer period of time.
– the inability to conduct preliminary preparation of the supplied air (heating, cooling, filtration);
– the possibility of dampness.
