Proper ventilation in the bathroom - the basic provisions and the exhaust fan selection

Proper ventilation in the bathroom

Some utility rooms in the house or apartmenta number of reasons the most exposed to the process of condensation, so in them it is advisable to install additional ventilation devices. Bathroom - one of these facilities, and inadequate ventilation leads to unpleasant odors and an increase in humidity, which in turn, is fraught with condensation settling on the walls, floor and ceiling, which is a breeding ground for fungi and bacteria. Proper ventilation in the bathroom tiles and furniture will keep mold from the raid, will extend the service mirrors will eliminate the causes of odors.

Simple ways to ventilation

Simple ventilation in the bathroom byventilation or with the help of passive exhaust ventilation system may not be fully effective. In multi-story houses built over twenty years ago, the ventilation system is gradually polluted and no longer cope with the increasing workload.

The appearance of mold on the tile surface

The appearance of mold on the surface of the tiles in the bathroom shows insufficient ventilation

To avoid such troubles, and musty smellmold on the walls will help mechanical ventilation in the bathroom, which will remove the moist air out of the bathroom into a common duct and prevent it from returning to the premises.

Poor ventilation in the bathroom is correctedin several ways. First, the most simple, does not require any material and physical costs - this is an open door, which promotes a constant change of air in the room. This method is justified in cases where the aesthetic component of the dwelling is not decisive. Simply put, if the owners do not care that the bathroom is exposed for everyone to see, this method - perfect. The second method is suitable for those who are already aware of a problem, but not yet ready for its radical solution lies in expanding the gap under the door. The increase in the door gap of only 2 cm is quite capable to solve the problem of ventilation of a small bathroom.

Selection and calculation of the exhaust fan power

The most effective way - settingVentilation in the bathroom in the form of a compact electric fan, which will cope with the task, even if there was only a small gap in the years unpeeled general ventilation system. For this purpose, generally used wall axial fans. When choosing such a device in the first place should pay attention to:

  • Safety, as the fan - electric appliance, and the bathroom - a room with high humidity, therefore, protection against ingress of water or steam should be the maximum.
  • The level of fan noise, which can irritate the tenants of the apartment. You can set the attenuator, and if that is not enough, then install sound insulation materials inside the duct;
  • The power stretcher must be optimally correlated with the size of the bathroom, and the number of users. If fan power is not enough, install it loses all meaning.

Important! Before you make the ventilation in the bathroom, you need to determine the fan capacity. Calculate the required fan power by the formula 6V or 8V, where V - volume of the bathroom and 6 and 8 - coefficients corresponding to the number of people who are constantly using bathroom. Factor 8 is used in the calculations, if a bath uses more than 3 people.

Ventilation in the bathroom and the toilet can beconnected to a light switch, and in this case it will work only when it is really necessary. However, not all are delighted when staying in the toilet or bathroom is noisy ventilation. In this situation the best thing to do for the self-hood switch and use it when its work will not interfere with anyone.

The main ventilation installation rules

And passive and forced exhaust ventilation in the bathroom should be located:

  • For the greatest possible height, preferably directly under the ceiling;
  • How far away from the fresh air source (ideally - on the opposite side), otherwise it will be ensured only local ventilation practically does not affect other parts of the bathroom;
  • The fan should be installed away from water sources to avoid short circuits.
Improperly installed ventilation

Improperly installed ventilation - most of the air mass remains outside the zone ventilation and air coming through the door, immediately goes to vent

Typically, installation of ventilation in the bathroom is notassociated with additional difficulties, but on the fan setting is better to think in advance. In this case, it is possible to hide the wires inside the walls during the renovation work. If the work has already been completed, and the hood has not been established, all the time until the next bathroom renovation will "decorate" the wiring leading to the fan.

And what about the ventilation in a wooden house?

Ventilation in a private home in the bathroom should beinitially included in the project: usually in the bathroom, toilet and kitchen are located hidden ventilation shaft, complete with decorative grilles at the entrance. If the bathroom is located in a private house on the first floor, you can do normal ventilation using natural convection. However, more often in private homes doing multiple bathrooms, so in the bathroom on the forced ventilation must be installed last floor of a private house.

bath in a wooden house

From a wooden house is humid and warm air has to be removed as quickly as possible, until he had a negative impact on tree

Ventilation in the bathroom in a wooden house experienceserious additional burden due to the nature of the material, so it imposed very different requirements. The same applies to the bathrooms, which are fitted with wooden furniture. And the wooden walls and furniture and interior items are very much exposed to high humidity, so the design of the bathroom in a private wooden house more ventilation ducts and installed exhaust ventilation should be provided. It is not recommended to use for these purposes conditioners, since they strongly dried air, and constant humidity fluctuations can lead to cracking of wood.
