Features ventilation wet rooms

Modern house is unthinkable without an efficient ventilation system.

After all, air quality and the air exchange rate depends on the state of health of man and the comfort level in your home or apartment.

from the article "The system of ventilation of a private house in the questions and answers" readership FORUMHOUSE They can learn about the basic nuances that need to be taken into account when designing the ventilation system in the cottage.

We continue this theme and talk about the features of ventilation wet rooms.

From our material you will learn:

• What is the ventilation in wet areas?
• What will happen if we neglect the ventilation system in wet areas?
• What is natural and forced ventilation system?
• What are the features of the installation of ventilation in wet areas?

Why do we need a ventilation system in a wet basement?

Before turning to the features of the ventilation device in wet areas, it is necessary to understand, what do I need ventilation in the house. Consider the following example: the average adult spends in the house from 10 to 15 hours a day. During this time, he breathes in up to 20 thousand. liters of air. If the room has no permanent ventilation and fresh air, it will negatively affect the well-being of all family members.

Sergey Chulkov (Engineer company VentMaks):

- Ventilation is required to create a comfortable microclimate in the house.

Indoor climate depends on the following parameters:

• air temperature;
• humidity;
• air velocity;
• Temperature walling;
• degree of concentration of harmful substances (e.g., carbon dioxide).

By Russian standards, the entire volume of air in the house must be completely updated 1 hour.

Boris Butz (The head of the technical department of the company "AERECO"):

– The main task of the ventilation - maintaining cleanliness of air in a closed room by simultaneous influx of external and cleaner removal outwardly over the inner dirty.

In wet areas - pool, conservatory, laundry room, sauna, etc. at washing bath or visit reception steam produced excessive amounts of water vapor.

These pairs further increases the concentration of moisture contained in the air circulating through the house.

If it does not take time, it is possible to encounter some unpleasant phenomena, such as high humidity, dampness, mold and dampness of the interior elements, especially in wet areas.

Because water vapor tend to gradually accumulate in objects and Walling, the excess moisture eventually leads to the destruction of building structures. In addition, the humidity in the house of a negative impact on the health of people.

Constant dampness caused by a lack of ventilation, promotes the growth of various bacteria, which can lead to the spread of disease in the house.

Solve the problem of excessive moisture in the "wet" premises of the device helps the ventilation system, which:

• prevents condensation;
• It keeps the relative humidity of the air in the normal range;
• prevents the occurrence of drafts in the field of human presence.

Sergey Chulkov:

- When calculating wet areas of the ventilation system should create a negative imbalance, in which the exhaust flow will prevail over the influx.

This prevents overflow of odors in the living room. For operation of the exhaust system is necessary to provide air flow from adjacent spaces. To do this, provided the gap under the doors of toilets or transfer grille. In this case the air velocity should not exceed 0.3 m / s, to avoid unpleasant drafts in humans, visiting the lavatory.

If the house is built a swimming pool, the ventilation system must be designed so that the air jets are not fell directly on the surface of the water, because This can increase the rate of water evaporation and increase in humidity room.

Features of the ventilation system in damp rooms

The efficiency of the ventilation in wet areas is largely dependent on how organized air exchange in the house. To do this, you need to decide on the method of ventilation and choose the appropriate equipment.

Boris Butz:

- the ventilation system comprises two binding parts - a device providing external air inflow and removing dirty.

All ventilation equipment is selected based on the performance operating noise, power consumption, etc. - in accordance with the characteristics of the premises and in accordance with regulations.

Think through the ventilation system should be more at home on the design stage. If this is not done, then, during installation of the ventilation system have to remodel and rebuild ready and decorated rooms, which will lead to additional costs.

Sergey Chulkov:

- When placing the wet rooms on different floors of the house, in order to simplify design ventilation, it is best to group them in the vicinity of the central exhaust ventilation shaft. And in case of reconstruction and remodeling space should not be moved already built toilets.

In addition, you must choose the way of ventilation.

Ventilation can be:

1. Forced - air exchange takes place through the use of mechanical equipment, such as fans. The house is equipped with ventilation with mechanical drive, the fresh air coming from the ventilation unit. Conditioned air passes through the filtration system and heated to a comfortable temperature, and its removal takes place by means of exhaust fans.

2. Natural - air exchange takes place without the use of mechanical equipment. Movement is caused by the difference of airflow temperature and air pressure inside and outside it. The house is equipped with a ventilation system with a natural impulse, supply air flow going through the adjustable opening elements: windows, vents, skylights, slots or built into the exterior walls valves. A venting occurs through the vertical ventilation channels with access to the roof.

Both methods have their pros and cons.

Sergey Chulkov:

- The disadvantages of natural ventilation wet areas include the fact that it is difficult to reconcile with modern energy-saving requirements.

Modern standards air permeability of windows and doors provide enhanced integrity, but significantly deteriorates airflow. A calculated for natural ventilation is open vent mode when the outside air temperature + 5 ° C and windless weather. If the ambient temperature increases the thrust, while in hot weather, wind effects can only provide the desired breathability.

Natural ventilation occurs because of a pressure drop on the inlet and outlet of the ventilation system. Login - this exhaust valve. Yield - is the height of the ventilation pipe. influenced by the temperature difference between the air inside and outside the room as the efficiency of the natural ventilation.

Winter natural ventilation efficiency is increased.

In addition, in the system of natural ventilation possible the phenomenon of "tipping thrust" when, instead of removing the dirty air outside, everything is exactly the opposite: outside air enters the bathroom and dirty - spreads on related premises. In addition, the limitation of the performance of the natural ventilation and impose building height. For example, in a two-story house tractive force at the natural system on the ground floor is higher than the second.

Sergey Chulkov:

- If you go back to the issue of energy saving, the most effective operation of ventilation with variable air volume flow by means of fans.

In addition, modern, properly designed and installed the ventilation system may be one of the key elements of an energy-efficient home. To this end, the ventilation system fitted with air heat exchanger, which reduces energy losses and reduced heating costs.

editing features and the ventilation devices in wet rooms

Proper selection and installation of equipment - the key to successful operation of the ventilation system. Mechanical ventilation wet rooms System includes the following equipment:

• fan;
• duct system;
• check valves;
• Diffusers (lattice) installed indoors;
• adjusting devices (throttle valve).

- The installation of the ventilation system in a damp location is necessary to maintain the distance between the air intake grilles ventilation grilles and exhaust-ventilation system.

You should also foresee inspection hatches for future maintenance of the system.

Ducts must be securely fastened.

Installation duct is conducted without deflections, in which subsequently can accumulate moisture. The entire length of the duct all joints and connections are well compacted.

Careless Angel (Member FORUMHOUSE):

- Keep in mind that you can not combine the air duct in the kitchen with a bathroom and air duct ventilation system to the sewer standpipe. Otherwise, spread odors throughout the home.

Therefore, air ducts for lavatories and bathrooms should be designed separate from other rooms: kitchens, saunas, baths, boiler rooms and garages.

Basic requirements for air wet areas: while in a wet state, with time they should not lose strength, integrity and tightness and resistance to be different Corrosion. Ducts should not have holes, except those required for the normal operation and maintenance.

Blackbird(Member FORUMHOUSE):

- In my opinion, the best option of the duct - a spiral-wound galvanized ducts.

Among its advantages are:

• light weight;
• simple and convenient installation;
• low price;
• many additional elements.

But the corrugated duct is better to use only when splicing in difficult and uncomfortable places, sinking bends, etc., since the corrugation is very noisy, it has a greater resistance to air flow and collects much dust and dirt.

Boris Butz:

- The layout of ventilation ducts on the premises is carried out in strict accordance with the design of the ventilation system.

Besides it is necessary to choose high-quality fans. Fans are:

• wall and duct;
• plastic and steel;
• on / off operating on the principle;
• running timer or humidity sensors or movement.

Fan is selected for a particular ventilation system using aerodynamic calculation and with account of technological features and requirements for the noise.

Sergey Chulkov:

- Install the fan should be carried out, ensuring regulatory noise levels in residential areas.

If you can not place the fan in a location where it will not cause noise interference, it should provide for the installation flexible inserts, silencers, install a fan in shumozaschischonny body or use soundproof ducts. When the fan selection is necessary to pay attention not only to the air flow rate and power consumption, but also on he creates air pressure (static pressure of the stream), from which the system performance depends ventilation.
