it is high time to start designing and installing it yourself. Such work is quite simple. In apartment buildings, the systems are design so that the ventilation ducts are locat on the back side of the baths and toilets. The entire procure will consist of carefully creating a hole and leading it into the ventilation duct. In multi-story buildings, there should already be niches leading to the ventilation ducts.
The niches themselves are usually equipp with radial, axial fans; the devices are connect to power sources, one of the wires is connect either to a separate switch or to the same dentist data that opens the light circuit in the bathroom. This is quite convenient, since the fan will be guarante to work when the light in the bathroom comes on.
The range of modern systems on the market of ventilation
the installation of many additional hanging devices – gyroscopes, temperature sensors, humidity controllers, spe controllers, timers. After that, the opening is clos with beautiful decorative grilles.
In cases where the bathroom is not combin, when the what can you sell on recommendations for different audiences contains a ventilation duct, but the toilet does not, the same technology is us, only twice. The first fan is install in a niche between the bathroom and the duct, the second – in the second niche, between the toilet and the bathroom.
In the case when it is necessary to install ventilation in the toilet in a private house, you can make not only the outlet to the ventilation duct, but also the ventilation duct itself with your own hands. Experts advise either to take the ducts into account when erecting walls, or to correctly connect to the exhaust system of the stove (if there is one).
Let’s move on to practical diagrams and projects of ventilation systems.
System design
For the installation of fans in wall openings, the most correct italy numbers is to use not only decorative grilles, but also filtration systems. If you have to knock out an additional hole between the bathroom and the toilet (for air supply), then a filter between the two rooms is a very rational fragment of the ventilation system. After all, pollut air from the toilet will not be able to penetrate into the bathroom.
Recommendations from experts
- Experts advise not to put off inspection of the ventilation system all the time; it is highly desirable to service the fans a little earlier than they start to fail.
- As a rule, if inspection is constantly postpon, then flakes of dust, cobwebs or poplar fluff get into the fan axis, block the rotor and stator motor for a long time, after which the fan simply fails.
- Of course, buying a new motor or a whole fan is a simple solution to this problem, but you will still have to clean the ventilation duct. It is much easier to do this work on time.
- Do-it-yourself fan maintenance includes cleaning the fan blades, thoroughly cleaning the ventilation grilles, and replacing all filters (if any).
- After this, it is necessary to check the air draft using a sheet of paper or a lighter flame (we describ above how this procure is perform). If the flame from the lighter (or match) deviates at an angle of 40-50 degrees, then the fan operation is consider normal; if the flame does not deviate, then the ventilation duct is consider clogg and further operation of the fan is a load.
Ventilation in the toilet and bathroom: how to do it yourself?
The bathroom and toilet, where unpleasant odors and condensation accumulate, most of all ne an exhaust system. A high-quality exhaust system ensures a normal microclimate in the premises that meets sanitary and hygienic requirements. To organize an exhaust system, you ne to study the rules for installing a fan.
What is the purpose of a hood?
The ventilation system in the bathroom is a finely organiz structure that affects the microclimate of the room. Mold that appears in the bathroom indicates a malfunction of the ventilation system or the insufficiency of the existing one, errors during self-installation or miscalculations during design. Steam rising from hot water creates condensation, which accumulates on the walls and eventually turns into fungus. Cosmetic repairs will temporarily get rid of stains, so the problem is solv at the root. It is necessary to make an effective ventilation system and ensure air exchange, since the organization of a healthy microclimate for a person during bathing and other procures is impossible without this. According to SNiP and other regulatory documents, to create forc air exchange in rooms with high humidity, ensure the supply of fresh air, adhering to the following indicators:
- 6–8 m3/hour per 1 cubic meter of area for a bathroom;
- 8–10 m3/hour – for a combin bathroom.
The exhaust air from the bathroom and toilet is more than 30 cubic meters per hour. For the arrangement of toilets in apartments and private houses, low-noise household fans with a noise level of no more than 30 dB are us.
Calculation of equipment performance
Before purchasing equipment for installing forc ventilation in a toilet or bathroom, make calculations. Knowing the exact volume and purpose of the rooms, select the equipment that is optimal in terms of productivity (read more about how to calculate everything and install forc ventilation here). Each room has its own air aeration rate. The value indicates how many times the air flow will be refresh in one hour. Attention! A bathroom with a toilet is consider a room with high humidity levels; the maximum permissible aeration rate is equal to 10. To calculate the productivity and efficiency of the hood, calculate the volume of the room by multiplying the height by the area. The resulting value is multipli by the air exchange rate. The result, indicat in m3/h, indicates the minimum hood capacity for the bathroom. For example, for a bathroom with an area of 9 square meters and a wall height of 2.5 meters.
