Ventilation in a private house

As it has been repeatedly mentioned, when designing ventilation, it is important to adhere to the division into “clean” and “dirty” zones. All ventilation equipment is selected depending on the chosen option.

Where do you cook - in the kitchen-living room or in a separate kitchen area? Depending on the answer to this question, exhaust ventilation is installed for houses of different layouts. In the first case, the project includes the division of space into “clean” and “dirty” zones; in the second, the entire room is considered a “dirty” area.

When cooking, odors, smoke, gases, moisture, and heat are emitted. In no other room is such an amount of polluted air emitted with such frequency (except perhaps with a bathroom). The main task is to remove this air from the room, and this requires a powerful kitchen hood.

Kitchen ventilation can be implemented according to two scenarios. The first is a duct system arranged according to the scheme: a check valve, an air duct and in-line duct fan. Alter Air offers duct equipment from Systemair (Sweden), Soler&Palau (Spain), Ostberg (Sweden), Ruck (Germany), Salda (Lithuania). 

​Another option is to install a classic axial or centrifugal fan. Exhaust fans Meltem (Germany), Maico (Germany), Vortice (Italy), Soler&Palau (Spain), Systemair (Sweden), Lessar (Lithuania) perfectly cope with the task. 

​And, finally, the most effective option for the kitchen is the central supply and exhaust ventilation with Jablotron recuperation and variable air flow valves. The kitchen hood without the engine, developed by Jablotron and Faber, not only effectively removes dirty air from the kitchen, but also creates a balanced air exchange.

An exhaust fan is a mandatory piece of equipment for the bathroom and toilet, regardless of the ventilation system you prefer.

We discussed the types of fans above; for the bathroom, it is preferable to install models with a timer and a humidity sensor. Among the brands that our company is ready to recommend are Meltem (Germany), Olimpia Splendid (Italy), Maico (Germany), Soler&Palau (Spain), ELECTROLUX (Sweden), Elicent (Italy), Вентс (Ukraine).

Outerwear, fur, leather, synthetic and natural fabrics are a source of odors. To create normal storage conditions in the dressing rooms, fans of periodic switching on, two-speed or standard, are installed. These can be Meltem (Germany), Olimpia Splendid (Italy), Aerauliqa (Italy), Elicent (Italy), ELECTROLUX (Sweden), Vents (Ukraine), MAICO (Germany), S&P (Spain), Helios (Germany), Vortice (Italy).

​All living areas are a clean zone. In the living room, bedrooms, nursery, study and other spaces with similar functions, a person spends most of the time. It is important to supply fresh air at a comfortable temperature here with the help of supply equipment — breathers (Ballu, Airnanny, Tion), supply valves (Marley, Systemair, Maico), recuperators (Meltem, Olimpia Splendid, Airauliqa, Marley, Blauberg), air handling units (Jablotron Futura, Zehnder, Stiebel Eltron).

A separate ventilation is always created in the garage, and only exhaust.

The design of the garage, unlike a residential building, is leaky because the garage doors have gaps. The temperature here is artificially maintained at +8°C.

When you enter the garage, you turn on the light. At the same time, the fan should turn on, taking the gases that are emitted by the running car. A duct exhaust ventilation system is being created according to the following scheme: a front grille, an adapter, an air duct, a check valve, an exhaust fan, an air duct that is connected to the grilles, which will extract gases.

After leaving the car, the timer continues to run for 30-40 minutes.

Even if the car is in the room and is not used, it produces odors. Therefore, it is important to provide an intermittent exhaust system that regularly removes polluted air.

As for the inflow, fresh air is mixed in due to the leakage of the gate.

Underground facilities continue to appear in modern households. Of course, we're not talking about the cellar where Granny keeps her 35 jars of raspberry jam. In spaces of this type, ventilation is carried out in a displacement way: the air flow enters the lower point, the supply is carried out near the floor, and the top layer of air is extracted.

Basement ventilation, where utility rooms, pantries, billiard rooms, etc., can be located, is based on the fact that the basement is a “dirty” area. It is important to avoid stagnation of air. For this, a centrifugal or axial fan, two-speed or with periodic switching on, is installed. Such constant ventilation of the house is carried out similar to the ventilation in a dressing rooms.

The air supply is provided by any chosen option - a window, a breather, a decentralized ventilation system.

With central ventilation with recuperation, the supply is carried out to the “clean” zone, and the air intake is carried out in the basement. Even at low room temperatures, the air here also has energy that can be returned.

If a central unit with a VAV system is installed in the house, there should be a separate valve in the basement.

​The main thing to remember is that the space is divided into “clean” (living room, bedrooms, study, nursery) and “dirty” (bathrooms, kitchen, dressing room) zones; fresh air is supplied to the “clean” zone, exhaust air is taken from the “dirty” zone.

The desire to independently calculate the ventilation is commendable, but it will take you several weeks, or maybe months of your life (depending on general preparation). The fact is that regulatory documents not only take up entire “tomes”, but also contain many nuances that only engineers know. If you are not ready to delve into the material so deeply, contact the experts, this is a reasonable and balanced decision.

In the section on the cost of ventilation, we provided prices including installation. You can find out more detailed information from our managers by phone 0 800 335 941.

​The frequency of cleaning the ventilation system depends on the mode of operation and is carried out once a year or once every six months.

There are such possibilities, here is one of them.

Often in a house under construction, people lay ventilation ducts in the bathrooms - we have already talked about their dangers. 1 meter of the channel costs at least 1000 UAH. There are at least four such ventilation ducts, each 6 meters high. In total, you risk spending 24,000 UAH on ventilation ducts.

However, there is an alternative - a decentralized system with heat recovery and ducting. You will save 24,000 UAH, increase the efficiency of the building, as you will use the energy that you planned to throw away.

One of the mistakes concerns an already installed system.

It is made by engineers: they choose the wrong diameters of air ducts and diffusers from which air comes out. They make too small a section and reduce the area of ​​​​air ducts.

As a result, the cost of ducting is reduced and the system as a whole also becomes cheaper. Inexperienced customers like this solution and they are willing to buy it. In living rooms, people sew up air ducts with ceilings, furnish the room with expensive furniture and hang lamps - but the ventilation system turns out to be so noisy that it is difficult to stay indoors.

You can't skimp on aerodynamics. You do not save on other laws of physics, say, do not check the work of gravity by jumping from the third floor?

It is not easy to fix the described mistake - it is even easier to change the unit, but getting a long ventilation duct is an order of magnitude more difficult.
