What can be cooked from squid: quick and tasty

Has the apartment become too stuffy, the windows have begun to fog up, and the characteristic kitchen and toilet smells remain in the premises for a long time? The reason for all the troubles is the same - insufficiently effective ventilation.

This problem requires an early solution. Otherwise, you run the risk of saying goodbye to wallpaper, furniture and other items of arrangement of the apartment, which will simply begin to rot in conditions of excessive humidity.

You can equip an efficient and reliable ventilation system in an apartment on their own... It is absolutely not necessary to have any specialized skills to perform such work - you just need to have basic knowledge of carrying out the relevant activities and be able to work with elementary construction tools.

Read the presented manual, do everything in accordance with the recommendations given, and you will forever forget about the problems that arise in the conditions of insufficient ventilation of the apartment.

Ventilation requirements in the apartment

In accordance with the current sanitary standards such ventilation is considered sufficient when in each room the exhaust air is completely replaced with fresh air at least twice an hour.

Initially, ventilation is supplied to each apartment from a common ventilation duct. However, in some situations, the power of such a system is not enough to provide the required level of air exchange.

Exhaust fan assembly

To ensure maximum efficiency and performance of the ventilation system, install modern exhaust fans in the bathroom and kitchen. Today, a large selection of such devices with various characteristics is available in specialized stores.

To determine the appropriate power of the exhaust fan, you need to multiply the volume of the room by 7 for the bathroom, for the kitchen, multiply by 10.

For installation in it is best to purchase a unit equipped with a humidity sensor. Such a device will automatically start when the humidity level rises above the permissible value.

Suitable for a toilet exhaust fan with a preset timer. Thanks to the timer, the unit will automatically turn off some time after starting.

For kitchen installations, try to find a fan model with a mesh. Thanks to the grid, the possibility of all kinds of insects and debris entering the room will be excluded. Such nets are easily removed and washed with ordinary water.

If you could not find the exhaust fans described above on sale, or if you cannot buy them due to the lack of sufficient Money, get a regular model. In the bathroom, it is recommended to connect the fan directly to the switch - as a result, the hood will start up when the light is turned on.

The installation of the unit is carried out in accordance with the instructions, there is nothing complicated about it. Usually, it is enough to simply attach the body and related parts to the wall using self-tapping screws. In general, follow the manufacturer's recommendations for your chosen fan model.

To further increase the efficiency of air exchange, it is recommended to create 1-1.5 cm gaps between the floor and the lower edges. interior doors... Such gaps are needed everywhere, with the exception of bathrooms. To mask the gap, you can install a special decorative perforated panel or mesh.

You now have the information you need to self-arrangement simple . Follow the recommendations received, and you will forever forget about the problems associated with ineffective air exchange.

Happy work!

Video - Do-it-yourself ventilation in the apartment

Many homeowners associate ventilation systems with exhaust grilles and vertical shafts that run through the roof. It is true that these elements are engaged in the removal of exhaust air, but without an external inflow, the hood works ineffectively. For full air exchange, supply ventilation is needed to compensate for the outgoing air masses. The problem is solved in several ways, discussed below.

Inflow options

Let us explain the importance of supply ventilation using an example. Imagine a sealed container of water being pumped out by a pump. Since the vacated volume is not filled with air, the pressure in the reservoir drops. At a certain moment, the pump will not have enough power to overcome the vacuum and further pump out - the impeller will begin to stir the water in place.

Key moment. When air exchange inside the premises, a similar principle applies - natural or forced exhaust will not be able to effectively remove polluted air, if replacement with an inflow is not provided.

After installing sealed plastic windows and laying the supply slot, previously located under the windowsill, the flow of air masses from the outside is excluded. Consequences: a fan or ventilation duct of a larger section (usually in the kitchen) overturns the draft in a smaller shaft (toilet), from where an unpleasant odor enters the apartment. The living room, bedroom and other rooms remain completely without ventilation.

There are several ways how to make a full supply and exhaust ventilation of a private home:

• folk method - trimming window seals;
• buy an air conditioner with the function of supplying street air;
• build an adjustable air valve into the plastic window;
• make a hole in the wall and install a local air inlet.

Advice. The performance of a natural home hood can be checked as follows: remove the ventilation grilles in the kitchen and bathroom, attach 2-3 strips of paper over the first opening, close the second tightly with A4 sheet and tape. If the strips are drawn into the channel, it means that air is entering the apartment - the draft is working.

Let's take a look at the pros and cons of each of these methods. The task is to offer you the correct and relatively inexpensive way organization of inflow.

Simplest free method

The essence of the method lies in the use of existing drainage holes in the window profile, designed to drain condensate outside. Two hidden holes where water goes out are located on the inside of the frame, the outlet is on the outside of the profile and closed with plugs, as shown in the photo.

One condition: the method will not work with poor vertical thrust. Start by checking the hood and.

The notion of home craftsmen allows you to quickly organize supply ventilation with your own hands without financial costs:

The operation of this ventilation is built according to the following scheme: under the influence of the draft of the ventilation duct, outside air is sucked in through the drainage hole, passes inside the profile and enters the gap between the sash and the frame. Having risen to the top, the air flow enters the room through the opening in the seal.

In winter, the heating of the cold inflow begins in the window structure and ends at the outlet when the air mixes with the ascending convective flow coming from. The supply slot is made in the same way in the plastic balcony door, but with an additional trimming of the outer elastic, as shown in the video:

The advantage of this option is zero cost and a real opportunity to arrange airing of the apartment with the window closed. There are many more disadvantages:

• the air flow cannot be regulated, a strong wind will blow through the slot;
• in summer, unfriendly insects, such as wasps, can settle in an open drain;
• during a warm period, when the natural draft decreases due to a small temperature difference, the small holes will not allow the required amount of air to pass through.

The last disadvantage: the removal of part of the rubber seal is available only on opening sashes. Drilling blind windows is not an option. Therefore, the method cannot be called correct and cannot be recommended to all homeowners.

Split systems with ventilation function

In addition to heating / cooling modes, household air conditioners from a number of manufacturers are able to supply street air to the room and even work as an exhaust hood (alternately with the supply). Why this option is convenient:

• the air environment in the room is renewed forcibly, regardless of the thrust force in the mine;
• the air drawn in by the fan is processed - filtered and heated or cooled;
• the flow rate is adjustable;
• inflow volume does not depend on wind gusts and other weather conditions.

Reference. The air mixture is sucked in by a separate fan located in the indoor unit split systems. An additional tube is laid through the outer wall - an air duct up to 1 m long.

The main problem with the implementation of such air exchange is high price equipment. Buy an air conditioner for each room for 500-600 USD That is, for the sake of forced ventilation - it is impractical, there are cheaper options. But if you plan to install a split system for cooling, you should think about choosing a unit with air supply and recirculation.

The negative sides of using the air conditioner as supply unit we have formed according to the reviews of buyers of online stores and forum visitors:

1. The inflow is carried out only when the unit is turned on, the rest of the time the outer channel is covered with a damper.
2. A separate fan, responsible for supplying fresh air mixture, is constantly noisy.
3. Due to the rapid contamination, the filters will need to be cleaned more often.
4. On some models, the ventilation and air conditioning modes are not compatible. Air supply and heating are switched on separately.

Note. Correct installation of a split system in a private house or apartment will help you.

Installing the supply valve in the window

The so-called window ventilator is an oblong plastic cover equipped with an adjustment flap. There are 2 types of valves:

1. Mounted on fixed windows. A through inlet slot is milled in the profile, a protective visor is screwed on the outside, and a cover with a flow regulator is screwed on the inside.
2. Products for opening sashes. Installed on the inside of the frame, part of the sealing rubber is replaced with a special material. It is not required to mill the window.

Reference. The valves allow you to adjust the work and are designed for all types of translucent structures - PVC, aluminum and wood. Popular brands are Vents, Air-Box and Aereco, the price is up to 10 USD. e.

It is advisable to use supply window devices in rooms with a good exhaust hood, otherwise the air flow will turn out to be scanty. The declared capacity of the valves is about 30 m³ / h, which is enough for one person, but not enough for normal ventilation of living rooms.

For the boiler room and bathroom, where the norms provide for a more intensive air exchange, 3-4 similar products will be needed, it is easier to embed the transfer grille into the door. Another nuance: the real performance of the devices is very different from the declared one downwards.

It is not difficult to calculate the inflow - find out the dimensions of the inlet slot and determine the amount of air passing through it, using the instructions. The result will be less than the promised 30 m³ / h (let us tell you: no more than 25 cubic meters at a speed of 1 m / s). For 3 family members, you will need 4 valves in each room, absurd.

How to install a supply valve on a leaf:

It is more difficult to install the valve in a blind frame - you need to carefully cut out a narrow opening in the profile. If you do not want to contact the masters and pay money, make the gap yourself - apply precise markings and drill holes. The visor and the inner cover can be installed without problems. Brief instructions for installing the product on the sash are presented in the video:

In general, window ventilators are suitable for a small apartment. But in the rooms of a country cottage with high ceilings, the declared performance is not enough. The second negative point: often the PVC window frame is half closed by the upper slope, there is no room for the valve. Then another is realized technical solution entitled…

Wall ventilation device

The wall-mounted passive ventilation valve consists of the following elements:

• supply pipe with a diameter of 60-150 mm (size depends on the model and performance of the device);
• the outer end of the pipe is closed mosquito net and ventilation grill;
• an adjustment damper is built in at the other end;
• from the side of the room, the pipe is connected to the body where the air filter(cleaning class G3) and thermal insulation pad.

Note. To prevent condensation from forming inside the channel, a layer of insulation is laid between the wall and the pipe.

As in the previous case, the inflow through the valve is provided due to the vacuum created by the exhaust shafts or fans. The products are capable of passing 35-60 m³ / h of air into the room, depending on the user setting. When a local hood with mechanical impulse is turned on, for example, a kitchen hood, the inflow flow rate will also increase to 70-90 m³ / h.

In devices of various brands, there are 2 types of performance regulators - petal and diaphragm, the second will cost less. Any damper can be completely closed if required. The price of products starts from 15 USD. That is, popular manufacturers - Vents, Domovent, Helios and others.

How the valve is installed:

1. Determine the location of the ventilation element. The recommendation is as follows: devices of low performance with a Ø60 mm pipe are best placed between the window sill and the radiator. Place valves with a diameter of more than 10 cm next to the window opening at a height of 2 m from the floor.
   
2. Make a hole in the wall using a hammer drill and a set of drills of the appropriate length. In wireframe either wooden house use crown drills. If the room borders on a balcony, it is better to drill from the outside.
   
3. Cut the pipe to the thickness of the fence, wrap it with Penofol insulation and insert it tightly into the hole. Blow out the remaining cracks with polyurethane foam.
4. From the inside, attach the valve body to the wall by connecting to the pipe. Place a ventilation grill outside.
   

Advice. Make the hole as round as possible, be guided by the outer diameter of the channel wrapped in insulation. Vents products are equipped with telescopic sliding pipes, they do not have to be cut. See the video for installation details:

The scope of application of passive inflow devices is much wider than ventilation in an apartment or country cottage... The valves can provide air exchange in other ancillary buildings - a bathhouse, a boiler room,.

There are only two disadvantages: the lack of heating of cold air and manual adjustment during operation. In summer, the damper opens completely, in winter it is set to a minimum. Advantages:

• the valve is suitable for most ordinary users in terms of price and performance;
• incoming air is cleaned by a filter;
• the device does not freeze and does not become covered with condensation, frost appears on the head when the frost is below minus 35 ° С;
• does not consume electricity, operating costs are minimal.

Breathers and recuperators

The problem with the supply of cold air, typical for wall valves, is solved in breathers - local supply units equipped with a fan and an electric heating element. Unit advantages:

• three stages of inflow purification - in a coarse, fine and sorption (charcoal) filter;
• heating the air to the set temperature;
• automatic and manual fan performance control;
• air quality monitoring - measuring humidity, temperature and carbon dioxide concentration;
• partial recirculation - return of room air after filtration - saves energy;
• remote control from a remote control or a smartphone.

We note 3 disadvantages of the unit: operating costs for electricity, high cost of the breather and its repair in case of failure. There is no point in describing the installation technology - a household appliance is built into the wall similarly to a valve.

Reference. With the help of breathers, it is convenient and comfortable to ventilate any living space. But it is difficult to call the units publicly available - the price of products of the well-known brand "Tion" starts at $ 300. e.

A wall recuperator, an air handling unit capable of taking away the heat of the exhaust air, will cost even more. There are 3 types of installations, differing in cost and principle of operation:

1. Reversible (sellers call them regenerative). The algorithm of operation is simple: first, the exhaust air heats up the ceramic heat accumulator, then the only fan changes the direction of flow and the element transfers the accumulated heat to the inflow. The cycle is repeated at intervals of about 1 minute.
2. Rotary. There are 2 fans constantly running - supply and exhaust. Both streams pass through a rotating rotary recuperator exchanging heat.
3. Cross-flow. The extract air transfers heat to the supply air through the thin walls of the aluminum or copper heat exchanger. The fans direct the flows towards each other, as shown in the diagram.

Most effective option recuperation - in a cross-type heat exchanger, which allows to return about 70% of thermal energy back to the room. The efficiency of the rotary unit is slightly less - by about 5%. The real heat transfer rates in reversible units are unknown, and sellers, as usual, overestimate the efficiency of these recuperators.

Conclusion

So, full-fledged supply ventilation in apartments and private houses can be organized using valves and forced ventilation units. Recuperators and breathers are quite efficient, but expensive, window valves supply little air. A compromise solution is a natural ventilation supply unit installed in the wall of the apartment.

With the onset of winter, most apartment owners, in typical high-rise buildings, are faced with the problem of proper ventilation of the room. System central heating, which is the main source of heat, often cause severe dryness of the air. As a result, the very favorable microclimate that should contribute to comfort is not created. What should be the ventilation of the apartment in winter and how to do it correctly so that the well-being of each family member is always excellent.

Winter ventilation

Often, in winter, plastic windows interfere with the very necessary air flow into the room, which is necessary for proper circulation. To put it simply, the air from the street must flow in exactly the same volume as it is removed from the apartment through the exhaust openings of the kitchen and bathroom. In the summer, even with installed plastic double-glazed windows, this is easily achieved by ventilation through open windows. But in winter, you see, at minus 20 degrees. few people will open their windows wide open for fresh air.

Thus, a clear problem looms, especially in apartments with plastic windows:

• ventilation is necessary even in winter period time in any apartment;
• efficiency and constant air circulation in the room will depend on air exchange: on volumes supply air and air volumes at the exit from the premises;
• care must be taken to create such ventilation that does not necessitate opening windows or vents to allow the required amount of fresh air to enter the room.

That is, it turns out that initially it should be done so that the supply ventilation in the apartment in winter corresponds to high rates.

In multi-storey residential buildings, especially those erected in Soviet times, all room ventilation is reduced to the so-called natural air circulation. Exhaust air outflows into the hoods located in the toilet, bathroom and kitchen, and the direct inflow of fresh outside air is carried out due to cracks in windows, doors or open vents. It is possible not to talk about normal ventilation in this way, especially when double-glazed windows are installed, and the natural ventilation arranged in the apartment simply cannot provide the desired effect.

How to improve the ventilation efficiency of an apartment

In order for the ventilation of the air in the apartment to work effectively in winter, you can strengthen it using several methods.

1. Constantly ventilate manually, that is, open the vents for a certain period of time, providing the necessary air flow. The ideal option is to ventilate for 20 minutes, every 3 hours. But given the fact that there is work and other things to do, it is sometimes impossible to adhere to this scheme.
2. Then you should consider the issue of ventilation using special automatic devices. They are installed on windows or vents and open and close them, following the set settings. Such devices are called automatic ventilation systems.
3. For the necessary air circulation in the room, you can use a system in which fresh air is constantly supplied. This is done using special supply valves, which are usually built into the wall. It is mainly installed near a heating radiator. A grille is installed outside, and a valve is mounted on the inside. Sometimes it is equipped with a noise suppressor and a filter.
4. Using a mechanical device to force fresh air into the room. Such a device is a supply valve with a fan mounted in it.

Naturally, for every apartment owner, sooner or later the question arises of how to make ventilation in the apartment in winter or improve the existing one using modern technologies and devices.

Ordinary wooden windows

If you have not yet had time to install new double-glazed windows, then it is best to insulate old windows for the period of cold weather using such material as foam rubber. Today, a special adhesive-based material is sold. Plus, it's also breathable.

Considering the looseness of the insulating material and its porosity, there will be no drafts in the room even with a strong wind. If we turn to physics, it turns out that the air, passing through the structure of the foam rubber, even heats up a little, since air friction occurs. The so-called throttle effect.

Plastic windows

These models do not require insulation at all, since when correct installation they completely exclude the presence of any gaps or non-densities. In almost all modern types of windows, instead of the vents, there are special slots, the size of which can be adjusted. They allow you to bring the required amount of fresh air into the apartment.

At their expense, ventilation is provided in the apartment in frost. This inflow slot is arranged so that the cold air coming from the street is directed downward and, mixing with warm air from the heating radiator, it is distributed evenly.

Inlet valves

Supply- exhaust ventilation in an apartment in winter is impossible without these devices. They must be installed in the kitchen without fail. There are two types of these devices. Some have a straight, rigid structure. Others are corner devices having a flexible hose. But all of them without fail have built-in dampers that allow you to regulate the incoming air flow. Some models have a built-in heater.

Angle valves are the least efficient and cost effective. They are installed mainly above the batteries, laying a flexible duct hose with a downward slope. This is done in order to exclude the ingress of moisture from precipitation and dust.

Straight type valves have high working efficiency. In addition to the inflow, they also provide purification of the incoming air due to built-in filters. Minus one: unlike angle valves. These models have a complex structure that is very visible from the outside of the building.

To provide high level air circulation throughout the apartment, supply valves need to be installed in each room.

Additional hood

It also happens that the installation of supply valves still does not cope with the required task. In such cases, the exhaust ventilation in the apartment in winter is additionally equipped with mechanical fans. They are installed in vents, thereby increasing the air circulation in the room. True, there are several factors to consider here.

Installing a conventional fan into a bathroom vent will not work. For such a room, you need to choose a device that has a certain degree of protection against the humid environment of the room and the electric motor is in a protective case. ideally, it is advisable to purchase a model with a humidity sensor installed on it.

Devices with saber blades have the lowest noise level. But such models consume a lot of electricity.

In order for the ventilation system of the apartment to work effectively in winter, be sure to calculate the fan power. To do this, you need to know the volume of the room (kitchen, bathroom) and the established coefficient. The values ​​of this indicator are 10 for the kitchen rooms, and 7. The power of the fan model should be 10 times higher than the value obtained for the kitchen, and 7 times for the bathroom.

In custody

The use of these devices allows you to inexpensively and with your own hands make a system in which the room will be provided with the required volume of fresh air. The ventilation system in the apartment in winter allows you to create that very favorable microclimate in the room, which has a beneficial effect on the health of any person.

Device proper ventilation eliminates the formation of excessive dryness of the air. It is this fact that causes a lack of oxygen and poor health in every person.

These methods are the most inexpensive, but effective. A more expensive option is to install split air conditioning systems, which provide not only the necessary air circulation in winter, but also in summer, while contributing to its cooling.

Modern apartments are equipped metal-plastic windows instead of wooden ones, which impairs air exchange in the house. Natural ventilation can be established by airing or installing supply and exhaust mechanisms.

Installation of plastic windows significantly impairs the quality of air exchange. However, a way out can be found

What is the ventilation system for in an apartment with plastic windows installed?

Plastic windows disrupt not only heat exchange in an apartment, but also contribute to the accumulation of carbon dioxide and moisture. They are made according to the technology of complete tightness, so heat does not leave the apartment, but moisture does not leave either. Therefore, forced ventilation in an apartment with plastic windows is simply salvation for all family members and home.

Ventilation for an apartment is divided into several types:

1. Natural. It is carried out by ventilating plastic windows in various modes or using ventilation shafts installed in the functional rooms of the apartment.
2. Forced. It is provided by installing various devices on plastic windows or installing systems in an apartment.

It is important to correctly install ventilation and not be mistaken with its choice, having studied the specialized literature for this.

Natural ventilation

Correct air exchange in the apartment allows you to remove excess moisture and exhaust air, and with them the spores of fungi and mold. Natural ventilation copes with this task only with through ventilation, but it cannot be used during the cold season.

But not all of us care about ventilation and check it regularly, although ventilation shafts in apartments often work poorly, since they are clogged with construction or street debris. Not everyone knows how to check the ventilation in an apartment on their own.

You can check the efficiency of ventilation in the channels with a piece of paper. If the sheet is attracted, then ventilation works well. If he does not move, then there is no sense in such ventilation, you will have to call the master to check the performance and clean the channels.

Using a sheet of paper, you can check the efficiency of the ventilation

In order for natural ventilation in an apartment with plastic windows to normalize the microclimate in the apartment, it must be converted into forced ventilation. This can be done by installing specialized air blowers or split systems with climate control function.

Forced ventilation

In new buildings, a forced ventilation system is installed during the construction phase. And where ventilation of this type is not provided for by the project, it is installed during the repair process.

The principle of operation of a forced ventilation device is to organize traction through special channels by fans.

The supply unit is mounted indoors through a specialized valve, which is installed in a hole in the wall. Outside, the hole is closed by a grill that protects it from debris and various foreign bodies.

Supply ventilation in the form of a system is installed in one room and then distributed throughout all rooms using ventilation ducts or mounted separately in each room of the apartment.

Forced ventilation is installed on natural ventilation household ventilation ducts. It consists of fans that increase the draft of air. Often they are installed in the kitchen or bathroom, sometimes in other rooms where it is necessary to establish air exchange.

Air handling units can be equipped with additional devices: a heater or a recuperator, which will allow heating the cold outside air in winter. And the recuperator will additionally save on heating the room.

Before installing a forced ventilation system, you need to know the following parameters:

• the size of the room or the entire apartment where forced ventilation will be installed;
• air humidity in the room itself and the required value for comfortable stay in this apartment;
• the ecological situation in the area, the level of gas pollution and the traffic of cars;
• the number of people living in the apartment permanently;
• the presence of chronic diseases of the respiratory system and the immune system in residents.

These data will help you choose the right device or ventilation method to restore air exchange in the room.

Combination of ventilation and windows

Anyone who cares about their own health is interested in the possibility of maintaining proper air exchange in an apartment with plastic windows.

There are many options for modernizing natural duct ventilation in apartment buildings... Among the most effective methods, there are those that are installed on the double-glazed windows themselves or already go together with the construction of the windows from the factory.

Windows with a window

The ventilation system for PVC windows, for example, from such a company as www.svetokna.ru, using a window is the most common. The vent provides a continuous supply of clean air. It mixes with the exhaust room air, diffusion occurs, due to which the microclimate is normalized.

With natural ventilation, the appearance of drafts or the formation of condensation on the windows is excluded. The vent can be fixed in several positions. But this design has a lot of disadvantages:

1. Ventilation for plastic windows is installed at the design stage of the window opening. After the entire structure has been mounted, it is impossible to improve ventilation.
2. Such ventilation of plastic windows significantly increases the weight of the structure, which can adversely affect the house itself. Cracks may appear on the walls and window opening of a private house, therefore, before calling a measurer, it is better to consult with specialists from a construction company.
3. Supplementing the design with a window increases its cost.
4. The increase in plastic partitions in the window frame darkens the structure, the light in the room becomes much less.

Self-ventilated plastic windows

Plastic windows ventilated with a self-ventilation system - the best option as for apartment building and for private houses. Supply ventilation is installed on plastic windows and in industrial buildings, i.e. because it helps the main ventilation system.

Such ventilation in plastic windows is represented by slots in the upper or lower part of the plastic window frame. This type of ventilation allows clean air to continuously enter the room through the openings. And thanks to the special arrangement of the holes in the frame, the cold air heats up and enters the room already warmed up.

Self-ventilation in windows has several disadvantages:

1. This ventilation mode does not work in apartments on the upper floors or in private multi-storey buildings... When installing ventilation after building a house, you must carefully consider how to improve ventilation on the top floors without using this method.
2. This ventilation system cannot be installed in already installed double-glazed windows, so you will have to completely change the entire window structure.
3. High cost of windows with the possibility of self-ventilation. Manufacturers increase the cost three or more times due to the complication of the conditions for the production of such structures.

That is why most people use specialized ventilation valves in the form of plastic window handles or combs.

Supply valve on a plastic window

Ventilation in a private house where plastic windows are installed is necessary condition if the owner of the house cares about the health of his family members

You need to ventilate the apartment regularly, especially if another ventilation system does not give the desired effect. Best of all, they will cope with the normalization of air exchange in the apartment ventilation valves to be installed on plastic windows.

The supply valve installed on plastic windows is able to normalize air exchange

The ventilation valve combines several functions, and for proper ventilation it is necessary to select the appropriate device class.

Installing the valve requires a complete dismantling of the glass unit or replacement of the part of the window that is responsible for ventilation. Such upgrades make the structure heavier and significantly affect the cost of the window. But the installation is carried out in less than an hour, and the air exchange is normalized within a day, which speaks of the undoubted advantage of the design.

After installing the supply valve, you need to decide on the control mode: automatic, manual or mixed.

Manual ventilation mode helps the owner to independently control the movement of air masses in an apartment or house. Partial ventilation can be used in the part of the house where it is really needed.

And in automatic mode, the participation of the owner is not required. As soon as the sensors in the valve begin to react to temperature changes, the system supplies fresh air. The temperature is normalized, and with it the air exchange is restored.

Mixed valve control allows switching between manual and automatic control as required.

Plastic window handle valve

It is possible to improve air exchange in sealed structures if you install a special window handle valve.

The handle valve is mounted in the window profile instead of the usual plastic handle. A valve with this mounting system has many advantages:

1. The valve does not protrude beyond window profile, does not clutter up the structure, and does not interfere with the free opening of the window.
2. Condensation often collects in places where the integrity of the window profile is most damaged. The handle is drilled directly into the profile itself, condensation collects there. The presence of a valve handle eliminates the formation of condensation and improves air exchange in the cold season.
3. If forced ventilation works, then installing a valve will create additional comfort conditions and completely eliminate stagnation of exhaust air.
4. The handle valve is a design with a direct-flow supply of clean outdoor air to the room. With a direct flow of air in winter, the valve will not freeze due to the lack of condensation.
5. Only purified air will come from the street, because an air filter is installed on the valve, which can even remove allergens. Such a filter will not cause much trouble: even in a stuffy metropolis, it will have to be replaced no more than several times a year.

This method is a novelty in the world of ventilation systems for PVC structures, so not all experts know about its existence and the possibilities of its installation.

This does not mean that it is difficult to install the valve yourself. The design can be purchased at large hardware stores, and instructions are included with it. Following the rules for collecting and drilling the profile, you can easily install the ventilation in a few minutes.

Combed windows

The most convenient way to ventilate an apartment is to open a window. But completely open window in winter can lead to negative consequences for all family members and for the home itself. Therefore, the developers of window constructions invented combs that provide step ventilation at any time of the year.

The comb is a regulator that helps to fix the window in several positions. The regulator can be installed either on a previously installed window or ordered during the initial installation of the window structure.

Such a system is installed without the power of specialists in a few minutes and does not require large financial costs, and the result exceeds all expectations. This makes comb ventilation the most popular method for improving ventilation in the home.

Ventilation is required for any room: residential, utility or special purpose. About how the ventilation of dressing rooms, smoking rooms should be arranged, as well as how to do it yourself in a room with plastic windows, read on.

Ventilation of the dressing room

The dressing room must certainly be ventilated, otherwise an unpleasant smell cannot be avoided. Most often, there are no heating radiators in dressing rooms, which means that the humidity is higher here: good conditions for the development of mold and microbes. Therefore, you need to take care of ventilation in a deaf room. Few owners know everything about how to organize ventilation in a room.

There are several options for ventilation in the dressing room:

Deaf room ventilation

As a rule, forced-type ventilation is done in blind rooms without windows. Natural air exchange in such cases is not efficient enough, so you have to go for additional costs.

There are several types of units suitable for the ventilation of deaf rooms. Calculations made in accordance with the rules allow achieving maximum efficiency.

If the area of ​​the deaf room does not exceed 40 sq. meters, a supply ventilation unit is suitable, providing an inflow of 120 cubic meters of air per hour. It is hung on an external wall and does not require any special maintenance.

More expensive models equipped with several modes of operation, function in cold weather.

One of the most convenient ventilation methods for a deaf room can be considered an air conditioner with an air supply.

A budget option for a supply unit for a room without windows is to make a supply fan. It can draw air both from the street, if it is installed in an outer wall, and from an adjacent room. Such a solution for ventilation in the room can be equipped with your own hands.

The removal of exhaust air from a dead room is done, as in the case of a dressing room, using a gap under the door or a grate at the bottom of it.

Ventilation of a room with plastic windows

In rooms with plastic windows, ventilation is provided in several ways:

1. Micro-ventilation.
2. Window supply valve.
3. Wall inlet valve.

Micro-ventilation does not require any special costs. This function is inherent in the design of any windows.

But this method of ventilation of rooms with plastic windows has disadvantages:

• cold air enters the room, creating a draft and lowering the temperature;
• in case of frost, the sash of the window freezes, frost and ice accumulate on it;
• air exchange is not controlled.

Window and wall supply valves are very convenient and meet all modern requirements.

The supply valve for ventilation of a room with plastic windows is installed on the window sash. You can choose adjustable or non-adjustable model. The valve creates a flow of air directed towards the ceiling, which mixes with the heated air in the room, creating secondary convection.

The principle of the wall valve is similar. But it is installed in outside wall... It is most advisable to place the valve above the radiator so that the cold air "flows" down, warms up and enters the room. Wall inlet valves for ventilation of rooms with plastic windows can be adjusted manually or automatically. Such devices are equipped with humidity sensors, an air filter. The main disadvantage of wall air inlets is that a hole with a diameter of 5-10 cm must be made in the load-bearing wall.

All air supply devices described above work effectively only in apartments with a normally functioning centralized hood.

Exhaust air from the room flows into the corridor, then into the bathroom or the kitchen. From here, through the general ventilation system, it is pulled out into the street.

How to organize the ventilation of the room if general system ventilation is hopelessly clogged and there is no hood from the apartment? Forced forced ventilation into the room is provided. An air pressure is created, squeezing out the waste masses through inoperative ventilation grilles in the kitchen and in the bathroom, leaks front door... In such cases, exhaust fans built into the ventilation grilles of the kitchen and toilet help to increase the outflow of air.

Dorm room ventilation

They often think about how to make ventilation in a dorm room by installing a shower cabin in it. The owners of the room with its own adjoining shower room also face the problem of dampness and mold.

Directly from the shower stall with your own hands, you can stretch the ventilation exhaust box to the room window, load-bearing wall or common house riser. On the side of the booth, an exhaust fan is built into the box, which is resistant to high humidity. The other end of the pipe is led out of the room. Many owners of dorm rooms hide the made ventilation box under a stretch or plasterboard ceiling.

If the question is about how to make the ventilation in the dorm room complete, you should pay attention to the compact room installations with recuperation. They make it possible to provide supply and exhaust ventilation of the room without conducting air ducts and without changing the height of the ceiling.

Installation for supply and exhaust ventilation of a room is hung on a load-bearing wall and serves the room in which it is located.

The owner can equip such ventilation of the room with his own hands if there is access to the outer wall. To make ventilation in the room you will need polyurethane foam, puncher. In just a couple of hours, an excellent supply and exhaust ventilation of the room is ready.

Tubes with a diameter of 75 - 125 mm are pulled through the holes. One serves to supply street air, filtered and heated. The room air is blown out through the second tube, having previously given off heat through the heat exchanger to the fresh supply air.

One device for ventilation of the room can cope with 25 sq. meters of area, providing a double air exchange. Electricity consumption depends on the outside temperature. Up to -10 is spent up to 0.01 kilowatts per hour, and at -15 and less up to 0.6 kilowatts per hour. Savings come from recuperation.

Smoking room ventilation

Excellent ventilation is one of the most important conditions for the comfort of people in the smoking room and adjacent areas. With poor air exchange, harmful tobacco smoke will spread throughout the floor. How to make ventilation in a smoking room efficient and economical?

The ventilation efficiency of the smoking room is judged by the content of triethylpyridine (3-EP) in the air. In order to maintain concentration in acceptable aisles, in public buildings visited by a large number of people, it is necessary to equip supply and exhaust ventilation systems for smoking rooms.

Air exchange should be 10 - 14 times, but no more, so that a draft feeling is not created.

On average, 1 sq. meter of the smoking room is supposed to accommodate 1 person.

The air flow into the ventilated room should be (in cubic meters per hour for 1 person):

• with strong smoke- 70 - 100 cubic meters;
• with medium smoke emission- 35 - 40 cubic meters.

Simplified ventilation scheme for a smoking room: mixing fresh and exhaust air, removing it. This system is fairly inexpensive to install and maintain. Clean air is supplied to the room, mixed with smoke. At the same time, the content of toxic fumes decreases. A serious disadvantage of such a room ventilation device is the weak efficiency and distribution of smoky air throughout the volume of the room.

The displacing ventilation system for the smoking room is more modern and efficient. The inflow of fresh air replaces the entire volume of the room. The advantages of this method are obvious - you can clearly calculate the frequency of air exchange, and people breathe for a while clean air... The downside is quite expensive equipment.

Therefore, a third scheme was developed based on physical properties tobacco smoke. The air inflow into the smoking room is supplied from below, where ventilation grilles are equipped for this. Warm cigarette smoke rushes to the ceiling of the room, where the exhaust ducts are located. From below, the smoke props up the cool street air. If the air vacuum in the smoking room is 5 Pa compared to the adjacent rooms, the smoke will not spread. And the air movement at a speed of 0.7 meters per second will create quite comfortable conditions for smokers.
