Why blow from ventilation to the apartment

Ever wonder why, even with all the windows and doors closed, your house still feels drafty? This is a prevalent problem that many homeowners deal with, and the ventilation system is frequently to blame. The causes of unwelcome drafts that may enter your home through the ventilation system will be discussed in this article.

First and foremost, it’s critical to comprehend how ventilation systems operate. Although they are essential for preserving indoor air quality and controlling temperature, they may unintentionally cause drafts. Air can circulate from the outside and throughout the living areas thanks to ventilation systems, which usually consist of ducts running throughout the house. On the other hand, these ducts could become entry points for cold air into the house if they are not adequately sealed or insulated.

Drafts from ventilation systems are frequently caused by ductwork leaks or gaps. Ducts may split or fracture with time, particularly in older or poorly maintained homes. Warm air is forced through these ducts when the heating system is operating; however, if there are leaks, some of the warm air may escape and be replaced by cold air drawn in from the outside, resulting in a discernible draft.

Inadequate insulation surrounding the ductwork can also make the problem worse. In the absence of adequate insulation, ambient temperature can have a big impact on the air temperature inside the ducts. For instance, the air inside attics and crawl spaces can rapidly lose heat if ducts pass through them; this can cause cold air to be blown into the home’s living areas.

The layout and design of the ventilation system itself should also be taken into account. Poorly designed systems occasionally have vents placed close to windows or doors, for example, where they can easily draw in cold air from the outside. This may result in a steady stream of cold air entering the house, making it challenging to keep the interior temperature at a comfortable level.

In conclusion, ventilation systems can cause unwelcome drafts if they are not properly maintained or designed, even though they are necessary to maintain indoor air quality and comfort. In order to reduce drafts and guarantee a more comfortable living environment all year round, homeowners should take care of problems like duct leaks, insufficient insulation, and poorly designed systems.

Ventilation system: types and principle of operation

Comfortable conditions are created for occupants of a house or apartment by well-functioning ventilation. It matters a lot, after all, what kind of air we breathe—fresh or tainted with amber from fried cutlets. No one is aware of the system’s work when it operates normally. Оогда же запотевают стекла на окнах, не выветриваются запахи пищи, в комнатах – застоявшихся воздух, и что еще хуже дует из вытяжки в квартиру при закрытых окнах, становится понятным – нет вентиляции.

Three types of ventilation are used in the construction:

1. Natural ventilation. The principle of its action is the natural movement of the air. Due to the different temperatures and the pressure of the atmosphere in the room and on the street, the air enters the house through the windows, doors, the available cracks. Steply flowing throughout the house – goes through the outlets in the bathroom, in the kitchen. Such a course of air masses occurs when nothing prevents them from.
2. Mechanical ventilation. Its work takes place using ventilation equipment. Under its influence, fresh air enters the apartment or house, and the worked out is removed outwardly.
3. Mixed ventilation. This is the most common system when the flow of air occurs naturally, and the withdrawal – using the exhaust installation.

An influx and exhaust ventilation system is necessary for their proper operation. The system does not exist in the absence of such a basis.

Take note! An ordinary paper sheet or a candle flame are used to verify that the vendes’ work is accurate. Simply open the window and place the sheet or candle next to the ventilation grill to accomplish this. It functions properly when the sheet is drawn to it or when the candle’s flame is directed toward the hole. The system is broken if opposite processes take place or nothing happens at all.

5 reasons why blow from ventilation to the apartment

1. If such a problem arose in winter, after snowfall, then the reason that blows from the hood to the apartment with cold, there may be a freezing of the ventilation.
2. Clogging with garbage, bird nests, soot.
3. Accumulated steam and cold air.
4. A draft arising in a large room.
5. The ventilation pipe is located in the wind support area formed by the skate of the roof. Increased pressure is created and instead of traction from the room, air blowing inside the house. Such problems arise in private housing construction.

Perhaps "guilty" plastic windows

Natural supply and exhaust ventilation systems are installed in apartment buildings during construction (spent air masses go into special holes in the sanitary room and in the kitchen). SNiP 2.08.01-89 "Residential buildings" provides this. He should go through all of the windows, doors, and open spaces to enter the living area. However, windows made of metal and plastic can now be installed in apartments thanks to modern civil construction methods. The installation of natural ventilation is in conflict with them since they are stacked and prevent air from entering the apartment freely.

The metal-plastic windows and doors with seals are the cause of the exhaust air coming from the ventilation system. How is the procedure progressing? When in use, kitchen extractors can "pull" air from the entire apartment in addition to absorbing evaporation and food odors. In the ventilation, this causes reverse traction. In other words, because the room is sealed off, fresh air from the street does not enter, and unpeeled air masses from ventilation take its place.

How to make ventilation work correctly

It is necessary to determine whether air movement under natural ventilation conditions will be required before attempting to "diagnose" the system breakdown. To accomplish this, open the bathroom door, the window, and the kitchen hood. The reverse traction issue is resolved on its own if the candle’s flame veers toward the hood.

What should be done if the flame shifts to the other side and continues to blow into the apartment through the ventilation system? The duct needs to be cleaned. To accomplish this, the grate is taken apart, and the ventilation system’s walls are cleaned of dust and soot. A specialized tool is used for cleaning. A number of kitchen brushes are fixed on the stick if no one is there. In a similar manner, the apartment’s other accessible exhaust channels are cleaned. The traction is then examined once more. If cleaning doesn’t help, there are other activities.

Crucial! The room in which the ventilation systems are installed determines how well they function. In contrast to the restroom, the kitchen has a higher temperature and a larger amount of absorbed air. Additionally, one channel "works" with reverse traction when the temperature is higher, improving the craving in that channel. When the kitchen ventilation is fitted with a tedding diameter, the toilet channel will function normally again.

Windows that are hermetically closed prevent fresh air from entering the space. By installing a supply valve on the window frame, the issue can be resolved by "tuning" the frame. It is airtight even when the windows are closed.

Replacing outdated interior doors with new ones without the lower bar in the doorbox will enhance natural ventilation. If this problem’s solution is too expensive, you can employ some "tricks." A ventilation grille is inserted or multiple holes are drilled in the lower portion of the current doors. There won’t be any drafts, but there will be some organic air movement.

The check valve is one easy way to increase air circulation. Its primary objective is to obstruct the worked masses’ entry back into the room from the hood. Depending on the vent system’s design features, they can be installed either vertically or horizontally.

Why is the correct ventilation work important important

Inadequate ventilation can cause a variety of illnesses to settle in the apartment when exhaust air is blown into the house rather than being removed. For instance, a high carbon dioxide content can lead to headaches, general ill health, and depression.

A person who sleeps poorly will feel even more sleepy the next day due to too humid and stale air in the bedroom. Resting with windows open is advised by doctors. This condition is unachievable in the winter because extended building ventilation increases the risk of heat loss.

Crucial! The spent air, which blows in the opposite direction and is not exposed to the outside, aids in the growth of soot and moisture on the walls, which eventually causes mold to appear. Fungi that cause mold can cause allergic reactions, respiratory issues, and other issues.

It can be annoying to feel a draft from your ventilation system, particularly when you’re attempting to maintain a warm and comfortable home. Even though it might seem counterintuitive, knowing why this occurs can help you deal with the problem successfully.

A drafty ventilation system may be caused, in part, by inadequate sealing or insulation in your house. Your home is easily invaded by outside air when there are cracks or leaks in your walls, windows, or doors. This causes drafts and lowers the effectiveness of your heating system. Your home’s overall comfort can be increased and these drafts can be reduced with the help of proper insulation and sealing.

Your ventilation outlets’ layout and design should also be taken into account. A noticeable draft may result from vents that are positioned in areas where they are directly facing windows, doors, or other openings, which can draw in cold air from the outside. Redirecting airflow and preventing drafts can be achieved by installing deflectors or repositioning vents.

Drafts can also be caused by the state of your ventilation system itself. Air can escape from ductwork before it enters your living area due to leaks or other damage over time. Your ventilation system can help detect and resolve these problems with routine maintenance and inspection, resulting in effective airflow and few drafts.

In summary, drafts from your ventilation system could indicate a number of different underlying problems, such as inadequate insulation, misplaced vents, or issues with your ducting. You can reduce drafts and make your home a more comfortable place to live by taking care of these problems with appropriate insulation, thoughtful vent placement, and routine maintenance.

Maintaining adequate ventilation in homes is essential for preserving the comfort and quality of the air within. On the other hand, poorly planned or maintained ventilation systems can occasionally result in problems like drafts or "blow" into the living areas. This airflow can cause temperature swings, discomfort for occupants, and even inefficiency in energy use. For homeowners, knowing why this occurs is crucial. Unwanted drafts can be caused by a number of things, including poorly installed ductwork, clogged vents, and broken dampers. Homeowners can enjoy a more comfortable and energy-efficient living environment by addressing these issues through routine maintenance and possibly investing in upgrades or adjustments to the ventilation system.
