How natural ventilation in the kitchen should actually work: how to achieve it

In any of the cleanest apartment in which the hostess regularly cleans up and continuously erases dust and specks from everywhere, there is a place where fumes, soot, harmful fumes and even poisonous gases are produced. This place is called the kitchen. Tasty and healthy food is prepared in the kitchen, but smells from heat treatment of food, splashes from boiling pots and pans, smoke from unburned fuel. A person does not need to breathe all this good at all. Clean air is much more pleasant and healthy. And the replacement of a harmful atmosphere with a useful one in the volume of the kitchen is due to ventilation, which can be natural, forced and combined. Natural ventilation in the house and in the kitchen area is ensured by the construction of the house. Forced - is built by the owner of the dwelling. But not everyone knows how the ventilation system of an apartment, especially a kitchen, should actually work. This requires knowledge from the field of physics, hydro- and aerodynamics of gases, heat engineering and chemistry. This is the direct responsibility of the builders, and the residents need clean air.

Types of ventilation

In houses of different designs and for different purposes, ventilation systems are built in different ways. The design of the system depends on the number of storeys of the house, on the material of the walls, on the design of the windows.

On the basis of the initialization of the gas flow in the room, ventilation is natural and forced. In the first case, the air flow moves in the room due to the temperature difference inside and outside the house. Warm air rises upward, goes out through the ventilation duct of the system, the released volume is filled with fresh, colder air - from the street. If in the recent past the inflow went through the cracks in the windows and doors, now, with a better quality construction, it is necessary to specially equip devices for the passage of external air into premises. Air valves are installed in the walls of the house and in window structures, allowing air to pass in one direction. Natural ventilation requires the utmost cleanliness of the ventilation ducts. From this point of view, ventilation shafts do not meet all sanitary requirements, therefore they are replaced with air valves installed directly in the walls of the house. Each room has two valves - outlet (under the ceiling) and supply (below).

Forced ventilation has two types - supply and exhaust. The names themselves indicate where the fan is installed. The supply fan organizes the air flow from bottom to top, along the wall. The exhaust fan is designed for a certain capacity in accordance with the air exchange rate.

The supply and exhaust option assumes the presence of a spirit of fans at the bottom and top of the room. The mixed system allows different types of installation in different rooms. It is recommended to install an exhaust fan in the kitchen.

The specifics of ventilation in the kitchen

The kitchen is a difficult object for choosing the type of ventilation system. Each option in specific conditions shows either advantages or disadvantages.

There is natural exhaust ventilation in every kitchen. It has low performance, but it works reliably in constant mode. Warm air rises to the ceiling and goes into the ventilation shaft. The system removes cooking odors and unburned fuel residues. High-quality removal will occur with an absolutely clean ventilation duct. Channels must be additionally arranged within the walls of utility rooms. The quality of airing of the whole house or the whole apartment is increased with an additional start of the air flow from other rooms. To intensify the flow of removing odors and harmful substances, an extractor hood is mounted above the stove.

The best ventilation option in the kitchen

A high-quality efficient ventilation system with heat recovery is well suited for a large expensive country house or for an elite city apartment. Recuperation allows you to return part of the energy spent on ventilation and use it in the same process. Such a system allows you to regulate the level of humidity in rooms, maintaining it within a comfortable range, to remove excess carbon dioxide and other impurities in the air. The temperature drops by several degrees. The fan in the system works alternately - either to supply fresh air into the room, then to remove waste air.

The outgoing air gives off its heat to the oncoming flow entering the room. This process provides a small amount of energy savings for heating the home.

In expensive real estate, it is advisable to mount a powerful hood with exhaust air outlet through a hole in the wall.

In the cheaper version, the best solution is natural ventilation in all rooms. If a hood is installed in the kitchen, then its emissions are directed through a hole in the wall, with the installation of a check valve. It will protect the interior from the penetration of cold outdoor air. Natural ventilation works continuously, even in the absence of electricity.

Conclusion

All people understand differently what comfort is in the house. One needs a beautiful setting, another needs comfortable furniture, but everyone needs fresh air. Therefore, a workable ventilation system, especially in the kitchen, is needed by everyone. People have come up with many different options for providing themselves with fresh air. Everyone equips this system in accordance with their needs and capabilities.
