Why in the basement is cold. Why basement is the coldest place in the house? Ventilation in the basement. Qualitative characteristics of the basement

It happens, we wonder about why the basement is the coldest place in the house or how to make it so that it is. And if the basement in a private cottage is not? What else can serve as a special multifunctional room designed for storing winter spins, home utensils, sports equipment, communications? What is the difference between the cellar from the basement? The advantages and disadvantages of each of them are briefly described in this article.

Cellar or basement?

Answering the question, it is important to understand the goal-setting, purpose of one or another room. The basement is an underground non-residential part of the building. Often it is adaptable under the workshop, the direction, the garage and the other useful area of \u200b\u200bfree layout. It is characterized by durability, a high height of a person, the lack of natural sunlight, the constancy of the average daily and average annual temperature modes. When arranging it to a depth of 2 meters and below the fork of the average annual temperature ranges within +5 - + 10ºС, both in the heat and in the lung frost, even when no one lives in the house and it does not hear. That is why the coldest place in the basement. It is usually shutdown under the kitchen, but can pass around the perimeter of the entire residential building.

The cellar serves as an exclusively place of storage of blanks. This is a kind of spacious refrigerator, equipped with shelves and partitions. It can be equipped with a house, in the same basement, or to partially stand in the country area, more often on dry ousters, elevations to minimize contact with groundwater. Compacted compared to the "fellow", you can only look into some designs to get the billet bank from the shelf. Its size will depend on the needs of the owner and the intended volume of blanks. Finance is less cost.

On this question, the average student studying the basics of physics will be able to answer with the go: the cold air is heavy, dense, it sinks down. This is the so-called natural convection. And the heat formed from the roof of the roof of the solar rays does not reach the lower room. But this is not the only possible answer option.

Qualitative characteristics of the basement

The basement requires significant investments during construction and finishing (about quarters from the estimated value of the whole house). Why? The basement is the coldest place in the house. So that this statement corresponds to reality, a high-quality structure of the structure is necessary, requiring the definition of the structure of the soil, the implementation of land (for the preparation of volumetric pit), drainage (for removal of surface and groundwater), concrete works. It is also necessary to make a clay castle of a dense tamping, a waterproofing sand-gravel pillow, handle walls, gender (for example, bitumen emulsions). After all, the main enemies for such a premises are water, dampness, shaggy, air inadium. From here, the main parameters that can extend the service life of the room are important: the resistance of the walls to the pressure of land, destructive effects, high waterproofing and ventilation properties.

Thermal insulation - base bases for basement

Why the basement is the coldest place in the house? The answer to the question is good thermal insulation, providing protection for overlapping, doors, hatches, walls around the perimeter of the premises from the freezing.

The use of ultra-modern insulation materials (polystyrene foam, fibrous cotton insulation), as a rule, from the outside of the building, will avoid the formation of condensate, fungus and mold, as well as 15-20% will save thermal energy that will not leave the house, consult heating Unheated premises.

Did you think about why the basement is the coldest place in the house, and how to ensure the optimal level of temperature in this room?

The basement in a private house is used for personal purposes. Since in this part of the house is cold, then in 90% of cases on the basement, food is stored: fruits, vegetables and conservation. Sometimes the workshop, gym, sauna is placed indoors.

Regardless of the purpose of using the basement, it requires a well-coordinated air circulation. It is possible to achieve this by carrying out ventilation systems or the organization of natural air exchange. You can cope with the task yourself or resorting to the help of the wizard. The volume and complexity of the work will depend on the complexity of the ventilation structure of the basement in the house and size of the room.

With properly equipped natural ventilation, the coolness will be stored inside the basement regardless of the time of year. But if the installation work on the arrangement of the ventilation system was carried out with a violation of technical recommendations, it would have to ensure artificial or forced ventilation. Conducting such a communication system does not cost without special devices that are not suiced. For example, air conditioning.

Why ventilation in the basement is such an important question?

The absence of constant air circulation indoors does not contribute to the elimination of excess moisture, which is subsequently settled on the walls, contributes to the formation of fungus and mold. So that this does not happen, one-storey house with the basement provide a competently designed ventilation system or air conditioning.

Features of the design of the natural air duct

The coordinated operation of the ventilation system in the basement is possible with the proper placement of the lower part of the exhaust pipe. It is placed under the basement ceiling.

If the basement is planned for storage of products, the pipe is placed above the rack or shelf, where fruits and vegetables are stored.

The upper part of the exhaust pipe is output through the built overlap outside. Its end is removed from 30 to 60 cm from the roof, which minimizes the ingress of the basement of snow and melt water from the roof.

Thoughtful in the question, why the basement is the coldest place in the house, consider the condensate inside the pipes, and so that the moisture does not fall inside the basement, the cellar establishes a special tank for collecting water.

Pipes for ventilation arrangement in the basement are used any. These are PVC or asbestos-cement products, characterized by efficiency, thermal conductivity, durability. That is why the basement is the coldest place in the house.

Why is the basement cool?

Cold air is denser and harder warm, therefore it descends to the lower level of the house - to the basement. Accumulating here, the cooled air forms a microclimate, explaining the reason why the basement is the coldest place in the house. Passing the way from the top floor to the basement, the air masses are gradually cooled, and warm air rises upstairs. Thus, natural convection is formed - heat exchange between different temperatures by air masses.

Now you know the reason why in the basement is the cooler, and what contributes to this. The considered example of natural ventilation is simply implemented, because it is easy to cope with this task yourself. But due to the need for a basement, special systems of air exchange and air conditioning are mounted, and with such a question it is better to contact the master.

Try to check the ventilation arrangement in the basement. If you are planning to build a house, then pay special attention to this session. It is desirable to develop a separate project to prevent problems occurring during the further operation of the premises.
