Traditional approaches to ventilation in the house
As a rule, passive convection systems consist of two parts. The first should ensure the natural supply of air. To this end, special inflow holes can be provided in the houses of various projects. Especially good it can be seen in houses of old construction. In them, such apertures were covered with a visor and protective grid, in houses of later construction projects were limited to gratings.
And had such openings in the outer wall under the kitchen window behind the radiator of the heating battery, so that the air, getting into the house, was heated. In houses of the era of developed economy, the influx of outside air was provided due to natural gaps of windows and doors and periodic ventilation by opening the windows, etc.
In turn, in the office premises, which included bathrooms and toilets( later combined bathrooms), kitchens, barred windows were installed, having through the knee exit to the ventilation shafts common to the apartment riser and being the public utilities of all the tenants of the house.
Through these ventilation windows and shafts, the air "exhaustion" due to the temperature difference was discharged outside. Such a system works well between autumn and summer. At high summer temperatures, natural convection becomes more difficult. That, however, may not at all say that there is poor ventilation in the apartment or it is completely clogged.
Ventilation problems
But time flies, and plastic windows and doors have become common in our homes. And taking into account modern window and door metal-plastic systems, hermetically sealed armored entrance systems, the option of supplying fresh air through their leaks is increasingly not justified.
And in apartments that do not have access to outside air there are external signs of clogging the channels of the shafts or knees of ventilation. Here and the appearance of condensation on the windows, and moldy ceilings and walls, and unimaginable smells, wandering where they are not allowed, and other delights.
Checking the obstruction of ventilation
So, how to check ventilation in the apartment? First, with closed door and window systems, a sheet of tissue paper is brought to the ventilation grilles. If there is no traction, the magic piece of paper simply falls( according to the law of universal gravitation) to the floor. Then the window leaf opens and opens, and the incantations with cigarette paper are repeated. If the sheet still slightly adheres to the grate, you need to think about how to ensure the flow of air.
Construction shops and markets offer a sufficient number of modern valve systems, even with opening automation controlled by signals from special sensors.
In this case, if the thrust is not resumed, it is necessary to check the second part of the ventilation system, as previously mentioned, it is hidden behind the grilles of ventilation windows in the bathroom, toilet or kitchen. It should be taken into account that in houses of earlier construction, the in-apartment exits to mines are more complex and may have more than one channel. In later buildings, there is usually one common channel for reaching the mine.
This very channel can clean the owner of the apartment with mysterious smells. Since the common well is a public engineering system, it is not allowed to service its private individuals. And in order to avoid trouble, breaking his head, how to clear ventilation in the apartment, it is better not to do it, although often, as they say, "who dared, he ate".
Should I act on my own?
But check out the channel outlet in the mine well just. To do this, remove the grate and carefully cleaned up accumulated debris. And there are a lot of things there, from the construction remains of the commissioning period, to fallen leaves and dead organics, which in its time ran into appetizing smells and did not find the way back.
If the vacuum cleaner with a brush did not bring the expected freshness into the house, there are variants of the obstruction of the mine itself. The reasons can be different. This and stuck branches, it is not known how trapped inside with the garbage deposited on top, and the results of independent re-planning of neighbors, etc.
As already mentioned, in this case you need to contact the service organizations. And you have less trouble, and they are pleased. In the old days, chimney-sweeps used to walk around the cities and an obligatory attribute of their equipment, except for brushes and brushes, was a ball of its own, with the size of a core, on a solid rope. Dropping it into the chimney, the cleaner cleared the plugs and locks from soot and debris. This is the principle.
But deciding to use it, you need to be prepared, that neighbors can have questions, where did it come from so much incomprehensible rubbish poured into the kitchen sink, or worse, why did a newly constructed drywall ceiling hang onto a expensive imported refrigerator or oven?
