CZ13820U1 - Device for drying up and ventilation of moistened buildings and dwelling spaces - Google Patents

Description

Technical field

The technical solution relates to drying and ventilating equipment of buildings, dwelling houses, recreational cottages and cottages, as well as individual flats, especially for the purpose of drying damp masonry after floods and removing moisture and odors from premises used for recreation.

Background Art

Well-known devices and methods for drying damp buildings and living spaces are based on hundreds of years of proven experience that the most effective ways of drying are the perfect ventilation of wet and damp areas.

Moisture gets into masonry in more ways and ways. First, from the ground, if the building is not completely insulated by a waterproof barrier. As a rule, we fight with this humidity in old buildings, when the insulation technology was at a lower technical level. In this case, the effort is to push the water back into the ground (electroosmosis) while interrupting the capillaries (discontinuing the plaster or exposing the foundations). Furthermore, it is recommended to provide ventilation ducts while using a porous restoration plaster.

Moisture gets into the masonry during a natural disaster, ie during a flood, a storm-damaged roof, a cracked water system, a fire, or even in heavy rain with a side-by-side wind. Of course, the negligence of the property manager, when it flows through the roof or for other reasons.

Moisture gets into the walls, but also in buildings and areas where previous deficiencies are not found. Then it is air humidity, which we also have to defend. With varying air temperatures in these spaces, the relative humidity of the air changes as well, and at a certain temperature, the air vapor condenses on the cold walls. This problem is well known to cottagers and cottagers when they return after a week to recreation and smell the unpleasant smell of masonry. It runs quickly to vent and flood, bringing the temperature and humidity ratios back to normal. Mold and fungus growth on walls, floors and ceilings can also occur in long, unventilated areas.

Remediation and drying of damp walls after a disaster is carried out as a standard by knocking wet plaster on to bricks or stone, intensely spontaneously or pressure (ventilators) ventilating and possibly heating. The used electric dehumidifiers usually draw in a large amount of indoor air, the steam contained in the exchanger condenses (like in the freezer) and drains the dry heated air into the damp space. In this way, a moisture handicap (gradient) is created in the enclosed space, and the water from the walls evaporates intensively, thereby drying it quickly. In this intensive drying process, we need to monitor not only the time but also the cost, safety and operational aspects.

Floods in the Czech Republic in 2002 showed that the total required number of dryers was considerable, thus also the cost of their acquisition. Operating costs were not negligible either, since drying takes several weeks, depending on the level of masonry saturation with water, and with regard to its thickness, the material used and the position in the building.

The biggest disadvantage of condensation drying of masonry and heating of ventilation air is energy intensity, considerable financial costs of acquisition and operation. This system also requires the occasional presence of a supervisor in case of failure.

The aim of the present invention is to eliminate the aforementioned drawbacks and to reduce the long-term drying and ventilation of wet buildings.

The essence of the technical solution

The essence of the technical solution is that we do not try to condense the air humidity, but we divert it together with the cold and heavier air from the humidified space, while the exhausted air

-1 CZ 13820 Ul is replaced by warmer, lighter and drier air from the attic space so as to prevent cold humid air from whirling on the floor or mixing it with dry air. This is achieved by appropriately directing the hot air exhaust nozzle under the ceiling, by correctly detecting and evaluating the temperature differences by sensors and by appropriately positioning and switching functionally interconnected pairs of low pressure fans with low power consumption. Description of the drawings in the drawing

The accompanying drawing schematically shows an arrangement of a device for drying wet areas, in one embodiment of a pair of fans, and in particular the part in which the essence of the technical solution rests.

Examples of technical solutions and industrial applications

The equipment for drying of damp areas, whose moistness is caused by their construction, natural disaster, imperfect protection from ground moisture or only air humidity from irregular use of the building and its non-ventilation, consists of three basic units. The first is the suction section of the humid cold air formed by the suction unit i provided with a suction port 2 sucking from the floor of the dried room. The second is the filling section of dry and heated air from the attic space between the roof trusses near the ridge, consisting of a filling unit 3 with a discharge nozzle with a flap 6 and a suction channel 4 provided with an inlet filter 5. air 8 and cold air sensor 9.
