Description

Technical field

The subject of this utility model is a device for drying wet components of houses and buildings such as walls, floors and other parts thereof with jet-treated (heated and dried) air.

Ϊ Buildings are affected by moisture both on its long-term effect, eg on buildings with poor or damaged insulation, and sudden penetration of moisture due to various adverse natural and operational events. Of course, permanent humidity has a fundamentally detrimental effect on the utility properties of the building, which manifests itself in several ways, starting with the increased costs of heating a wet building and ending with the formation of molds and their impact on the health of people who have lived in the building.

Drying of objects affected by moisture can occur to a certain extent over time, but in practice the time required is too long. For objects that are permanently affected by water, any natural drying out is prevented by the ingress of additional moisture. Thus, for real drying to take place, it is necessary to use artificial means, that is to say, a variety of devices operating using different physical principles.

The simplest and most commonly used drying devices include various heating systems and condensation or moisture absorption systems. For equipment that uses condensation or absorption, it is appropriate to close the room in which the equipment operates in order to achieve adequate efficiency. Ventilation systems then require intensive room heating. These conditions limit the use of the room »during the work, but in particular entail the necessity of heating much larger volumes of mass than just the part of the building that is actually affected, and considerable heat loss by leakage into the space. Thus, the efficiently utilized amount of energy is only a small part of the energy expended, the operation of the device is unnecessarily expensive, and the entire process takes longer than necessary.

The essence of the technical solution

In order to overcome the described drawbacks of the known building drying devices, a utility according to this utility model has been developed, which comprises at least one auxiliary structure provided with an air inlet and outlet and a space seal between the auxiliary structure and the dried part of the building.

The sealed auxiliary structure together with the dried part of the object (eg wall or floor) creates a closed chamber into which heated and pre-dried air is supplied by the fan. The air flows through the chamber, saturates with moisture and leaves the chamber again with some of the moisture collected from the object. With this solution, only a smaller volume of construction (masonry) and air is heated, so energy losses are

70GB Ul significantly lower than when drying large or unclosed spaces. Heat exchange occurs only in the chamber between the object to be dried and the auxiliary structure, the building itself can remain closed and does not ventilate into the open space. The air to be treated is supplied from the outside and after passing through the drying chamber it is discharged again. This auxiliary structure can be used for a shorter or longer period of time as required.

A further reduction in energy loss can be achieved by providing the auxiliary structure of the apparatus with a layer of thermally insulating material. This reduces the amount of heat escaping into the room outside the dried part of the building structure. J

In view of the practical use of the device in different areas, it is advantageous to equip the entire system with at least two auxiliary structures with respective supply and exhaust air distribution. Individual structures can be used separately or simultaneously. Such an arrangement will increase the surface to be dried, while facilitating the handling and positioning of the smaller parts.

Giant. 1 is a schematic representation of the device according to this utility model; FIG. 2 shows its possible application in drying the inner wall.

Exemplary embodiment

The device according to this utility model is schematically shown in the attached Fig. 1. Inlet air 1 is used for air intake from outside, in which a fan 2 and an electric heater 2 are installed. 5 and the dried wall 6. The second branch of the pipeline downstream of the manifold 4 extends into the space between the second auxiliary structure 5 'and the dried wall 6. In this branch, a further valve manifold 4' is installed, which allows for a possible extension. add another auxiliary structure and thus increase the _Λ area to be dried. After passing through both drying spaces, the air is led through the exhaust ducts 7 and 7 '. Both discharge pipes 7 and 7 'are individual in this case, but they can also be connected to the joints. medicinal branches.

FIG. 2 shows a part of the device according to FIG.

1, comprising only one pipe branch and one drying space formed by one auxiliary partition and a dried wall.

Industrial applicability

The device for drying damp walls and other components of constructions according to this utility model is very well usable for drying houses and buildings in an enclosed space and brings significant energy and cost savings compared to the devices used so far.
