ES2895271A1 - Forced ventilation humidity exchanger (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

The "moisture exchanger for forced ventilation" consists, basically, of a series of tubes, elbows and fan arranged in such a way that it favors the decrease in present humidity where it is installed (subsoil, basement, garage. Crypt, etc.) by renewing the air. The "moisture exchanger for forced ventilation" is an apparatus that is as a bridge between two spaces with a percentage of different moisture and acts by the exchange of air between both spaces. Forcedly favors the subsoil vent where it is installed, facilitating the expulsion of moisture to the atmosphere, by air exchange between the two media, subsoil-atmosphere, so that the air with a large presence of water is replaced by The existing one on the outside (atmosphere) with less concentration-presence of moisture.

Description

DESCRIPTION

Forced ventilation moisture exchanger

The invention to which we refer in the body of this descriptive report and with the help of the accompanying complementary drawings, deals with a new "HUMIDITY EXCHANGER BY FORCED VENTILATION"

The objective pursued is the elimination, or mitigation of dampness existing in the subsoil, for various applications, essentially maintenance of buildings, archaeological sites, monuments, works or constructions, by way of example, not limitation. Similar devices are not currently known, except for bilge pumps for floods, but for purposes other than maintenance and prevention, which the invention whose patent is sought, pursues.

It is a device that favors forced ventilation of the subsoil, of the place where it is installed, facilitating the expulsion of humidity into the atmosphere, through the exchange of air between the two media, subsoil-atmosphere, so that the air with a large presence of water, it is replaced by that existing outside (atmosphere) with a lower concentration-presence of humidity.

The same air exchange process achieves a drastic reduction in the appearance of soluble salts, which form by capillarity in the outer areas of the buried walls.

The novelty of the system lies in two fundamental aspects:

1. The combination of an internal circuit with forced ventilation (with the help of a motor-fan) that favors the flow of air from the surface to the subsoil.

2. The perforated design of the vent.

The new system materializes in a system that consists of a tube (tube A - figure 1) perforated in its walls of plastic or metallic material of variable length that ends in a superimposed elbow (elbow - figure 1). Inside this tube (tube A - figure 1), there is another plastic or metal tube, not perforated on its walls (tube B - figure 2). This inner tube (tube B - figure 2) is slightly shorter than tube A and has an electric (or internal combustion) motor installed at its base (lower part of the tube). At the upper end of tube B, there is a perforated cap where another tube is inserted (tube C - figure 1 and figure 2) through which the air from the atmosphere is taken and will be introduced into the circuit.

This last tube (tube C - figure 1 and figure 2) that takes in air, runs inside another elbowed tube with a larger diameter than tube C, which is joined to tube A as an extension of it and has the same diameter as the latter, and that functions as a chimney (exhaust of air to the outside -atmosphere).

Tube A (figure 1) is, in its lower two thirds buried, and perforated throughout this extension (2/3 buried) to favor contact with the ground where it is intended to establish an air flow (exchange) with which it penetrates from the outside, which will favor the elimination to the outside of the air with higher humidity from the subsoil.

The buried part of pipe A (2/3 of its length) is covered with a net (grid) or plastic mesh that will prevent the earth where it is buried from entering the circuit with the risk of clogging. The size of the pores or holes in the net or mesh will vary depending on the composition of the terrain.

In the upper part of Tube A, not buried (1/3 approx. upper) and next to the Elbow, there is a hermetic box with the motor connections, located at the base of tube B, either cables for the electric motor or sleeves of fuel supply.

The engine, once started, generates an air current that flows through tubes A, B and C, fulfilling the function of "intercooler", air exchanger, injecting clean air with low humidity and expelling humid air. of the underground.

The Elbow, attached to Tube A, is joined by a manual fitting system and without the need for supports, and can be separated at any time, facilitating system maintenance tasks, without the need to remove the entire " moisture exchanger" .

For the correct operation of the subsoil forced ventilation system, a hole must be made in the ground to insert the "moisture exchanger" up to the mark indicated on the side of tube A, (approx. lower 2/3 of it.) Once placed in the perforated ground, it will be covered, buried, with the same material that has been extracted from the ground.The lid of the hermetic box will be removed, connecting cables or sleeves for the correct power supply and start-up, proceeding cover the junction box again.

After this process, the "forced ventilation moisture exchanger" will be ready for operation.

Once started, a suction current of air will be created, taking it directly from the surface (atmosphere) and taking it to the deepest end of the "humidity exchanger" through tube B. The injection of air from outside causes a constant flow of air that reduces the existing humidity in the subsoil by expelling the humidity from the subsoil.

The motor installed at the base of tube B will have two directions of operation, so the air flow can be by penetration through tube B and expulsion through tube A, or vice versa, penetration through tube A and expulsion. through tube B.

The "forced ventilation moisture exchanger" can be manufactured with metallic materials, PVC, plastics or any other type of material to use, carbon etc., and can have different finishes, colors, textures, etc., for its correct integration in the places where it is installed.

The dimensions or sizes may vary, depending on the objectives and places of installation, although the optimal size is that shown in figure 5, which is a companion to this report. For a better understanding of the general characteristics, previously exposed, FIVE DRAWINGS (figures) are attached that show us graphically represented and in schematic form, a case of graphic realization of the "forced ventilation moisture exchanger" , object of this record, making note that given the condition eminently informative of the drawings in question, the figures designed in them must be examined with the broadest criteria and without any limiting character.

The figures represented in the attached drawings, expose as specified below:

1. Figure 1.- Section of the "forced ventilation moisture exchanger", external view.

2. Figure 2.- Section of the "forced ventilation moisture exchanger", internal view.

3. Figure 3.- Operation diagram of the "forced ventilation moisture exchanger ", direction of operation 1.

4. Figure 4.- Operation diagram of the "forced ventilation moisture exchanger ", direction of operation 2.

5. Figure 5.- Longitudinal section with dimensions, for proportion of sizes.

Considering that each and every one of the parts that make up the "FORCED VENTILATION HUMIDITY EXCHANGER" has been fully described, it only remains for us to record the possibility that its different parts may be manufactured in a variety of materials, sizes and shapes, and may also be introduced into its Constitution those variations of construction type that practice advises, as long as they are not capable of altering the essential points that are the subject of this Invention Patent registration.
