Abstract

Ventilation system disposed in a building construction. The intention is, on the one hand, to provide a feed of fresh air originating from outside into a room while, on the other hand, recirculation of air originating from the room must be possible in that room. For this purpose, a ventilation system is present which extends through the wall of a building construction so that air can be drawn in through it from outside. Feed of this air is regulated by a valve disposed in the duct. Furthermore, a feed opening for air originating from that room is present in this duct which extends to a heat exchanger. This air feed can also be opened and closed with the aid of a gate valve. A common operation is present in such a way that, when the opening for outside air is closed, the opening for recirculation is opened to the maximum extent, and vice versa. A manifold is present on the end of the duct which can be connected to a heat exchanger, in particular the underside thereof.

Description

Structural construction and ventilation system

The present invention relates to an architectural construction comprising a partition wall which delimits an interior space with respect to the exterior space, wherein said separation wall is provided on the inside with a heat exchanger for heating / cooling said interior space, an opening near said heat exchanger said partition wall is provided for supplying ventilating air from the outside space to said inside space, wherein said opening debouches at said heat exchanger and a valve for supplying ventilating air is arranged in said opening.

Such a construction is generally known in the prior art. In order to provide air from outside on the one hand in winter, but on the other hand to prevent this cold air from causing an unpleasant feeling to those in the room, it has been proposed to provide an air supply opening in the partition 15, through which air from outside to can be moved inside and connected to a radiator used for heating. As a result, the incoming air is heated before it flows freely into the relevant room. As a result of the temperature difference, a chimney effect is moreover created in this way, which makes it possible to suck in air from outside under all circumstances.

A valve may be used for dosing the air from outside.

However, it is not desirable under all circumstances to suck in air from outside. In such cases, the opening can be closed, but the heating capacity of the radiator in question is not optimally used due to insufficient airflow. As a result, the temperature of the air stream emerging from the radiator or other heat exchanger is increased, which can produce an unpleasant feeling and the heating efficiency is lowered.

The object of the present invention is to provide an improved structural construction with ventilation through a partition wall.

This object is achieved with a construction described above in that a pipe is arranged on that mouth of said opening, which pipe extends to said heat exchanger and in that pipe there is a supply opening for air originating from said inner space.

According to the present invention, in addition to the supply opening for supplying air from the environment outside the partition wall, there is a supply opening in the conduit with which air can be displaced from the room into the conduit. As a result, recirculation takes place. In this way, if the supply of air from outside is restricted, the heating or cooling capacity of the heat exchanger can be fully utilized because air from the room is supplied to the heat exchanger via that conduit.

In particular, the conduit can be a tube.

It is possible to keep the supply opening in a continuously opened position so that, depending on the pressure of the supplied air coming from outside, more or less air from the room is recirculated through the supply opening.

A more controllable system can be obtained if the supply opening is also provided with a further valve. The operation of the valve controlling the supply of air from outside and the air entering through the supply opening is preferably common, so that optimum adjustment can easily be obtained by all persons present in the room in which both valves are always in a mutually optimum position. More in particular, according to the present invention, the operation is designed such that upon opening of one valve the other (further) valve is closed and vice versa.

The valves in question can be designed in any way conceivable in the prior art. According to a preferred embodiment of the present invention, one of the valves and more particularly the valve that controls the ambient air in the interior of the room is designed as a butterfly valve. The further valve is preferably designed as a slide valve, wherein a slide can or may not be placed in front of the supply opening. According to a further advantageous embodiment, the gate valve also serves the valve that controls the supply of air from outside. If the valve is a butterfly valve, the closed position can be reached by simply pressing the valve with the help of the slide valve. Automatic opening can be obtained by the presence of a spring or by the imbalance of the butterfly valve. All this can of course also be realized with the help of a rod, cable or the like.

The heat exchanger can comprise a radiator as described above. It preferably comprises a radiator of a water-filled central heating system. The structure can of course also be used if a room needs to be cooled.

The connection of the pipe to the radiator preferably takes place with the aid of a manifold. Such a manifold is preferably of box-shaped design and preferably connects to the underside of the radiator. More in particular, an air-tight connection between manifold and radiator is realized as much as possible, so that the draft or chimney effect described above is optimized. To this end, the walls of the manifold can be adapted to the dimensions of the radiator.

Moreover, the present invention relates to a ventilation system comprising a conduit provided at one end with a valve and at the other end provided with a manifold, wherein a supply opening is provided in said conduit and a further shut-off valve for closing off said supply opening. This ventilation system preferably has the properties described above with reference to the structural construction.

The invention will be explained in more detail below with reference to an exemplary embodiment shown in the drawing. Show:

FIG. 1 schematically a wall of a room; FIG. 2 the ventilation system according to the invention;

FIG. 3 the combination of the ventilation system according to the invention and the departure in a first position of the valves; and

FIG. 4 shows the construction according to FIG. 3 in a second position of the valves.

In Fig. 1, 1 denotes a wall of an architectural construction. As appears from Figs. 3 and 4, this is a partition wall or outside wall between a room 17 and the outside space 18. Wall 1 is provided with a window 2 under which a radiator 3 or other heat exchanger is located. This is preferably a radiator heated or cooled by a central heating system with circulating liquid such as water. The outflow nozzle 16 of a ventilation system 4 is present on the underside of this radiator 3, details of which are apparent from Fig. 2. This outflow nozzle 16 is provided with walls 20 which slide over the underside of the plates of the radiator 3, as can be seen from Figs. 3 and 4, so that only a conduit designed as sleeve 5 is visible here at the underside of the radiator. The outlet nozzle 16 connects to the outflow nozzle 16 which is provided with a supply opening 6. The end of the conduit 5 opens into a valve housing 13 in which a valve 7 and more particularly a butterfly valve is arranged, which is pivotable about axis 21 In addition, in line 5 there is a valve 8 consisting of a slide which can be moved back and forth with the aid of an operating button 14 such as from FIG. 3 and 4. To this end, a slot can be provided in the pipe 5, but it is also possible to provide displacement of the slide 8 without making an opening. Slide 8 consists of a sleeve part 9 (see Figs. 2 and 3) which is provided with a closed front wall 10 at the front side. This front wall 10 has a shape that corresponds to the shape of the feed opening 6 and in the position shown in Figs. . 3, the supply opening 6 can be closed.

On the outside 18 there is a grid 12 in the wall 1. In addition, the opening 19 in the wall 1 is provided with a finishing ring 15.

Like from FIG. 3 and 4, the architectural construction with ventilation system described above works as follows. In the in FIG. 3, the slide 8 (further valve) has been moved to a position where the supply opening 6 is closed. Air originating from outside moves through the grille 12 along opened butterfly valve 7 through tube part 9 to outflow nozzle 16 between the plates of the radiator 3 where this cold air (winter) is heated by the radiator. If the user wants less fresh air supply and more air recirculation in the room, he moves slider 8 to the right with the aid of control button 14 as shown in FIG. 4 through which the supply opening 6 is released. During this displacement the sleeve part 9 presses the butterfly valve 7 into the closed position so that only air from the room is circulated via the radiator. In this way the heating surface of the radiator can always be optimally utilized and the heat transfer between the radiator and passing air is always optimal without producing excessively heated air.

Of course, it is possible to provide a position between that shown in FIG. 3 and 4, that is to say a position in which both a part of the air is recirculated via the supply opening 6 and another part of the air comes from outside. All this can be accurately controlled using the operating button 14 according to the present invention. In addition, an indication may be present on the outside of the line 5 which indicates the operating condition of the position of the control button 14.

The system described above is easy to install and remove. The latter can be important for cleaning work.

After the above, it will be understood that there are numerous possibilities for further implementation of the invention. The valves can for instance be different types of valves which are for instance coupled to each other with a rod mechanism or the like.

These and further variants that are obvious after the above are within the scope of the appended claims. Moreover, rights are explicitly requested for embodiments as described in the subclaims independent of the main claim.
