Abstract

The ventilation system (2) for a building (1), particularly a dwelling house, involves air fed in and out of the building via a system of channels (9) also involving a fan (4), heat exchanger (5) and/or heating equipment (3). In the ceiling of a room, or in the floor of the room above with specific spacing first recesses or channels are provided in a first direction, mutually connectable by a transversal main channnel, to which all the main apparatus is connectable. At least the channels incorporate an open connection extending to the room for the displaceable fitment of the ventilation devices. The recesses are made of concrete plates created during the moulding of a concrete floor.

Description

VENTILATION SYSTEM AND BUILDING PROVIDED WITH THIS

Thanks to improved insulation and sealing of not only residential buildings but also office buildings, balanced air ventilation in combination with heat recovery is becoming increasingly popular in addition to air conditioning.

U.S. Pat. No. 4,672,887 describes a road handling device in which, among other things, channels are cast into a concrete floor of a building. These channels are herein provided with fixed openings which are suitable for extracting air from the space at suitable fixed places in a space by means of an opening in the concrete.

With the redesign of a building, the 15 air ducts that are installed in standing ducts and behind ceilings, for example, are a major problem. Substantial chopping and breaking work, as well as installation adjustments, must often take place when a building is reclassified.

The present invention provides a ventilation system for a building, in particular a residential building, in which air is supplied and / or discharged into the home via a system of channels and in which equipment such as a fan, a heat exchanger and / or a heat exchanger A heating device is included, wherein in the ceiling of a room, or in the floor of the other room located above that room, first recesses or channels are accommodated at predetermined distances in a first direction, which can be mutually connected by means of main channel extending substantially transversely thereto, and wherein the equipment can be connected to the channels, characterized in that at least the channels comprise an open connection which extends over a substantial part of at least the channel to the space for the movable provision of ventilation means.

Thanks to the ventilation system according to the present invention, inner walls can easily be moved relative to a flat ceiling. A subsequent air duct can then be connected to the ventilation system (or the air-conditioning system) without extensive work on the installation having to take place.

Preferably, recesses are provided in advance in concrete plates, so that the construction work can be carried out quickly and easily. Channels of insulating plastic or metal can then be placed in the recesses, after which the finishing can take place, for example, through a cover cap, stucco or spraying. The equipment can then be connected to the channels, which is advantageous from the viewpoint of efficiency and avoids contamination / damage to the equipment. Moreover, the building can be adapted to user requirements at a late stage without consequences for the construction time. The further layout of the interior space can also be for the account and risk of the user.

The recesses and main channels can be accommodated in a poured concrete floor, in particular with floor systems such as a formwork plate floor, channel plate floor or possibly also in a floor poured in one piece.

In a further preferred embodiment, the main channels are in view below the channels included in the floor, these being to be neatly finished.

Another variant concerns the inclusion of the channels in a lowered ceiling which is arranged at some distance from an existing floor construction.

The present invention furthermore provides a building provided with a system, wherein the main channel is preferably arranged in the poured concrete of the construction floor.

Further advantages, features and details of the present invention will be elucidated with reference to the following description with reference to the accompanying drawings in which:

FIG. 2 is an exploded view of a first preferred embodiment of a ventilation system according to the present invention;

FIG. 3 is a view of a detail of the installation of FIG. 2 in assembled form;

FIG. 4 is an exploded view of another preferred embodiment of a ventilation system according to the present invention;

FIG. 5 is a view of a detail of the system of FIG. 4;

FIG. 6 is a perspective view of a further preferred embodiment of a system according to the present invention;

FIG. 7 is a view of a detail of a preferred embodiment of a system according to the present invention; FIG. 8 is a perspective view of a detail of a system according to the present invention;

FIG. 9 is a sectional view of another detail of another embodiment of a ventilation system according to the present invention. In a manner not shown in Fig. 30, the channel schematically indicated by 9 extends along a floor of the residential building (not shown), as will be apparent from the following.

In a residential building 1 there is a ventilation system 2 which, in a heating device 3, comprises a fan 4, a heat exchanger 5, a supply pipe for outside air 6, and a discharge pipe for hot air 7, as well as a combined channel 9 for supply and discharge of air in resp. from the living room.

In a first preferred embodiment, a number of recesses 12, 13, 14 and 15 are provided in a concrete floor 11 (Fig. 2), in which channel parts 16 and 16, respectively. 17 can be provided which can be finished with cover plates 18. In an embodiment not shown, these can also be flat.

As can be seen from Fig. 3, an air duct 16 can comprise both a portion 19 for hot air and a portion 20 for cold air, in order to allow further heat exchange to take place via intermediate wall 8. The recesses and channel parts 16 are preferably arranged at a regular distance, which can vary from building to building and from space to space and are in each case connected to the channel 17.

In the embodiment according to fig. 4 a lowered ceiling 32 is arranged under a floor 31 which comprises profiled parts 33 in which channel parts 34 are arranged which can correspond to channel parts 16, from fig. 3, and which can be covered in a similar manner with cover plates 35.

In the embodiment according to Fig. 6, concrete elements (wide plates) 41 are placed against each other such that recesses 42 are created in which the channel parts can be placed. The channels can be mutually connected by means of a main channel 43 which is placed over it, after which concrete is poured over it. The recesses are preferably located in the span direction of the pull zone of the poured concrete floor, while the main channel 43 is preferably located in the zero zone in order to avoid forces on and damage to the channels and not to weaken the floor construction. The channel sections are therefore also accessible from the living room.

In the embodiment according to Fig. 7, a channel-forming element 51 is placed between plates 52, so that a recess 53 is created in which a channel part 54 can be provided which can be finished, for example, with the aid of plasterboard 55 and stucco.

Concrete 56 can be poured over the plate 52 and the element 51 in which the main channel can then be accommodated.

It is furthermore important that channels can be connected or closed with each other.

FIG. 8 shows a detail in which a first main channel 81 and a second main channel 82, which are transversely mutually connected, can be connected to each other by means of an (electronically) controllable valve-83 or connecting element which preferably causes little air turbulence and which is switchable between the channels connectable position and the channels not connecting position.

In the embodiment according to Fig. 9, insulation 72 is provided around a channel 71 provided with a metal heat exchanger, while space 77 is also present in a recess 74 for the provision of electrical wiring 75 or central vacuum system. In this situation, use is preferably made of a removable cover 76 so that an electrician or a ventilation installer can still access the work room later.

The present invention is not limited to the above described preferred embodiment thereof; however, the rights sought are defined by the following claims within the scope of which many modifications are conceivable.
