Description

The invention relates to a ventilation beam array arranged in the room according to the preamble of claim 1.

Existing centralized ventilation systems are almost invariably based on the fact that all the air entering and leaving the building is routed through the same ventilation unit. This results in a relatively complicated duct system through which air is forced through the fans. The structure is also tilted by the fact that external supply air ducts have to be insulated10, for example with rock wool, to control condensation water damage. The complex multi-part damper construction is expensive and requires energy-intensive fans to overcome the air resistance.

Another disadvantage associated with centralized ventilation systems is that the ventilation device is designed to be as compact as possible, housed in the smallest possible space, inside the cubic outer casing (housing), which includes filters and fans with its own housing and a disk pack.

The baffle body is surrounded by air baffles and is surrounded by the actual outer body (housing). Ventilation device housings are standardized and consist of a plurality of sheet metal parts sealed with high levels of silicone and various gaskets. The ventilation units are as small as possible, which is why the size of the heat exchangers entering them should be as small as possible. In practice, this means that as much heat-conducting plate surface as possible must be obtained in the smallest possible space, but without the air flow resistances becoming too high. A critical factor in the efficiency of heat recovery is the surface area of the metal plates inside the heat exchanger through which heat is transferred. Another factor affecting the good quality of the heat exchanger is how straightforward the air is to flow within the heat exchanger so that as much of the heated air as possible is in contact with the metal surface as long as possible. The difficulty is that the small size of the heat exchanger results in high air velocity in narrow lamellar structures, which reduces the heat transfer times.

20160234 prh 20 -03- 2019

There are thus many problems with such a centralized ventilation system:

It is difficult to increase the efficiency of the ventilation system with a compact ventilation unit as it would require increasing the surface area of the plate heat exchanger plates, whereby the outer body (housing) itself would have to be expanded. Because of the size of the enclosures 5, lifting the plate area requires re-dimensioning and redesigning the entire ventilation unit to fit the new enclosure size.

The casing (outer casing) is usually built by a subcontractor, whereby the casing structure does not take into account its effects on the design of the plate heat exchanger (ventilation unit), but the ventilation unit is dimensioned according to the casing conditions. Generally, the housing 10 is intended to be made as thermally sealed and compact as possible.

This type of enclosure requires efficient fans and makes the design of the ventilation unit complicated and expensive:

- The structure around the ventilator is complex as it comprises the outer casing, inner casing and air baffles. A large number of joints to be sealed are formed in such a structure.

The prior art plate heat exchangers are provided with a large heat exchange area in a small space, whereby the air velocity between the plates must be increased in order to obtain a sufficiently high heat exchange capacity of the plate heat exchanger. This requires high-power fans when air has to be pushed through narrow structures.

- Existing plate heat exchangers of the current type are often difficult to install on the midsole of terraced houses due to their (cubic) shape.

The foregoing prior art and the problems noted therein, as a starting point, was the first object of the invention to provide a decentralized, apartment-specific I / O unit, which would have significantly lower investment and operating costs than A / C ventilation systems.

Another main goal was to provide an apartment-specific ventilation unit, where the power control of the ventilation unit would be simple and the structure of the ventilation unit housing could be easily modified depending on the location.

The foregoing objects are achieved by the ventilation beam according to claim 1 arranged in the room and by the ventilation beam array according to claim 13.

In this case, the ventilation beam array further comprises one beam line longitudinal air transfer housing for the dirty air flow and one beam line longitudinal air transfer housing for the fresh air air flow housing to divide the 20 air fresh air flow rate for each air flow.

In the invention, the ventilation beam further comprises a cover having a top portion of the deck and a lower portion of the deck viewed from the ventilation beam body and a top portion of the ventilation beam covering the ventilation beam through the opening in the bottom and fresh air is arranged to enter the room from the gap between the lower part of the deck and the ceiling or the lower part of the deck and the wall.

In addition, at least one air filter for removing dirt particles from the air flow and at least one fan for controlling the inlet and outlet streams of dirty air and fresh air to and from the heat exchanger are operatively connected to the vent beam.

The closest prior art to the ventilation beam array according to the invention is disclosed in DE 102006010553. From this patent document, a ventilation device is known which is provided with a heat exchanger 10 through which a fresh air supply and a dirty air outlet can be conducted. However, this patent document does not disclose a replacement beam string where dirty air enters the ventilation beam through an opening in the bottom and fresh air enters the room from a gap between the lower part of the deck and the ceiling or lower part of the deck and the wall.

In a preferred embodiment of the invention, a plurality of housings are provided between the ventilation beam cover and the bottom, each bounded on the one hand by the cover and the base and on the other side walls transverse to the cover and bottom plane; providing at least one longitudinal beam housing for the heat exchanger and at least one longitudinal air transfer housing for dirty air and / or fresh air flow, wherein the first longitudinal lateral wall of each air transfer housing is the same longitudinal sidewall or lateral sidewall with an air gap between them.

Preferably, one bar longitudinal housing for the heat exchanger, one bar longitudinal air transfer housing for dirty air flow and one air transfer housing for fresh air flow are provided inside the ventilation beam, so that each air transfer housing is limited to one longitudinal and longitudinal direction of heat. The air transfer boxes extend longitudinally of the ventilation beam from one end housing to another or from the end housing to the access wall of the ventilation beam.

20160234 prh 20 -03- 2019

The invention is based on the provision of a relatively flat or thin ventilation beam in the room space, within which a heat exchanger, such as a plate or pipe heat exchanger, is located. In addition, fans and filters are provided inside the ventilation beam for directing and purifying fresh air and clean air inlet and outlet streams. In this way, a simple and cost-effective ventilation unit can be installed in the room.
