Definitions
- the invention relates to a for the ventilation of Rooms in buildings specific ventilation system with a ventilation unit, the one inlet for supply air and one each room interior inlet for room air and outlet for supply air and / or recirculated room air and substantially flush with the floor in a recess of the floor or a floor slab is, and with a flow direction of the incoming air and / or the circulated room air in front of the room inside outlet arranged heat exchanger.
- the ventilation unit equipped with at least one fan.
- a generic system for decentralized ventilation of Spaces in buildings is previously known from DE 195 48 599 C2.
- This ventilation system comprises a flush with the Floor in a room under a window Recess of a floor slab recorded ventilation unit with a supply air fan, an exhaust fan, a Recirculating air fan and a heat exchanger, optionally with Supply air or circulating air, but also in mixed operation at the same time With supply air and recirculation can be acted upon.
- the climate convector is mounted on a room wall and via a Zubucheinlassö réelle to a central system connected.
- the climate convector has a Air outlet opening and a room air inlet opening. at disconnected central system is one in the climate convector provided change flap due to their weight by the Gravity pivoted into a position at which they the Zu povertyweg closes and the room air path is released.
- the means a fan supplied supply air with simultaneous shut-off of the room interior inlet for room air over the Heat exchangers are passed while being heated, likewise but also when blocking the leading to the heat exchanger Inflow path for supply air above the room interior Inlet incoming room air, which then circulated in the room becomes.
- This measure is of particular importance if the room is cooled when the supply air supply is not active should be prevented.
- the inventive Ventilation system also operated in mixed operation be in which the heat exchanger from supplied Supply air and recirculated room air is swept through.
- this air deflector is in the corner the intersecting inflows and outlets for supply air and circulated Room air to the heat exchanger hinged so that they each in an end position shuts off one of these Zuströmwege and the other inflow path to the heat exchanger releases.
- a further embodiment of the invention can also the front of the room inside outlet for supply air and / or circulated room air arranged first heat exchanger second heat exchanger in inlet flow and fresh air circulation Room air upstream.
- At least the arranged in front of the room interior outlet first heat exchanger generally for tempering the room supplied Air and can accordingly the air flowing through, depending according to desired operation, heat or cool.
- Ventilation unit 10 in a recess 11 a between two floors of a building, that way not is shown extending blanket 12 added.
- the ventilation unit 10, which is designed as a modular insert is stands with feet 13, which is a height adjustment allow on the bottom 14 of the recess 11 and Incidentally, it is flush with the upper edge with a only indicated screed layer 15 or a floor covering 16th built-in.
- the room above the building shell ceiling 12 with the ventilation unit 10 receiving recess 11 is building outside from a storey-high window 18 completed that part a complaint from the shell of the building complaint curtain wall can be.
- the ventilation unit 10 has a building exterior Inlet 20 for supply air, a Zubuchgebläse 21 and a downstream side from the blower 21 in front of a room inside outlet 22 arranged heat exchanger 24. Furthermore, has the Ventilation unit 10 a complained of under the window from the room inside outlet extending inlet 25 for room air, at the one on the downstream side of the Zubuchgebläse 21 on a supply air duct 26 abende flow path 27 for supplying recirculated room air to the Heat exchanger 24 connects.
- Fig. 3 is the before the room inside outlet 22 arranged heat exchanger 24th a second heat exchanger 35 upstream, depending on selected operating mode of supply air, recirculated room air or in mixed operation both supply air and from circulated room air is passed through before the supply air and / or room air through the front of the room inside outlet 22 arranged first heat exchanger 24 passes.
- an outflow ends from the supply air blower forterumblender supply air duct 26 'in front of the second heat exchanger 35 in a Zuströmweg 27 for room air, the directly to the room interior air intake 25 connects. Also in this embodiment serves to control the air flows a louver 30 ', on the side facing the supply air fan in the corner area between the supply air channel 26 'and the flow path 27' is articulated for the room air and, as in the first embodiment, when supply air mode is switched off, the supply air duct 26 'shuts off and with active supply air from the supply air reaches its other end position and thereby the Zuströmweg 27 'for room air or the interior space side Room air inlet 25 closes.
- the ventilation system according to the invention serves the decentralized Ventilation of building spaces.
- the removal of the exhaust air is not the subject of the invention, but can not in here decentralized, under summary several building rooms or centrally done, namely via a lying in the exhaust air flow heat exchanger for at least partial recovery of those contained in the exhaust air Heat energy, which is then used to supply the second Heat exchanger 35 of the ventilation unit 10 is used.
- at least the first heat exchanger 24 also acted upon with cooling medium, in which case the Air supplied to a room can also be cooled.
