AIR GUIDING KIT FOR A VENTILATION SYSTEM, AND VENTILATION SYSTEM COMPRISING SUCH AN AIR GUIDING KIT

The invention relates to an air guiding kit (1, 2) for an air ventilation system in which outside air (AL) originating from the surroundings of an apartment or a house is supplied to a plurality of rooms of the apartment or the house as supply air (ZL) via a heat exchanger and in which discharge air (AL) originating from the plurality of rooms of the apartment or the house is discharged into the surroundings of the apartment or the house as exit air (FL) via the heat exchanger. Heat is exchanged between the air of the supplied airflow and the air of the discharged airflow in the heat exchanger. The supply air originating from the heat exchanger is distributed to multiple supply air channels and flows into the plurality of rooms via the supply channels, and the discharge air originating from the plurality of rooms is collected via multiple discharge air channels and flows into the heat exchanger via the discharge air channels. The air guiding kit (1, 2) has a supply air distributor (1) and a discharge air collector (2). The supply air distributor (1) has a first channel section or a supply air distribution channel (1a) for distributing supply air to multiple supply air channels and a second channel section or a supply air transition region (1b) as a transition between the supply air distributor (1) and a supply air connection (3) of the heat exchanger. The discharge air collector (2) has a first channel section or a discharge air collection channel (2a) for collecting discharge air from multiple discharge air channels and a second channel section or a discharge air transition region (2b) as a transition between the discharge air collector (2) and a discharge air connection (4) of the heat exchanger.
