Ventilation unit comprizing a supply and a discharge from and the outside air, as well as a supply and a discharge for the room to be ventilated. The ventilation unit comprises at least a first heat exchanger and a cooling unit, and a second heat exchanger which is connected in the flow direction of the supply air downstream (or upstream) of the first heat exchanger. To the first heat exchanger are connected a primary supply for outside air, and a primary discharge which leads, via the cooling unit, to the secondary supply of the first heat exchanger. The secondary discharge of the first heat exchanger feeds a primary supply of the second heat exchanger, the primary discharge of which is connected to the room supply. The secondary circuit inlet of the second heat exchanger is connected to the room discharge and the outlet is connected to the outside. |
