A device for the ventilation of rooms consists of an elongate box-like housing 1 with flow ducts 4, 5 for a countercurrent heat exchanger which are formed by parallel partitions 3 and run in the housing longitudinal direction, and with two blowers 6 and 7, arranged in the housing 1, on the one hand for the spent air and on the other hand for the supply air. In order to ensure a low- noise design, the two blowers 6, 7 designed as radial compressors are arranged one behind the other in the housing longitudinal direction respectively on the supply- air inlet side and the spent-air outlet side of the flow ducts 4, 5 and are connected to the flow ducts 4, 5 via two housing chambers 11, 12 lined up next to one another. <IMAGE> |
