摘要

The ventilation and conditioning unit has a feed air duct (26) and outlet air duct (27) which at least along one section (39,39') to form a heat exchanger adjoin each other by means of a heat transferring gastight partitioning wall (28), and to form a sound damper (29,29') the duct walls of the feed air and/or outlet air duct at least along one section are formed from or have sound insulating material (30) and/or sound insulating structures.
