摘要

The device has a fresh air blower (4) for exactly reguiding fresh air (1) into an area, in which an exhaust hood (2) is installed, when a blower (12) of the exhaust hood delivers the fresh air outward as exhaust air (9). The fresh air blower extracts the heat in the exhaust air using a heat exchanger (7). A control device is operated by flowmeters of the exhaust air and the fresh air, where the control device regulates the fresh air supply to a volume equal to the exhaust air.
