ABSTRACT:
An air-conditioning device having a common housing case in which there are a heat exchanger through which used air and fresh air can flow formed with plate-shaped heat-exchanger walls which are made of aluminum foil, as well as a fresh-air blower and a spent-air blower. The interior of the housing case is divided into a fresh-air passage leading through the heat exchanger and a spent-air passage leading through the heat exchanger by the stack of foils of the heat exchanger together with internal partitions in the interior of the housing; the housing partitions comprise a controllable by-pass damper through which the spent-air entry side of the heat exchanger can be connected directly to its spent-air outlet side, and comprise a controllable recirculated-air damper through which the spent-air entry side of the heat exchanger can be connected directly to its fresh-air outlet side, the fresh-air inlet and the exhaust-air outlet of the housing case being constructed so as to be able to be shut off. The lower side of the housing case comprises a base which can be sealingly placed on a roof aperture and which jointly possesses an inlet to the spent-air passage and an outlet to the fresh-air outlet comprising a projection nozzle which concentrates the stream of fresh air which is blown out.
