An air-conditioning unit with a recuperative heat exchanger (24), preferably a plate heat exchanger, in which exhaust-air passages (23) are disposed in cross-flow relation to supply-air passages (20) over a portion of the length of the passages, namely at the inlets and outlets of the passages, and in counterflow relation over the remaining portion of the length of the passages. Control of the supply-air temperature is effected by controlled bypassing of the supply air and/or the exhaust air over the heat exchanger (34) by means of dampers (26, 27). |
