The invention relates to an air-conditioner having two heat-recovery units (10, 12), each of the heat-recovery units (10, 12) being traversed by a first flow channel system (14) and a second flow channel system (16). The heat-recovery units (10, 12) can be optionally operated for recuperative operation as a heat transmitter, and regenerative operation as a heat accumulator. Flap systems (60, 66, 68, 74, 78, 80 or 60', 66', 68', 74', 78', 80') associated with each of the heat-recovery units (10, 12) convey the supply flow (56) of surrounding air and the escaping flow (58) of outgoing air in such a manner that during recuperative operation both fluid streams flow through the heat-recovery units (10, 12), whereas during regenerative operation only one of the fluid streams respectively flows through, alternating in succession with each other, the one heat-recovery unit (10, 12) in each case, thereby achieving optimum use of the air-conditioner in the widest possible range of environmental conditions. |
