Abstract
An air-conditioning device for a vehicle comprising in a housing (13) a first conduit (20) for transmitting a cool air flow (F1) and a second conduit (22), wherein is installed a heat exchanger (24) for transmitting a warm air flow (F2). The conduits (20, 22) are interposed between an air intake (14) and a mixing zone (31) delivering mixed air. A system splitting (40) the air flows (F1, F2), delivered by the conduits (20, 22) is provided at the junction of the two conduits and in the second conduit (22) downstream of the heat exchanger (24). The splitting system (40) comprises transversely alternating a plurality of cool air passages (46) and a plurality of warm air passages (49). The passages emerge into two separate mixing zones (31, 25).
Claims15
A device for heating, ventilating and/or air-conditioning the passenger compartment of a motor vehicle, comprising:
- in a casing (13), a first duct (20) for transmitting a cold-air flow (F1) and a second duct (22) for transmitting a hot-air flow (F2), wherein a heat exchanger (24) is installed in said second duct, said first and second ducts being interposed between an air inlet (14) and at least one mixing region (31) delivering mixed air, and
- an airflow-divider system (40) which shares out the cold-air flow (F1) delivered by the first duct (20) and the hot-air flow (F2) delivered by the second duct (22) into a number of secondary flows, said divider system including, transversely and alternately, a plurality of cold-air passages (46) having their inlets (45) in the first duct (20) and a plurality of hot-air passages (49) having their inlets (48) in the second duct (22),
- wherein said cold-air and hot-air passages (46, 49) define a first series of outlets (50) alternately delivering cold air and hot air into a first mixing region (31) and a second series of outlets (51) alternately delivering hot air and cold air into a second mixing region (25).
