Abstract

An air conditioning system for a vehicle is provided with: an air conditioning device having a main air blower, a main duct, and a heat exchange section, the air conditioning device converting air, which is sucked into the main duct by the main air blower, into air conditioning air by the heat exchange section and blowing the air conditioning air into the vehicle interior; a suction opening disposed in the vicinity of an occupant's seat; and a sub-duct having one end connected to the suction opening and sucking air from the suction opening. The air conditioning device sucks the air, which is sucked into the sub-duct, into the main duct and blows the air again into the vehicle interior. In the air conditioning system, the air conditioning air blown into the vehicle interior by the air conditioning device is sucked from the suction opening disposed in the vicinity of the occupant's seat. This causes the air conditioning air to be collected and at the same time the air conditioning air flowing rearward beyond the suction opening to be reduced, and as a result, comfortable zone air conditioning can be performed. In a zone air conditioning mode, air conditioning air having a desired temperature is generated by the heat exchange section. This means that the installation of a heat exchange section exclusive for the zone air conditioning is not essential, and as a result, the system can be simplified and the cost can be reduced.

Description

technical field [0001] The present invention relates to an air-conditioning system for a vehicle [an air-condition system for a vehicle] capable of performing zoned air-conditioning (personal air-conditioning) using a part of the vehicle cabin (for example, around passengers) as an air-conditioned area. Background technique [0002] As an air-conditioning system for a vehicle, a zoned air-conditioning system has been proposed that does not air-condition the entire vehicle compartment, but air-conditions only the surroundings of passengers. Patent Document 1 below discloses a conventional zoned air conditioning system. Such as Figure 15 As shown, the vehicle air conditioning system 100 disclosed in Patent Document 1 includes a suction port 102 opened on the upper surface of the seat cushion 101a of the seat 101, and a suction port opened above the headrest 101c of the seat 101. The air outlet [blow-out port] 103, and the channel 104 that connects the suction port 102 and th...
