<P>PROBLEM TO BE SOLVED: To feed cold air into a vehicle interior with a simple structure even during engine stop, in a vehicular air conditioner. <P>SOLUTION: In a casing 30 of this vehicular air conditioner 16, a heat exchanger unit 34 integrally formed with an evaporator part 50 capable of cooling air and a heater core part 52 capable of heating the air is arranged. A cooling water drawing port 68 for discharging cooling water having circulated in the inside is formed in the heater core part 52, and a flow rate control mechanism 28 capable of controlling the flow rate of the cooling water is arranged in second piping 26 connected to the cooling water drawing port 68. When storing cold in the heater core part 52, flow of the cooling water is shut off in the flow rate adjustment mechanism 28, and a cold storage body cooled by making air cooled by passing through an evaporator part 50 strike against cooling water remaining in the heater core part 52 is produced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
