PROBLEM TO BE SOLVED: To provide a vehicular air conditioner with a cold storage heat exchanger system capable of sufficiently securing thermal capacity and not hindering cool-down. SOLUTION: The vehicular air conditioner has at least a heat exchanger for cooling in an air conditioning duct having a blowing out port to an inside of a vehicle. The vehicular air conditioner is composed of a cold storage unit disposed at the downstream side of the air conditioning duct of the heat exchanger for cooling, a cold storage material cooling passage which is provided in the heat exchanger for cooling and performs the heat exchanging with a refrigerant flowing in the heat exchanger for cooling, a connection means for connecting the cold storage unit with the cold storage material cooling passage, and a circulation means disposed on the connection means. The vehicular air conditioner is equipped with the cold storage heat exchanger system for circulating the cold storage material in the cooling storage material cooling passage, the connection means, and the cold storage unit by operating the circulation means.
