PROBLEM TO BE SOLVED: To prevent worsening of a feeling due to vibration and noises by reducing the number of starting and stop times of a sub-engine at an intermediate period where an air-conditioning load is low. SOLUTION: A vehicular air conditioner having a cold storage unit is provided with a cold storage unit 20 connected to a refrigerant system 10 through bypass of an expansion valve 14 and an evaporator 15 performs temporary execution of cold storage operation, through which a refrigerant is fed to the cold storage unit 20, and suppresses cooling capacity during cooling operation at an intermediate period during which an air-conditioning load is low and cooling operation and heating operation are alternately repeated. By executing cooling operation by the cold storage unit 20, heating capacity during heating operation is suppressed. |
