To provide a vehicular air conditioner for easily and efficiently recovering a refrigerant, without largely changing a system, while recovering the refrigerant for minimizing leakage of the refrigerant, when using a combustible refrigerant as the refrigerant of a vapor compression type refrigerating cycle.
This vehicular air conditioner has the vapor compression type refrigerating cycle having a gas-liquid separator by using the combustible refrigerant; and is provided with a vessel communicable with the gas-liquid separator and capable of recovering the combustible refrigerant in the refrigerating cycle by the communication. The vehicular air conditioner is characterized by arranging an opening-closing valve capable of controlling the communication by a signal from an external part in the refrigerant recovery vessel.
