Abstract
A vehicular air conditioner is provided which is capable of heating a vehicle interior with heat of a battery and also preventing deterioration in heating performance due to a decrease in circulating refrigerant. The vehicular air conditioner includes a battery temperature adjustment deviceto circulate a heat medium to thereby adjust the temperature of a batterymounted on a vehicle. The battery temperature adjustment devicehas a refrigerant-heat medium heat exchangerto exchange heat between the refrigerant and the heat medium, and includes a check valveto return the refrigerant flowing out from the refrigerant-heat medium heat exchangerto a suction side of the compressorand to obstruct the flow of the refrigerant flowing out from the refrigerant-heat medium heat exchangerand directed toward an outdoor heat exchangerand a heat absorber
