PROBLEM TO BE SOLVED: To provide a vehicular air conditioner having a high performance coefficient even when a thermal load is not high and capable of contributing to power saving in a refrigeration cycle including an inner heat exchanger, a vehicle including the same and a control method for the vehicular air conditioner.SOLUTION: A vehicular air conditioner 100 is mounted to a vehicle. The vehicular air conditioner includes: a refrigeration cycle 1a having a refrigerant circuit 50 that is formed by interconnecting by piping 61-66 a compressor 2, a condenser 3, an expansion device 4 and an evaporator 5 to circulate a refrigerant and an inner heat exchanger 10 for exchanging heat of a refrigerant between a first heat exchange section 11 in which the refrigerant guided from condenser 3 to the expansion device 4 flows and a second heat exchange section 12 in which the refrigerant guided from the evaporator 5 to the suction side of the compressor 2 flows; an outside air temperature sensor 41 for detecting an outside air temperature of the vehicle; a heat radiation amount adjustment device 7 for adjusting the heat radiation amount of the refrigerant of which heat is radiated by the condenser 3; and a processing device 150 for controlling the heat radiation amount adjustment device 7 on the basis of a value of the outside air temperature.SELECTED DRAWING: Figure 1
