PURPOSE:To obtain an air-conditioner controller for a vehicle which can continue air-conditioning even when one of a plurality of inverters becomes out of order. CONSTITUTION:The load side of a three-phase AC electromagnetic contactor 6 connected to the load of an inverter 3 for an air blower and the load side of a three-phase AC electromagnetic contactor 7 connected to the load side of an inverter 5 for a compressor are connected to each other through a three- phase electromagnetic contactor 8. In case the inverter 3 failes, air blowing to an indoor air blower 1 and outdoor air blower 2 is continued by using the electric power supplied from the inverter 5 by breaking the contactor 6 and making the contactor 8. |
