Abstract
A vehicle-mounted temperature controller 100 provided with a compressor 2 having a compression part 2a compressing a refrigerant and a drive motor 2b driving the compression part 2a and using waste heat accompanying driving of the compression part 2a to make the temperature of the refrigerant rise, a blower 61 blowing air to a heater core 145 raised in temperature by receiving heat of the refrigerant and blowing air exchanged in heat with the heater core 145 to the inside of the passenger compartment, and an electronic control unit 51 controlling a current phase of the drive motor 2b to a phase by which a ratio of change of an output of the drive motor 2b to a change of the current phase becomes relatively larger to thereby drive the drive motor 2b by an inefficient drive operation when the blower 61 is in a nondriven state and controlling the current phase to a phase by which a ratio of change of an output of the drive motor 2b to a change of the current phase becomes relatively smaller to thereby drive the drive motor 2b by an inefficiently drive operation when the blower 61 is in a driven state.
