Claim 0:
1. A vehicle-mounted temperature controller of a vehicle, comprising:
a compressor having a compression part that drives a refrigerant and a drive motor that drives the compression part and uses waste heat accompanying driving of the drive motor to cause a temperature of the refrigerant to rise,
a blower that blows air to a heat exchanger raised in temperature by receiving heat of the refrigerant and blows air exchanged in heat with the heat exchanger to an inside of a passenger compartment of the vehicle, wherein the blower turns on when the temperature of the refrigerant exceeds a predetermined value, and
an electronic control unit configured to:
control a current phase of the drive motor to a phase by which a ratio of change of an output of the drive motor to a change of the current phase increases to thereby drive the drive motor by an inefficient drive operation when the blower is in a nondriven state and control the current phase to a phase by which the ratio of change of the output of the drive motor to the change of the current phase decreases to thereby drive the drive motor by an inefficient drive operation when the blower is in a driven state.
