Embodiment Construction
[0039] Hereinafter, embodiments will be described in detail with reference to the drawings. In addition, in the following description, the same code|symbol is attached|subjected to the same component.
[0040]
[0041] refer to figure 1 and figure 2 , the structure of the vehicle-mounted temperature adjustment device 100 according to one embodiment will be described. figure 1 It is a configuration diagram schematically showing the vehicle-mounted temperature control device 100 . The on-vehicle temperature control device 100 is configured to include a refrigeration circuit 120 , a low-temperature circuit 130 , and a high-temperature circuit 140 , and the circuits exchange heat with each other. The in-vehicle thermostat 100 heats the interior of the vehicle by dissipating heat from the heater core 145 of the high-temperature circuit 140 in the heating operation mode, and heats the interior of the vehicle interior by absorbing heat from the evaporator 126 in the cooling ope...

The amount of heat generated by an electric motor and the accuracy of output control are appropriately controlled according to the presence or absence of air blowing by an air blowing unit. A vehicle-mounted temperature controller provided with a compressor having a compression part compressing a refrigerant and a drive motor driving the compression part and using waste heat accompanying driving of the compression part to make the temperature of the refrigerant rise, a blower blowing air to a heater core raised in temperature by receiving heat of the refrigerant and blowing air exchanged in heat with the heater core to the inside of the passenger compartment, and an electronic control unit controlling 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 becomes relatively larger to thereby drive the drive motor by an inefficient drive operation when the blower 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 to a change of the current phase becomes relatively smaller to thereby drive the drive motor by an inefficiently drive operation when the blower is in a driven state.
Description
technical field [0001] The present disclosure relates to in-vehicle thermostats. Background technique [0002] Conventionally, as a compressor used in a refrigeration circuit for a refrigerant cycle for an air conditioner, an inverter-motor-integrated compressor configured to integrally accommodate a A compression unit that compresses the refrigerant sucked into the airtight container, an electric motor that drives the compression unit, and a drive circuit that drives the electric motor are configured so that heat-generating components in the electric motor or the drive circuit can be connected to the suction side The refrigerant performs heat exchange, and an on-vehicle temperature control device including such a compressor has been proposed (for example, Patent Document 1). In addition, the on-vehicle temperature control device is provided with a centrifugal fan (air blower) that blows air to the heat exchanger through which the heated refrigerant passes and flows, and bl...
