    摘要: A control method of an air conditioning system for compressor protection includes, when an air conditioner turn-on request is present, determining, by a controller, whether a compressor operating condition is satisfied from a refrigerant state of an air conditioner, when the compressor operating condition is determined as being satisfied, determining, by the controller, whether the vehicle is in a state of being unattended for a long period of time using information collected from a vehicle, when the vehicle is determined as being in a state of being unattended for a long period of time, performing, by the controller, pre-run control for operating the compressor in a predetermined minimum load condition; and when a pre-run operating time for which the compressor is operated in a minimum load condition reaches a predetermined pre-run holding time, interrupting, by the controller, the pre-run control with respect to the compressor.

    摘要: An electric compressor comprises an electric motor, a filter circuit, a capacitor, an inverter circuit, a drive circuit, a power supply circuit, a switch that connects or disconnects a power supply path that passes power from the power supply circuit to the drive circuit, and a control circuit that controls an operation of the switch. The control circuit connects the power supply path in response to the voltage between the capacitor and the inverter circuit being higher than that between the power supply circuit and the drive circuit, and the control circuit disconnects the power supply path in response to the voltage between the capacitor and the inverter circuit being lower than the voltage between the power supply circuit and the drive circuit.

    摘要: The present disclosure relates to a motor operated compressor, including a housing, a compressor provided in the housing, a motor connected to the compressor to drive the compressor, an inverter coupled to one side of the housing, and connected to the motor unit in an electrically conductive manner. The motor operated compressor includes a hermetic terminal assembly, one side of which extends into the inverter unit, and an opposite side of which extends into the housing. A plurality of busbars have one end of each busbar connected to the opposite side of the hermetic terminal assembly, and the other end of each busbar connected to the motor unit. A first insulating cover portion encloses and seals the hermetic terminal assembly and the plurality of busbars inside the housing, such that a conductive body connecting the motor unit and the inverter unit in the main housing is sealed from refrigerant.

    摘要: An air conditioner for a vehicle includes: a compressor that compresses refrigerant for conditioning air in a vehicle cabin and defines a refrigeration cycle; a detecting section that detects a thermal load of air-conditioning in the vehicle cabin; and a control section that controls a rotational speed of the compressor such that the thermal load detected by the detecting section satisfies a predetermined air conditioning request in the vehicle cabin. In case where the air conditioning request is satisfied by controlling the rotational speed of the compressor, the control section periodically switches between a reference rotational speed and a low rotational speed that is lower than the reference rotational speed in order to maintain a state where the air conditioning request is satisfied. The reference rotational speed is a rotational speed within a predetermined range that includes the rotational speed at which the air conditioning request is satisfied.
