Abstract
An outdoor unit disposed under a floor of a vehicle and including a compressor and an outdoor heat exchanger serving as a condenser during a cooling operation, an indoor unit disposed at a ceiling portion of the vehicle, including an indoor heat exchanger serving as an evaporator during the cooling operation, and connected to the outdoor unit by refrigerant pipes, and an inverter unit including a cooling heat exchanger serving as an evaporator, an air-conditioning inverter device, and a cooling air-sending device sucking outdoor air for heat exchange by the cooling heat exchanger and cooling the inverter device by cooled air obtained by the heat exchange are provided; and the cooling heat exchanger is connected in parallel to the outdoor unit by refrigerant pipes.
Claims8
A vehicle air-conditioning apparatus comprising:
- an outdoor unit disposed under a floor of a vehicle and including a compressor and an outdoor heat exchanger serving as a condenser during a cooling operation;
- an indoor unit disposed at a ceiling portion of the vehicle, including an indoor heat exchanger serving as an evaporator during the cooling operation, and connected to the outdoor unit via a refrigerant pipe;
- and
- an inverter unit including a cooling heat exchanger serving as an evaporator, an air-conditioning inverter device, and a cooling air-sending device for sucking outdoor air for heat exchange by the cooling heat exchanger and cooling the inverter device by cooled air obtained by the heat exchange, wherein
- the cooling heat exchanger and the indoor heat exchanger being connected in parallel to the outdoor unit by a refrigerant pipe.
