Abstract:

The purpose of the invention is to prevent backflow of the coolant from a pulsation suppression means to an electric compressor when the compressor is stopped, while setting the pulsation suppression means at a position above the electric compressor. A heat-pump-type air-conditioning device, provided with coolant discharge pipes (31, 32) linking an electric compressor (10) disposed in the motor room (M) of an electric automobile (1) and a condenser (25) disposed in the vehicle compartment (R) to each other, the coolant discharge pipes (31, 32) channeling the coolant from the electric compressor (10) to the condenser (25). In the heat-pump-type air-conditioning device, a muffler (11) for suppressing the pulsation of the coolant discharged from the electric compressor (10) is provided at a position partway along the coolant discharge pipes (31, 32), and the muffler (11) is disposed at a position further above, with respect to the vehicle, the coolant discharge port (10b) of the electric compressor (10). The coolant inlet (11a) of the muffler (11) is set at a position further above, with respect to the vehicle, the coolant outlet (11b) of the muffler (11).
