A heat-pump-type air-conditioning device includes an electric compressor, a condenser, a coolant discharge pipe and a muffler. The electric compressor is disposed in a motor compartment of an electric vehicle, while the condenser is disposed in a passenger compartment. The coolant discharge pipe links the electric compressor and the condenser for channeling coolant from the electric compressor to the condenser. The muffler is provided at a position partway along the coolant discharge pipe for suppressing pulsation in the coolant discharged from the electric compressor. The muffler is disposed at a position higher up in the vehicle than the than a coolant discharge port of the electric compressor. A coolant inflow port of the muffler is set at a position higher up in the vehicle than the than a coolant outflow port of the muffler. |
