An air-conditioning device includes: a frost formation determination unit configured to determine a frost risk state of an outdoor hot exchanger based on an accumulated time wherein a difference between a temperature detected by an outdoor air temperature detector and a temperature detected by a coolant temperature detector is the same or greater than a frost temperature difference; and an operation control unit configured to control a compressor and a blower so that air led into the cabin reaches a target blowout temperature set based on a required heating performance, and to execute a regular heating operation. In the event of the frost formation determination unit determining the frost risk state, the operation control unit is configured to execute a frost suppression operation wherein the air flow amount by the blower is increased while the target blowout temperature is decreased in comparison with the regular heating operation.

There is disclosed a vehicular air-conditioning device of a so-called heat pump system which eliminates or decreases noise generated when an opening/closing valve opens at a changing time of an operation mode. The vehicular air-conditioning device executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, decompress the refrigerant by which heat has been radiated, and then let the refrigerant absorb heat in an outdoor heat exchanger 7, and a dehumidifying and heating mode to open a solenoid valve 22 in a state of the heating mode, decompress at least a part of the refrigerant flowing out from the radiator and then let the refrigerant absorb heat in a heat absorber 9. When the heating mode changes to the dehumidifying and heating mode, the controller decreases a radiator pressure or a pressure difference before and after the solenoid valve to a predetermined value or less, and then opens the solenoid valve 22.
