To effectively control a water hammer noise of a solenoid valve during a vehicle is stopping or traveling at a low speed.

In a refrigerating cycle device for a vehicle circulating coolant to a plurality of evaporators 12, 22 connected in parallel by an electric compressor 31, solenoid valves 19, 29 are connected to a plurality of the evaporators 12, 22 respectively to intermit flow of coolant, the solenoid valves 19, 29 are opened and closed after tentatively dropping rotation speed of the electric compressor 31 by a control device 40 and rotation speed of the electric compressor 31 is dropped to lower rotation speed at low vehicle speed than that at high vehicle speed when the solenoid valves 19, 29 are opened or closed during operation of the electric compressor 31.
