Abstract
There is disclosed a vehicle air conditioning device which inhibits generation of noise in a solenoid valvedisposed on an inlet side of a radiatorand improves durability of the solenoid valve. A second operation mode is executed to shut off an outdoor expansion valve, close the solenoid valve, open a solenoid valveand thereby send a refrigerant discharged from a compressorthrough a bypass pipeto an outdoor heat exchanger. When a first operation mode to open the solenoid valveand close the solenoid valveand thereby send the refrigerant to the radiatoris shifted to the second operation mode, a controller opens the solenoid valveat a timing to stop the compressor
