Patent number: 11192428Abstract: A vehicle air-conditioning device is provided which is capable of eliminating or suppressing vibration and noise generated due to the application of a counterpressure to an opening/closing valve. The vehicle air-conditioning device includes a refrigerant circuit R having a compressor 2, a radiator 4 to perform heat exchange between a refrigerant and air, an outdoor heat exchanger 7, a heat absorber 9, and a solenoid valve 40. The compressor 2 and the solenoid valve 40 are controlled to air-condition a vehicle interior. A decompression speed at a refrigerant inflow side of the solenoid valve when the compressor 2 is stopped and the solenoid valve 40 is closed is faster than that at a refrigerant outflow side thereof. When operation is stopped from a state in which the compressor 2 is operating with the solenoid valve 40 being in an opened state, the opened state of the solenoid valve 40 is maintained even after the compressor 2 is stopped.Type: GrantFiled: April 23, 2018Date of Patent: December 7, 2021Assignee: Sanden Automotive Climate Systems CorporationInventors: Ryo Miyakoshi, Megumi Shigeta, Osamu Takazawa, Kohei Yamashita
