Title:
VEHICLE AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/179594
Kind Code:
A1
Abstract:
The present invention suppresses generation of noise in an electromagnetic valve (30) provided on the inlet side of a radiator (4) and improves durability. A second operation mode is executed that causes refrigerant discharged from a compressor (2) to flow to an outdoor heat exchanger (7) by using a bypass pipe (35), by fully closing an outdoor expansion valve (6), closing the electromagnetic valve (30), and opening an electromagnetic valve (40). After moving to the second operation mode from a first operation mode in which the electromagnetic valve (30) is opened, the electromagnetic valve (40) is closed, and refrigerant is caused to flow to the radiator (4), the controller opens the electromagnetic valve (30) at the timing at which the compressor (2) is stopped.
