|1. (WO2017150735) AIR CONDITIONER FOR VEHICLES|
|Applicants:||SANDEN AUTOMOTIVE CLIMATE SYSTEMS CORPORATION
|Title:||AIR CONDITIONER FOR VEHICLES|
Provided is an air conditioner for vehicles, which is capable of protecting a compressor by detecting the leakage of a refrigerant over time as early as possible. The present invention is provided with: a compressor 2; a heat radiator 4 that radiates heat from the refrigerant; an outdoor heat exchanger 7 provided outside a vehicle room; and an accumulator 12 connected to the refrigerant suction side of the compressor. The refrigerant discharged from the compressor is subjected to heat radiation by the heat radiator to warm the inside of the vehicle room, and the heat is absorbed by the outdoor heat exchanger. A controller detects the amount of a liquid refrigerant inside the accumulator, and determines the occurrence of refrigerant leakage on the basis of the amount of the liquid refrigerant.
