Title:
VEHICLE AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2013/187433
Kind Code:
A1
Abstract:
Provided is a vehicle air conditioner which, by preventing decreases in the discharge rate of coolant from the compressor in low outdoor temperature environments, can obtain the heating capacity needed during heating operation, and can dehumidify without decreasing the heating capacity during dehumidifying heating operation. This vehicle air conditioner is provided with a heat dissipating refrigerant expansion valve (25) that decompresses the refrigerant exiting a radiator (15) in heating operation and first dehumidifying heating operation; a gas-liquid separator (29) which, by inputting the coolant decompressed in the heat dissipating refrigerant expansion valve (25), separates said coolant into a gaseous coolant and a liquid coolant; and a coolant flow path (20k) as a bypass circuit allowing at least a part of the gaseous coolant separated in the gas-liquid separator (29) to enter the portion of the compressor (21) where coolant undergoing compression circulates.
