Document Type and Number:
Japanese Patent JP2014129095
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle air conditioner and a vehicle capable of preventing oil from entering a condenser and improving a cooling capability and cooling efficiency.SOLUTION: A vehicle air conditioner 60 includes: a compressor 11; a condenser unit 12 that includes a condenser for condensing high-temperature and high-pressure gas refrigerant discharged from the compressor 11 into liquid refrigerant; an expansion valve for decompressing/expanding the refrigerant passing through inside of the expansion valve; and an evaporator unit 14 that includes an evaporator for evaporating and gasifying the low-temperature and low-pressure liquid refrigerant passing through the expansion valve. An oil separator 20 is included in the condenser unit 12 upstream of the condenser. The condenser unit 12 and the evaporator unit 14 are arranged adjacently. An oil return tube 21 connected to the oil separator 20 is arranged in parallel to a refrigerant return tube 23 and then connected to the refrigerant return tube 23.
