Abstract: The present invention relates to an air conditioning device for an electric vehicle comprising a fluid separator (20) which passes a part of high-temperature and high-pressure refrigerants coming from a compressor (10) compressing a fluid at a constant pressure and separates the fluid into a high-temperature fluid and a low-temperature fluid; a condenser (30) which forcibly supplies heat generated when the fluid coming from the compressor and the fluid separated from the fluid separator pass to the inside of a vehicle by using a first fan (31) in a heating mode; an expansion valve (40) which vaporizes the fluid liquefied from the condenser at low temperature and low pressure; an evaporator (50) which forcibly supplies cool air generated while taking the heat from the outside when the fluid from the expansion valve and the fluid separator (20) to the inside of the vehicle by using a second fan (51) in a cooling mode; a first three-way valve (60) which is formed at one side of the fluid separator (20), supplies the high-temperature fluid separated from the fluid separator (20) to the condenser (30) in the heating mode, and supplies the high-temperature fluid to the compressor (10) in the cooling mode; and a second three-way valve (70) which supplies the low-temperature fluid separated from the other side of the fluid separator (20) to the condenser (30) in the cooling mode and supplies the low-temperature fluid to the expansion valve (40) in the heating mode.
