PURPOSE: A dual air-cone system for a vehicle is provided to improve the heat performance of a second evaporator by absorbing refrigerant vaporized by a second evaporator. CONSTITUTION: A dual air-cone system for a vehicle comprises a compressor(10), a condenser(20), a first expansion valve(31), a second expansion valve(32), a first evaporator(41), and a second evaporator(42). The compressor compresses the refrigerant of low temperature and low pressure to the refrigerant of high pressure and high temperature. The condenser condenses the refrigerant of high pressure and high temperature into the refrigerant of medium temperature and high-pressure. The first and second expansion valves change the refrigerant of the medium temperature and the high-pressure into the refrigerant of low temperature and low pressure. The first and the second evaporator heat-exchanges the refrigerant passing through the first and the second expansion valve with the air.
