<p><P>PROBLEM TO BE SOLVED: To provide an air-conditioner for a vehicle which improves a heat radiation performance of a radiator by making an effective use of condensate, and which reduces the power of a compressor through prevention of an pressure increase on the high-pressure side. <P>SOLUTION: The air-conditioner for the vehicle is provided with: the compressor for compressing a refrigerant; the radiator for dissipating a high-temperature high-pressure refrigerant; an internal heat exchanger; an expansion mechanism; an evaporator; and a vapor-liquid separator. The internal heat exchanger performs heat exchange between a low-temperature high-pressure refrigerant and a refrigerant on the low-pressure side, and the vapor-liquid separator separates a low-pressure refrigerant coming out of the evaporator into a gas and a liquid. The air-conditioner for the vehicle has a vapor-compression-type refrigeration cycle which is formed by connecting them one by one, and the condensate generated from the evaporator or from the vapor-liquid separator, or from both of them, is discharged to the radiator. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
