The present invention relates to an air conditioning system for a vehicle, and more specifically, to an air conditioning system comprising: an air cooled condenser additionally cooling a refrigerant by performing heat exchange between the refrigerant and an air, the refrigerant being positioned between the water cooled condenser and an expansion valve; and a receiver dryer separating a vaporized refrigerant and a liquid refrigerant and storing the liquid refrigerant. Therefore, the sufficiently liquefied refrigerant is introduced into the receiver dryer such that an original function of the receiver dryer is secured, thereby discharging only the liquefied refrigerant into a downstream side of the receiver dryer. Furthermore, a proper amount of the refrigerant, which is suitable for a capacity of the system, can be charged into the system, thereby improving a discharge pressure of a compressor and reducing a consumed power of an air conditioner. Moreover, the air cooled condenser can be used as an overcooled area such that the refrigerant at a further lowered temperature can be introduced into an inner heat exchanger. Therefore, the performance of the air conditioner can be improved, and the temperature of the refrigerant introduced into the compressor can be lower such that the temperature of the refrigerant discharged from the compressor can be prevented from increasing, thereby improving durability and stability of the air conditioning system. |
