AIR CONDITIONER SYSTEM FOR VEHICLE

摘要

The present invention relates to an air conditioner system for a vehicle, and more specifically, to an air conditioner system including an internal heat exchanger integrated with a receiver drier to be installed between a water cooling type condenser and an expansion valve to divide a refrigerant flowing in from the water cooling type condenser to the expansion valve into a vapor refrigerant and a liquefied refrigerant to be stored and perform heat exchange between the stored refrigerant and refrigerant discharged from an evaporator. The air conditioner system only using the water cooling type condenser or using the water cooling type condenser together with an air cooling type condenser has a structure where a receiver drier and an internal heat exchanger are integrally included, thereby reducing the size of an air conditioner. Furthermore, the refrigerant pipe is simplified and the entire structure of the air conditioner system is also simplified by eliminating the refrigerant pipe additionally mounted on the receiver drier and a connection part, thereby reducing prime costs. Moreover, the air cooling type condenser is added to additionally cool the refrigerant such that the temperature of the refrigerant can be lowered, and performance of the air conditioner can be improved.
