AIR CONDITIONER SYSTEM FOR VEHICLE

摘要

The present invention relates to an air conditioner system for a vehicle. The air conditioner system comprises an air-cooled type condenser installed on the coolant circulation path between a water-cooled type condenser and an expansion valve to exchange the heat of the coolant with air, allowing the reuse of the air which has passed through the air-cooled type condenser for cooling the water-cooled type condenser, and improving air conditioning performance and increasing fuel efficiency by reducing power consumption in the compressor. The present invention improves the mounting properties of the air conditioner system in a vehicle engine room using a structure wherein the air-cooled type condenser is arranged in front of the water-cooled type condenser; and provides sufficient cooling performance even in case of a lack of inflow air like an idling condition by placing a blower fan in front of the air-cooled type condenser or between the air-cooled type condenser and the water-cooled type condenser to allow sufficient air inflow. Additionally, the present invention provides a function of a receiver drier by allowing fully liquefied coolant to flow in by installing the air-cooled type condenser; and improves the air conditioning performance by allowing the air-cooled type condenser to be used as a supercooling region.
