AIR CONDITIONING SYSTEM FOR A VEHICLE, CAPABLE OF OBTAINING EXCELLENT HEATING PERFORMANCE IN AN EARLY DRIVING STAGE AT LOW OUTDOOR TEMPERATURE

摘要

PURPOSE: An air conditioning system for a vehicle is provided to prevent fogging while obtaining high heating performance regardless of whether a vehicle driving step in a winter season is in an early stage or not.;CONSTITUTION: An air conditioning system(100) for a vehicle comprises a cooling water circulation line(W) and a refrigerant circulation line(R). A compressor(110), a heat exchanger(112), an expanding valve(114), and a first indoor heat exchanger(116) are formed in the refrigerant circulation line. The heat exchanger is for a heat exchange between engine cooling water and refrigerant. The first indoor heat exchanger is for the heat exchange between air flowing into the inside of a vehicle and the refrigerant. An engine, a pump, and a second indoor heat exchanger of the vehicle are formed in the cooling water circulation line. The second indoor heat exchanger is for the heat exchange between the air flowing into the inside of the vehicle and the engine cooling water.;COPYRIGHT KIPO 2013
