<p>PURPOSE: An air conditioning system for a vehicle is provided to increase the efficiency of a cycle by exchanging heat between refrigerant and cooling water. CONSTITUTION: A compressor(100) compresses gaseous refrigerant. An indoor heat exchanger for cooling(202) cools air in a cooling mode, and reduces humidity of air in dehumidification heating mode. An outdoor heat exchanger(400) cools a refrigerant of high temperature and pressure. Another indoor heat exchanger for heating(200) heats air while cooling the refrigerant of high temperature and pressure in a heating mode. An inner heat exchanger(404) exchanges heat between the refrigerant of high temperature and pressure and another refrigerant of low temperature and pressure to improve the performance of a cycle. An accumulator(600) sends only gaseous refrigerant to the compressor. A cooling apparatus(500) cools a driving apparatus(520) for driving a vehicle. A heat exchanger(402) exchanges heat between cooling water circulating on the cooling apparatus and the refrigerant. Control units(B1,B2,B3) selectively convert first and second refrigerant circulation paths.</p> |
