<p><P>PROBLEM TO BE SOLVED: To improve the performance of cooling, heating and dehumidifying operations by reducing a coolant flow pressure drop at each interior heat exchanger in the cooling, heating and dehumidifying operations by coolant passages in two or more systems in an air conditioner. <P>SOLUTION: In this air conditioner, a compressor 1, an exterior heat exchanger 3, a first interior heat exchanger 6a, a dehumidifying restrictor 46 and a second interior heat exchanger 6b are connected in this order in the dehumidifying operation, and the compressor 1, the exterior heat exchanger 3, the first interior heat exchanger 6a and the second interior heat exchanger 6b are connected in this order in the cooling operation, and the compressor 1, the second interior heat exchanger 6b, the first interior heat exchanger 6a and the exterior heat exchanger 3 are connected in this order in the heating operation. Each coolant passage of the first interior heat exchanger 6a and the second interior heat exchanger 6b is constituted in the divided state into two or more systems. The dehumidifying restrictor 46 is connected between a confluence of the coolant passages of the first interior heat exchanger 6a and a branching point of the coolant passages of the second interior heat exchanger 6b. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
