<p>PROBLEM TO BE SOLVED: To provide a multizone cooling and heating air conditioner for not only suppressing frosting unevenly on a heat transfer tube but also preventing excess frosting by maintaining a pressure drop of refrigerant passing a first outdoor heat exchanger constantly. SOLUTION: In the air conditioner comprising a first compressor 1, a second compressor 3, at least one indoor heat exchanger 11 coupled to the compressor 1, at least one second indoor heat exchanger 13 coupled to the second compressor and a single outdoor heat exchanger 9 having a first heat transfer tube for coupling the compressor 1 to the exchanger 11 and a second heat transfer tube for coupling the compressor 3 to the exchanger 13; the exchanger 9 has a first outdoor heat exchanger 5 having a plurality of stripe-like laminated fins partitioned from each other in a length direction of the fins and attached with a first heat transfer tube, and a second outdoor heat exchanger 7 attached with a second heat transfer tube.</p> |
