To provide an integrated air conditioner enabling an efficient cooling operation by compensating the heat exchanging capacity of an outdoor heat exchanger using part of an indoor heat exchanger as a condenser during a high temperature cooling operation.

During the high temperature cooling operation, a first solenoid valve 7 and a second solenoid valve 8 are opened, a first expansion valve 9 is partially opened, and a second expansion valve 10 is fully opened. Refrigerant circulates through a compressor 1, a third port (c) to a first port (a) of a first four-way valve 1, a third port (g) to a first port (e) of a second four-way valve 3, the outdoor heat exchanger 4, an indoor main heat exchanger 5 and an indoor sub heat exchanger 6, the indoor sub heat exchanger 6, a fourth port (d) to a second port (b) of the first four-way valve 2, the indoor main heat exchanger 5, a fourth port (h) to a second port (f) of the second four-way valve 3, the second port (b) of the first four-way valve 2 and the second port (f) of the second four-way valve 3, and the suction side of the compressor 1. Air duct is changed by an air duct changeover plate 19 so that a first blowing duct 15 is communicated with a delivery port 18 and a second blowing duct 17 is communicated with a jet port 12.
