PURPOSE:To provide an air conditioner in which a suitable amount of refrigerant can be distributed to each indoor unit irrespective of a length of the tube between an outdoor unit and the each indoor unit. CONSTITUTION:Refrigerant pressure Pc2 of a gas side tube of each indoor unit is sensed by each refrigerant pressure sensor 36, refrigerant pressure Ps of a low-pressure side tube of an outdoor unit A is sensed by a refrigerant pressure sensor 24, a tube length between the unit A and each indoor unit is detected from a difference DELTAP between the detected pressure Pc2 and the pressure Pc, and an opening of each flow regulating valve 32 is corrected in response to the detected each tube length.
