PROBLEM TO BE SOLVED: To obtain a multi-room type air conditioner in which each indoor unit can be supplied with an appropriate quantity of refrigerant depending on the capacity thereof and the quantity of refrigerant in a circulation refrigerant circuit can be regulated appropriately depending on the operating state of each indoor unit. SOLUTION: The multi-room type air conditioner comprises an indoor unit 2 comprising indoor side heat exchangers 9, 10, 11 having different heat exchanging capacity coupled with electronic expansion valves 12a, 12b, 12c, a refrigerant distribution unit 3, and an outdoor unit 1 comprising a compressor 4 and an accumulator 5 provided, on the suction and delivery sides thereof, with pressure sensors 33b, 33a and a thermister 34, outdoor side heat exchangers 6, 7, 8 provided, in front and rear thereof, with an electronic expansion valve and a solenoid valve and set, respectively, with heat exchanging capacity corresponding to those of the indoor side heat exchangers 9, 10, 11. The quantity of refrigerant in the refrigerant circuit is regulated lower than the measurements of the pressure sensors 33b, 33a and the thermister 34. |
