    • PROBLEM TO BE SOLVED: To provide a multi-chamber type air conditioner in which capacity can be controlled so as to meet load regardless of high or low load by a simple constitution and control and a highly efficient operation having no excessive deficiency in capacity can be done within a wide load range. SOLUTION: According to the provision of start and stop control means 37 of a plurality of compressors, when the total load of indoor machines 29a, 29b, 29c, and 29d is larger than the set value of a high load side, a constant rate compressor 20 with small capacity is started or stopped and a constant rate compressor 21 with large capacity is continuously operated. When the total load is located between the set value of the high load side and the set value of a low load side, the constant rate compressor 20 with small capacity and the constant rate compressor 21 with large capacity are alternately started and stopped. Further, a controller 37 for starting/stopping compressor is provided, and when the total load is smaller than the set value of the low load side, the constant rate compressor 20 with small capacity is stated or stopped and the constant rate compressor 21 with large capacity is stopped.
