PROBLEM TO BE SOLVED: To perform stable rise by a method wherein a first control part to control capacity of a compressor and a second control part to regulate based on the temperature of delivery gas are provided and the control parts are rendered effective, in order. SOLUTION: An indoor machine group 101 is connected to an outdoor machine 100 through connection pipings 28a-28c and connection pipings 29a-29c. After a refrigerant during cooling flows through a compressor 3, a muffler 4, a for-way valve 5, an outdoor heat-exchanger 6, a modulator 8, a strainer 9 and a motor-drive expansion valve 10 for controlling a refrigerant in a main refrigerating circuit, the refrigerant is divided into three circuits. A microcomputer 17 is incorporated in an outdoor machine 100, and receives temperature detecting signals from temperature sensors 18a-18c, 19a-19c, 20, 21, and 22 are received. The outdoor machine 100 is controlled according to a prestored control program. This constitution rapidly increases indoor heating capacity and shortens a rise time. |
