PROBLEM TO BE SOLVED: To achieve air-conditioning operation suited for an indoor air- conditioning unit for improving comfort even if the form and the development year of the indoor air-conditioning unit differs. SOLUTION: Transmission data transmitted from the indoor unit control section are read (step S21), an operation mode is determined (step S22), it is discriminated whether the number of operation rooms has changed or not (step S24), and the initial frequency of a compressor and the initial opening of a motor-driven expansion valve are determined based on the transmitted, actual capacity value of each indoor air-conditioning unit when the number of operation rooms has changed (step S25). |
