PROBLEM TO BE SOLVED: To enable continuation of normal operation even when abnormal condition is generated in an operating indoor machine by a method wherein a control device, operating the whole of multi-chamber air conditioners normally by compensating the functions of detecting means or operating means, which can not be operated normally, through the other detecting means or operating means, is provided. SOLUTION: The initial value of amount of operation, such as the driving frequency, the opening degree of an indoor expansion valve and the like, is operated in a control device in accordance with an outdoor air temperature, an indoor air temperature and the like, then, is outputted (S1-S5). An indoor machine air outlet temperature and air temperature of a utilizing house are detected by detectors to operate the capacity of the indoor machine (S8-S9). When an abnormal condition is obtained, newly clarifying of the characteristics of an indoor machine under abnormal condition is prepared (S10-S12). A parameter for indicating the characteristic of the indoor machine is estimated. According to this method, the opening degree of the indoor expansion valve is operated (S13, S14). The driving frequency of a compressor is operated newly and operation effected by prior steps is repeated until the operation of the multi-chamber air conditioner is stopped (S15-S17). |
