Abstract

PURPOSE: To make it possible to temporarily operate an air-conditioning system in an abnormal state, by disposing an interrupting switch between an input signal stage for operating each compressor and a trouble indicating signal stage so as to inturrupt signals therebetween.
CONSTITUTION: When a trouble indicating signal stage 27 transmits a signal to a common control circuit 20 due to an abnormal state of a compressor 38, operation of all system is interrupted. In this state, when a switch 21 is turned off, a signal from the common control circuit 20 to a compressor control circuit 33 is interrupted, and therefore the system is controlled by external sensors which belong to the common control circuit 20 itself. Further, since the signal from the trouble indicating signal stage 27 is also interrupted, it is estimated that no troubles are occured, thereby the compressors other than the abnormal one are normally operated. With this arrangement, an air-conditioning system having a plurality of compressors can be temporarily operated with effect in an abnormal state.
