<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of continuing operation until functions of an electric current detector are recovered by repair etc. even if the electric current detector is broken. <P>SOLUTION: At normal time, a control device 9 changes the frequency and voltage of A.C. current output from an inverter device 5 based on an output signal of the electric current detector 7. The changed A.C. current is input to an electric motor 4 for an air blower 2 and wind of set air quantity is emitted from the air blower 2. When determining that the electric current detector 7 is abnormal, the control device 9 continues the operation of the air conditioner 1 by switching to air quantity control based on an output signal of a wind speed detector 8. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
