<p>PROBLEM TO BE SOLVED: To provide an air conditioning device capable of preventing interphase short-circuit of an AC power source in a case when electrical wirings connecting an outdoor unit and an indoor unit are incorrectly arranged.SOLUTION: An indoor unit 20 is provided with an indoor-side power source circuit 22 to which electric power is supplied from an AC power source 40 to be started, an indoor-side control circuit 23 to which electric power is supplied from the indoor-side power source circuit 22 to be started, and a switch K2R of which ON and OFF are controlled by the indoor-side control circuit. An outdoor unit 10 is provided with an outdoor-side power source circuit 12 to which electric power is supplied from the AC power source 40 when the switch K2R is turned on after starting the indoor-side control circuit 23 to be started. Further detecting means 11a for detecting that any electrical wirings connecting the indoor unit 20 and the outdoor unit 10, are alternately incorrectly arranged, and protecting means for preventing interphase short-circuit of the AC power source 40 in accompany with a turning-on motion of the switch K2R, by limiting start of the indoor-side control circuit 23 when the incorrect wiring arrangement is detected by the detecting means 11a are provided.</p> |
