Abstract
(EN)
This air conditioner (10) is provided with: an AC-DC converting device (41) that converts a three-phase alternating current supplied from a three-phase AC power source (50) into a direct current; a transistor module (37) that converts the converted direct current into a pseudo-three-phase alternating current; a compressor motor (38) to which the pseudo-three-phase alternating current is supplied; phase-discriminating current detecting devices (39, 40) that detect the quasi-three-phase alternating current to be supplied to the compressor motor (38); an AC detecting device (32) that detects the alternating current of a first phase of the three-phase AC power source (50); an AC detecting device (33) that detects the alternating current of a second phase of the three-phase AC power source (50); and a control device (31) that determines an open phase of the three-phase AC power source (50) on the basis of the detection results of the phase-discriminating current detecting devices (39, 40) and the detection results of the AC detecting devices (32, 33).
