Abstract
PURPOSE: To improve safety and reliability by stopping a drive of an inverter when a means for detecting the state of the inverter detects a fault, further shutting off a compressor to detect via a wire wound resistor, and informing the effect if the detection results in a fault. CONSTITUTION: At the time of operating, a controller 40 turns ON contactors 41, 42, detects an air conditioning load in response to a detected pressure of a pressure sensor 6, controls an output frequency F of an inverter 30 in response to the load, and inverter drives a compressor 1. At this time, the controller 40 detects the state of the inverter 30 by a current sensor 51 and a voltage sensor 52. When an excess current flows or a voltage drop occurs, the controller 40 decides a fault to stop the drive of the inverter 30, further turns OFF the contactor 42 to shut OFF a compressor motor 1M from the inverter 30. A wire wound resistor of the motor 1M is detected by a wire wound resistor detector 55. If a fault is detected, a fault lamp of a display 44 is lit to inform the fault.
