PURPOSE: To control noise propagated in each power transmission line of the power supply line to control the fluctuation of noise on each line. CONSTITUTION: The power supply line 60 consisting of three wires 6R, 6S, 6T is provided. The power supply line 60 is connected with a compressor motor 22 to which the power is supplied via a power controller 40. Three lines 6R, 6S, 6T are arranged in the triangular shape of the equal line-to-line distance D and connected with each other. Moreover, a power controller 40 is provided with a power converting circuit 50 having an inverter 53. Moreover, the power controller 40 is connected with the power supply line 60 and also provided with a noise filter 41 for removing noise which is generated from an inverter 53 and is then propagated to the power supply line 60. |
