Air conditioner with inverter

Abstract

Abstract PURPOSE:To attain lower noises of an outdoor fan and a less power consumption of a compressor motor by rotating the motor in proportion to the rotational frequency of the motor with a parallel connection of the compressor motor and the outdoor fan motor. CONSTITUTION:An A.C. power source 16 is converted into a D.C. voltage through a converter section 13. Then, the D.C. voltage is changed to a three- phase A.C. current variable in the frequency through an inverter section 15 and drawn to a compressor motor 20 so as to follow the rotational frequency of the motor 20 according to a load during the operation. In a conditioner with an inverter 12 of such a type, the motor 20 and an outdoor fan motor 21 are connected in parallel to an output terminal of the inverter section 15 to rotate the motor 21 at a rotational frequency proportional to the motor 20. This results in lower noises of the outdoor fan and a less power consumption of the outdoor fan motor 12.
