<p><P>PROBLEM TO BE SOLVED: To provide a ventilation air-conditioning device capable of suppressing acceleration/deceleration vibration generated when starting/stopping a compressor. <P>SOLUTION: As a body of the ventilation air-conditioning device is provided with a refrigerating cycle composed of a single phase induction compressor 1, a condensation coil 2, a pressure reducing means 3 and an evaporation coil 4, and a driving circuit 11 of the single phase induction compressor 1 is provided with a decelerating means 3, rotary torque of the single phase induction compressor 1 can be reduced, and the speed can be reduced by the load, thus the acceleration/deceleration vibration generated in starting/stopping the single phase induction compressor 1 can be reduced, and vibrational stress to refrigerant piping 5 can be reduced. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
