Abstract
A device and method for reducing vibration in a compressor are provided. The device for reducing vibration in a compressor may include a compressor controlled to be operated at a target operating velocity after starting; a power supply that supplies power to the compressor; and a controller that controls the power supply so that a magnitude or a phase of the power supplied to the compressor is changed. The controller may control the power supply so that vibration generated in the compressor is offset by an exciting force generated in the compressor within a predetermined time interval multiple times when the compressor starts or when the compressor stops during a target operation velocity operating of the compressor.
Claims20
A device for reducing vibration in a compressor, comprising:
- a compressor controlled to be operated at a target operating velocity after starting;
- a power supply that supplies power to the compressor;
- and
- a controller that controls the power supply so that a magnitude or a phase of the power supplied to the compressor is changed, wherein the controller controls the power supply so that vibration generated in the compressor is offset by an exciting force generated in the compressor within a predetermined time interval multiple times when the compressor starts or when the compressor stops.
A device for reducing vibration in a compressor, comprising:
- a compressor of a refrigeration cycle and operable at a target operating velocity;
- a power supply that supplies power to the compressor;
- and
- a controller that controls the power supply so that a magnitude or a phase of the power supplied to the compressor is changed, wherein the controller controls the power supply so that the compressor is accelerated or decelerated to a first velocity, which is less than the target operating velocity, when the compressor starts or when the compressor stops.
A method for reducing vibration in a compressor, comprising:
- primarily accelerating a stopped compressor to a first velocity;
- and
- secondarily accelerating the compressor to a target operating velocity, wherein a time as long as approximately half of a period of a natural frequency of compressor vibration has elapsed from a primary acceleration start time of the compressor to a secondary acceleration start time of the compressor.
