  • Scroll compressor
    Patent number: 8678774
    Abstract: A scroll compressor is provided. A value obtained by multiplying a wrap height (H) by a driving speed (V) may be controlled to be within a range of approximately 500˜1000 mmHz at a low speed driving (less than approximately 35 Hz). The wrap height of the scroll compressor, and the driving speed may be set to be optimum, thereby preventing the scroll compressor from being operated at a speed excessively lower or higher than a predetermined driving speed. This may allow the scroll compressor to be operated at an optimum low speed corresponding to the wrap height, and thus, the compressor and a refrigerating cycle apparatus having the same may have enhanced performances.
