Rotational speed control for a scroll compressor

摘要

A scroll compressor wherein a value obtained by multiplying a wrap height by a driving speed is controlled to be within a range of 500 - 1000mmHz at a low speed driving (less than 35Hz). The wrap height of the scroll compressor, and the driving speed are set to be optimum, thereby preventing the scroll compressor from being operated at a speed excessively lower or higher than a predetermined driving speed.
