Abstract
A compression device includes a controller to control an operating speed of a compressor based on a detected level of oil in an oil storage area. During a speed-change operation, the controller controls acceleration of the compressor to maintain the oil level within a predetermined range when the oil level is detected to be outside the predetermined range.
