Abstract
PURPOSE: To improve the reliability of this compressor, by preventing the shortage of lubricating oil by the discharge of the lubricating oil with a refrigerant by mounting a controller for controlling the number of revolution of a motor at a low speed when the lubricating oil produces a bubbling phenomenon by the refrigerant.
CONSTITUTION: The vibration of lubricating oil 17 becomes stronger the higher the number of revolution of a compressor is, and a bubbling phenomenon also becomes violent. If a flow rate of a refrigerant is fast when the bubbling phenomenon is yielded, a large quantity of lubricating oil 17 is discharged with the refrigerant, but the bubbling phenomenon is input to speed signals E by means of a protective circuit portion G as the output of a bubbling detecting machine 16, and the number of revolution of the compressor 15 is lowered. Consequently, the vibration of the lubricating oil 17 falls, the flow rate of the refrigerant becomes lower, the quantity of the lubricating oil held up diminishes, the discharge of the lubricating oil 17 from a discharge pipe 14 is prevented, and the lubricating oil 17 in a sealed housing 13 is not insufficient, thus improving the reliability of the compressor.
