摘要： PROBLEM TO BE SOLVED: To provide a compressor control system for efficiently eliminating a liquid phase refrigerant in a compressor.
SOLUTION: In this control system, the lubricating oil temperature of an oil reservoir part inside the compressor 3 and the internal pressure of a refrigerant intake pipe 9 are detected first, or the pressure and temperature of discharge side piping 12 of the compressor are detected. In the case of the former, a control device 10 first assumes the viscosity of lubricating oil from the input lubricating oil temperature in the oil reservoir part of the compressor and intake pipe pressure of the compressor. In the case of the latter, the viscosity of the lubricating oil is assumed from the input discharge side piping pressure and temperature. Whether the viscosity is higher or lower than a predetermined value is determined from the result, and according to the determined result, an electrical command for making the rotating speed of the compressor to the required lowest speed is given to an inverter 11. The above control is terminated when the control device 10 determines that the viscosity of the lubricating oil has returned to the tolerance, to return to normal compressor operation.
