摘要： An instantaneous current and instantaneous voltage of a three-phase coil of a brushless DC motor are detected, and the internal condition of a compressor is predicted from these detection values. The prediction about the internal condition of the compressor is made in such a way that motor driving torque which is a parameter of a motor model is identified and poor lubrication, liquid compression or the like is predicted from this identified motor driving torque. This enables it to make, in real time, a failure forecast, failure diagnosis etc. on the compressor.

摘要： A high pressure chamber in a casing communicates at the bottom thereof with a liquid retainer. A communication pipe is connected at one end thereof to the upper end of the liquid retainer and connected at the other end thereof to an intake pipe. A gas container and first and second solenoid valves are provided in the communication pipe. When the first solenoid valve is closed and the second solenoid valve (37) is opened, the gas container communicates with the intake pipe to reduce the pressure in the gas container. Thereafter, when the first solenoid valve is opened and the second solenoid valve (37) is closed, the gas container communicates with the liquid retainer to reduce the pressure in the liquid retainer. Then, the pressure of lubricant oil in the liquid retainer is lowered to gasify a refrigerant dissolving in the lubricant oil. As a result, lubrication malfunction caused due to lowering of the viscosity of the lubricant oil by dissolution of the refrigerant therein is avoided and the reliability of the hermetic compressor is enhanced.
