A hermetic refrigeration compressor, characterized in that the hermetic refrigeration compressor is further provided with a starting means for starting the electric motor to rotate at a low speed when the gas-liquid discrimination sensor determines that the gas-liquid discrimination sensor is in a liquid phase. (2) In a hermetic refrigeration compressor that has an electric motor and a compression mechanism built into a hermetic housing, a gas-liquid discrimination sensor is installed in the hermetic housing at a position corresponding to the permissible liquid refrigerant stagnation level, and the gas-liquid discrimination sensor is A starting means is provided which applies a low voltage to the electric motor to the extent that it does not rotate when the liquid discrimination sensor discriminates that the liquid phase is present, and then returns to the normal operating voltage when the gas liquid discrimination sensor discriminates that the gas phase is present. A hermetic refrigeration compressor featuring:
