Abstract: A gas compressor includes a compression mechanism, a separator tank that introduces lubricating oil to be supplied to the compression mechanism and a mixed fluid of a working fluid and lubricating oil discharged from the compression mechanism and separates the lubricating oil. An oil cooler cools the lubricating oil from the separator tank. An oil circulation path supplies cooled lubricating oil to the compression mechanism. The gas compressor includes a suction temperature sensor that detects suction temperature of the working fluid, a discharge pressure sensor that detects discharge pressure of the compressed working fluid, a rotation speed sensor that detects rotation speed of the motor. A lubricating oil state estimation unit estimates the temperature of the lubricating oil based on the detected suction temperature, discharge pressure, and rotation speed of the motor. The lubricating oil state estimation unit uses this result to estimate the deterioration state of the lubricating oil.

Abstract: A liquid-cooled rotary compressor includes a compressor main body having a compression chamber formed by a fixed wall and a rotating wall and compressing gas, and a liquid injection path for injecting a coolant into the compression chamber, and adjusts a discharge flow rate by changing a rotational speed of the rotating wall. The compressor includes a liquid amount adjusting unit that adjusts an amount of the coolant supplied from the liquid injection path to the compressor main body according to a change in the rotational speed of the rotating wall, and a compressed gas supply path that supplies compressed gas to a downstream side of the liquid amount adjusting unit in the liquid injection path. The compressed gas is supplied from the compressed gas supply path to the liquid injection path according to the amount of the coolant supplied to the compressor main body.
