Abstract: The present disclosure relates to a method of controlling a compressor, and may include: pilot driving which drives a compressor of an air conditioner by receiving a start signal; determining whether oil is short which compares the oil amount of the compressor, driven in the pilot driving, with a predetermined reference oil amount; normal driving which maintains the driving of the compressor when it is determined that the oil amount is the reference oil amount or more; and stopping which stops the driving of the compressor when it is determined that the oil amount is smaller than the reference oil amount. Accordingly, by stopping the compressor when the oil is short, it is possible to prevent damage to the compressor.

Abstract: A scroll compressor that includes a rotating shaft, an eccentric bush having a recess, into which one end of the shaft is inserted, and an eccentric portion eccentric to the shaft, an orbiting scroll operatively connected to the eccentric portion for orbiting, a fixed scroll engaged with the orbiting scroll, and a buffer member interposed between the one end of the shaft and the recess. Therefore, it is possible to prevent damage to the scrolls due to liquid refrigerant compression during initial operation and to prevent an impact sound between the shaft and the eccentric bush due to the rotational clearance therebetween.

Abstract: A scroll compressor capable of improving the performance and efficiency of the compressor by increasing the amount of refrigerant discharged from a compression chamber by introducing not only refrigerant at suction pressure but also refrigerant at an intermediate pressure to the compression chamber of the scroll compressor, capable of freely changing the position of a port by simplifying the shape of an injection valve assembly and by disposing a fastening member on an introduction chamber side, and capable of compactifying the injection valve assembly.

Abstract: A compressor control method, including: when driving of a compressor of a vehicular air conditioner starts, a determining step of determining whether a condition for limiting an output of the compressor is satisfied by using at least one among whether a power supply unit of a vehicle is reset, a start-off period and the number of times the compressor is driven; an output limiting step of limiting an output of the compressor when the condition for limiting the output of the compressor is satisfied; a third determining step of determining an output limiting driving time of the compressor driven in a state in which the output is limited by the output limiting step; a normal driving step of canceling the output limitation of the compressor and normally driving the compressor when the output limiting driving time of the compressor is equal to or greater than a predetermined reference time.

Abstract: Disclosed herein may be an electric compressor. The electric compressor may include: a rear housing having a discharge chamber into which refrigerant is discharged; and an oil separator disposed in the discharge chamber and having a refrigerant inlet hole through which the refrigerant is drawn into the oil separator. The discharge chamber may protrude in a multi-stepped manner outwards from the rear housing such that a volume of the rear housing is increased, and based on the oil separator, an internal space of the discharge chamber may be divided into spaces having different volumes.
