    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: The present invention relates a scroll compressor. According to an exemplary embodiment of the present invention, the scroll compressor includes: an orbiting scroll configured to be seated on one surface of a main frame and provided with a plurality of seating grooves along a circumferential direction; a stepped part configured to be formed in the seating groove; a ring member configured to be inserted into the seating groove and have a lower surface adhering to the stepped part; and a guide pin configured to have one end fixed to the main frame and the other end extended in an inside length of the ring member, in which the guide pin has the end maintained in a spaced state from the stepped part.

    Abstract: The present disclosure relates to a scroll compressor, and it is possible to constitute a depressurized resistance value of a first orifice disposed on an oil recovery part to be lower than a depressurized resistance value of a second orifice, thereby maintaining/enhancing volume efficiency upon driving under a high pressure condition where a pressure of discharged refrigerant is high by increasing the back pressure of a back pressure chamber.

    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.
