Abstract: An air conditioner is provided that may include at least one compressor that compresses a refrigerant to a high pressure; a plurality of heat exchanger that condenses the refrigerant compressed in the at least one compressor; a plurality of outdoor valves, respectively, provided at an outlet side pipe of the plurality of heat exchangers; a gas liquid separator that separates the refrigerant into gas and liquid refrigerants and supplies the gas refrigerant to the at least one compressor; and one or more bypass devices connected to the outlet side pipe of one or more of the plurality of heat exchangers and an inlet side pipe of the gas liquid separator, the one or more bypass devices controlling a flow of the liquid refrigerant. During a cooling low load operation in which a portion of the plurality of heat exchangers is operating, a liquid refrigerant loaded into a heat exchanger of the plurality of heat exchangers, which is not operated, may flow through the one or more bypass device.

Abstract: An accumulator and an air conditioner having the same are provided. The air conditioner may include at least one indoor unit connected to an outdoor unit, the outdoor unit including a compressor compressing refrigerant and an accumulator transferring gas refrigerant into the compressor. The accumulator may include a housing, an inflow tube guiding refrigerant into the housing through a guide tube, and a discharge tube discharging the refrigerant from the housing. A portion of the guide tube protrudes out of the housing, and a distance between the discharge tube and a bottom of the housing is greater than that between the protruded portion of the guide tube and the bottom of the housing.

Abstract: An air conditioner and a fluid filling method for an air conditioner are provided. The method may include operating, by the air conditioner, in a fluid supply mode, to fill a group of pipes with a fluid, such as water, determining whether an amount of the fluid in the group of pipes is appropriate while continuously filling the group of pipes with the fluid, and outputting, by an output device, information indicating that filling of the fluid has been completed when it is determined that the amount of the fluid is appropriate. The fluid supply mode may include a first fluid supply mode in which fluid is supplied while the outdoor unit is stopped, and a second fluid supply mode in which the fluid is supplied while the outdoor unit is operated.

Abstract: An air conditioner is provided. The air conditioner includes a compressor for compressing a refrigerant, an oil separator for separating an oil of the refrigerant discharged from the compressor to collect the separated oil into the compressor, a condenser for condensing the refrigerant separated from the oil separator, and a supercooling part in which a main refrigerant that is the refrigerant condensed by the condenser is heat-exchanged with a branch refrigerant branched from the main refrigerant. At least a portion of the oil collected into the compressor passes through the supercooling part.
