| 20090133435 | Refrigerating Air-Conditioning Apparatus - A refrigerating air-conditioning apparatus, at least provided with no possibility that a foreign material returns to a compressor from an accumulator at a time of the pipeline-cleaning operation firstly, and provided with a possibility to perform a collecting operation for the foreign material in a short time secondary, is provided. | 05-28-2009 |
| 20100122550 | Hermetic compressor and refrigeration cycle device having the same - Disclosed are a hermetic compressor and a refrigeration cycle device having the same. An oil separator for separating oil from a refrigerant is installed outside a casing. The oil separated by the oil separator is recollected into the casing by an oil pump driven by a driving force of a driving motor. The oil is recollected from the refrigerant and fabrication costs are be reduced. A cooling capability of the refrigeration cycle device is enhanced, the compressor has a simplified configuration, and the fabrication costs are reduced. Because an outlet of a discharge opening through which oil is discharged to the casing from the oil pump is installed at a position lower than a minimum level of oil in the casing, the refrigerant is prevented from backflowing into an oil passage, and the occurrence of air bubbles on the surface of oil in the compressor may be prevented. | 05-20-2010 |
| 20100300139 | OIL SEPARATOR FOR AIR CONDITIONER - An oil separator for an air conditioner, which includes: a case having a cylinder portion, and a lid portion and a bottom portion respectively closing an upper side opening end and a lower side opening end of the cylinder portion; an inlet pipe which is connectable to a discharging outlet of a compressor and which penetrates the lid portion so that an end of the inlet pipe is located inside the case; an outlet pipe which is connectable to a condenser and which penetrates the lid portion so that an end portion of the outlet pipe is located inside the case and protrudes into the cylinder portion toward the bottom portion; and a mesh portion which is provided to the end of the inlet pipe. | 12-02-2010 |
| 20150369528 | COOLING SYSTEM AND REFRIGERATOR INCLUDING A COOLING SYSTEM - A cooling system and a refrigerator including a cooling system are provided. The cooling system may include a linear compressor including a reciprocating piston and a cylinder that accommodates the piston and having an outer circumferential surface, into which a refrigerant may be introduced, a refrigerant filter device provided in the linear compressor to filter the refrigerant introduced into one or more gas inflow of the cylinder, a condenser that condenses the refrigerant compressed in the linear compressor, and a dryer that removes foreign substances or oil from the refrigerant condensed in the condenser. The dryer may include a dryer body including a refrigerant inflow, through which the refrigerant condensed in the condenser may be introduced, and a refrigerant discharge, through which the refrigerant may be discharged, and an adsorption filter accommodated in the dryer body to filter the oil in the refrigerant introduced through the refrigerant inflow. | 12-24-2015 |
| 20150377531 | LINEAR COMPRESSOR AND REFRIGERATOR INCLUDING A LINEAR COMPRESSOR - A linear compressor and a refrigerator including a linear compressor is provided. The linear compressor may include a shell including a suction inlet, a cylinder provided in the shell to define a compression space for a refrigerant, a piston reciprocated in an axial direction within the cylinder, a discharge valve provided at one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, at least one nozzle disposed in the cylinder to introduce at least a portion of the refrigerant discharged through the discharge valve into the cylinder, and at least one filter provided in the shell. The at least one filter may be disposed in a refrigerant passage defined from the suction inlet to the at least one nozzle via the discharge valve. Foreign substances or oil contained in the refrigerant introduced into the at least one nozzle may be filtered while passing through the at least one filter. | 12-31-2015 |
