Benefits of technology

[0015] Therefore, it is an object of the present invention to provide a reciprocating compressor that is capable of improving a lubrication performance by using a lubricant in good harmony with a natural refrigerant used for a refrigerator, and thus enhancing a performance of a reciprocating compressor.

Problems solved by technology

Therefore, if the lubricant used for the reciprocating compressor compressing the natural refrigerant is not well harmonized with the refrigerant of the refrigerator, the oil would be leaked.
Then, oil circulation is deteriorated to degrade a heat transfer performance of the refrigerator and a lubrication performance, resulting in that frictional portions of each motional part are abraded and thus each part is damaged.

Embodiment Construction

[0027]FIG. 1 is a sectional view of a general reciprocating compressor for compressing a refrigerant.

[0028] As shown in FIG. 1, the general reciprocating compressor includes: a hermetic container 6 to which a suction pipe 2 for sucking a refrigerant and a discharge pipe 4 for discharging a compressed refrigerant are connected, a driving unit 8 disposed inside the case 6 and generating a reciprocal motional force; a compression unit 10 for receiving a reciprocal motional force generated from the driving unit 8 and performing a compressing operation on the refrigerant; and a lubrication unit 12 for performing a lubricating operation on each motional portion of the driving unit 8 and the compression unit 10.

[0029] The driving unit 8 includes: a cylindrical outer stator 16 fixed by a support frame 14 fixed inside the hermetic container 6; an inner stator 18 disposed with a certain air gap with an inner circumferential surface of the outer stator 16; a winding coil 20 wound at the oute...

Abstract

A reciprocating compressor includes a driving unit (10) disposed inside a hermetic container (86) and generating a reciprocal motional force, a compression unit (10) for performing a compressing operation on a refrigerant upon receiving the reciprocal motional force generated from the driving unit (8); and a lubrication unit (12) for supplying a lubricant to each motional portion of the driving unit (8) and the compression unit (10) to perform a lubrication operation. Hydrocarbon consisting of carbon and hydrogen, a sort of natural refrigerant, is used as the refrigerant. The lubricant is a paraffin-based mineral lubricant, which is a sort of mineral oil and well harmonized with the natural refrigerant used for a refrigerator. Accordingly, a lubricating performance is improved and thus a performance of the reciprocating compressor can be enhanced.

Description

TECHNICAL FIELD [0001] The present invention relates to a reciprocating compressor for compressing a refrigerant in a refrigerator, and more particularly, to a reciprocating compressor for compressing a refrigerant that is capable of improving a lubricating performance by using a lubricant with an excellent compatibility with a refrigerant used for a refrigerator and improving a performance of the refrigerator. BACKGROUND ART [0002] As chlorofluorocarbon (CFC), a refrigerant used for a refrigerator, an air-conditioner or the like, has been known as a source material damaging an ozone layer of the stratosphere, researches on a substitute refrigerant is being actively conducted. [0003] The CFC comprises R11 (trichloromonogluoromethane), R12 (dichlorodifluoromethane), R13 and the like, of which R12 mainly used as a refrigerant for a refrigerator is one of regulation-subject materials as being a source material causing an ozone layer reduction and generating a global warming effect.
