Abstract

A reciprocating compressor comprising a drive unit (10) disposed within a sealed housing (86) and generating a reciprocating force; for performing compression on a refrigerant when subjected to a reciprocating force generated by the drive unit (8) a compression unit (10) for operation; and a lubrication unit (12) for supplying lubricant to the drive unit (8) and the compression unit (10) to complete the lubrication operation. Hydrocarbons consisting of carbon and hydrogen, a natural refrigerant, are used as refrigerants. The lubricant is a paraffin-based mineral lubricant, which is a mineral oil and harmonizes well with the natural refrigerants used in refrigerators. Therefore, the lubricating performance is improved and thus the 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 which can be used for The refrigerant of the refrigerator has a good compatibility lubricant to improve the lubricity and improve the performance of the refrigerator. Background technique [0002] Since chlorofluorocarbons (CFCs) as refrigerants used in refrigerators, air conditioners, or the like are recognized as source substances for depleting the ozone layer of the stratosphere, research on refrigerant substitutes is currently being actively conducted. [0003] CFC includes R11 (trichloromonogluoromethane), R12 (dichlorodifluoromethane), R13, etc. Among them, R12, which is mainly used as a refrigerant for refrigerators, is a source material that leads to the reduction of the ozone layer and the greenhouse effect , is a material subject to regulatory restricti...
