Embodiment Construction

[0034] Fig. 1 shows a scroll compressor of a first embodiment.

[0035] The scroll compressor has a compression mechanism part and a motor mechanism part in the airtight container 20 . The compression mechanism unit is disposed above the airtight container 20 , and the motor mechanism unit is disposed below the compression mechanism unit. A suction pipe 1 and a discharge pipe 21 are provided on the upper portion of the airtight container 20 . An oil storage portion 22 for storing lubricating oil is provided at a lower portion inside the airtight container 20 .

[0036] In the compression mechanism part, the fixed scroll 2 and the orbiting scroll 4 form a compression chamber 5 composed of a plurality of compression spaces. The fixed scroll member 2 is constituted by erecting a wrap 2a from an end plate 2b, and the orbiting scroll member 4 is constituted by erecting a wrap 4a from an end plate 4b. The compression chamber 5 is formed by engaging the wrap 2a and the wrap 4a betwe...

Abstract

According to a scroll compressor of the present invention, lubricant is supplied to a compression chamber in the proportions of 2% by weight or more and less than 20% by weight of the lubricant to the sucked refrigerant amount. With this, it is possible to provide an efficient scroll compressor even when carbon dioxide is used as the refrigerant.

Description

technical field [0001] The present invention relates to a scroll compressor, which forms a compression chamber by meshing a wrap of a fixed scroll member and a wrap of a revolving scroll member, and constrains the rotation of the revolving scroll member so that it moves along a circle. The orbit rotates, and the compression chamber formed between the wrap of the fixed scroll and the wrap of the orbiting scroll moves while changing volume to discharge the sucked refrigerant. Background technique [0002] In the field of refrigerating and air-conditioning for home use and business use, reciprocating compressors, rotary compressors, and scroll compressors are used as hermetic compressors for refrigerating and air-conditioning. These reciprocating compressors, rotary compressors, and scroll compressors have been developed by making use of their respective characteristics in terms of cost and performance. [0003] For the purpose of soundproofing and easy maintenance, a hermetic...
