Embodiment Construction

[0036] Preferred embodiments of the present invention will now be described in detail with reference to examples shown in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0037] figure 1 It is a cross-sectional view of a scroll compressor according to an embodiment of the present invention.

[0038] see figure 1 , The variable capacity scroll compressor of the present invention includes: a conventional compression part, a bypass part for changing a compression amount, and a bypass control part for controlling the bypass part.

[0039] The conventional compression part includes: a sealing chamber 11 used to define a closed chamber; a sealing plate 12 arranged in the sealing chamber 11 to divide the sealing chamber into a low-pressure inlet chamber 13 and a high-pressure exhaust chamber 14; connected with the inlet chamber 13 The air intake passage 22, so that the fluid to be co...

Abstract

Disclosed is a variable capacity scroll compressor in which a high-pressure fluid within a thermodynamic cycle is introduced into the inside of the compressor to increase the compression volume and also the fluid inhaled / exhausted from the compressor allows the fluid being compressed to be bypassed in multi-stages, thereby varying the capacity of the compression fluid.

Description

technical field [0001] The present invention relates to a scroll compressor, and more particularly, to a variable capacity scroll compressor configured to vary the discharge volume of the compressor in multiple stages. Background technique [0002] In general, a refrigeration system for an air conditioner or a refrigerator lowers the temperature of an enclosed space by absorbing and releasing heat through a refrigerant flowing in a refrigeration cycle. [0003] This refrigeration system will complete a series of cycles of compression, condensation, expansion and evaporation of the refrigerant. A scroll compressor is used to complete the compression process in this series of cycles. [0004] Since many published documents disclose such scroll compressors, a detailed description of the general structure and operation of the scroll compressors is omitted here. [0005] The reason why the compression amount of the scroll compressor should be changed will be explained below. ...
