Scroll compressors and fixed and orbiting scroll components

Abstract

The invention discloses a vortex compressor as well as a fixed vortex member and a movable vortex member. On the one hand, the vortex compressor comprises a compression mechanism, an exhaust port and an emission space, wherein the compression mechanism comprises a fixed vortex member and a movable vortex member, the fixed vortex member comprises a fixed vortex end plate and a fixed vortex roll, the movable vortex member comprises a movable vortex end plate and a movable vortex roll, and the fixed vortex roll and the movable vortex roll are combined together to limit a plurality of compression chambers including first compression chambers and second compression chambers; the exhaust port is suitable for communicating with the first compression chambers; and the emission space is suitable for communicating with the exhaust port. The first compression chambers, the exhaust port and the emission space form a high-pressure area. The vortex compressor also comprises a communicating passage which is set to ensure that at least one of the second compression chambers and the high-pressure area can be communicated with each other before a vortex roll separation point. According to the invention, the pressure of the first / center compression chambers can be changed more gently, so that the problem of high noise can be effectively solved, and the energy efficiency ratio and working stability of the compressor can be improved.

Description

Technical field [0001] The present invention relates to a scroll compressor, a fixed scroll component and a movable scroll component, and more particularly, to a scroll compressor with improvements in pressure fluctuations in a central compression chamber. Background technique [0002] The scroll compressor includes a compression mechanism composed of a fixed scroll member and a movable scroll member. The fixed scroll member includes a substantially spiral fixed scroll extending from an end plate thereof, and the movable scroll member includes a substantially spiral movable scroll extending from an end plate thereof. The spiral fixed scroll and the spiral movable scroll are mutually engaged to define a plurality of closed crescent-shaped compression chambers therebetween. The movable scroll member is driven by, for example, an electric motor to perform translational rotation relative to the fixed scroll member (that is, the axis of the movable scroll member revolves with respect...

Problems solved by technology

However, in the case of using a silencer, it is generally only possible to suppress noise in a partial frequency range of the entire frequency band (such as high-frequency noise)

Moreover, due to the placement of the muffler, it also causes a pressure drop which adversely affects the performance of the compressor and the entire refrigeration system

In addition, additionally providing a muffler complicates the manufacturing process due to an increase in the number of parts, increases the manufacturing cost, and requires an additional installation space for the muffler, and also degrades the operational reliability of the compressor accordingly.
