Benefits of technology

This new design for an air conditioner compressor has several advantages over previous designs: it reduces the amount of compressed fluid that escapes from certain parts inside due to excessive heat generated during use; eliminates the risk of damage caused when there are too many small bubbles entering through these openings or other areas on the rotating part's surface (which can lead to pitting) while still providing effective cooling performance without adding extra weight or complexity.

Problems solved by technology

This patented technical problem addressed in previous designs was how to improve the performance and durability of horizont compressors without causing instabilities or excessive friction caused by nonsymmetrical expansion angle geometry between different parts within each stage (compression/expansion) due to uneven distribution of compressed fluid over both stages' surfaces.

Abstract

The invention discloses a horizontal enhanced vapor injection compressor with an asymmetric extension angle scroll plate, and relates to the technical field of scroll compressors, in particular to a horizontal enhanced vapor injection scroll compressor. A scroll extension angle on a fixed scroll plate and a scroll extension angle of a movable scroll plate form an asymmetric structure; a compression cavity A1 is formed between the scroll inner side of the fixed scroll plate and the scroll outer side of the movable scroll plate; a compression cavity B1 is formed between the scroll inner side of the movable scroll plate and the scroll outer side of the fixed scroll plate; during the enhanced vapor injection communication gas supply period, gas mixing between the compression cavity A1 and the compression cavity B1 is avoided through an enhanced vapor injection communication hole; and in the enhanced vapor injection communication air supply period, air mixing between each of the compression cavity A1 and the compression cavity B1 and a pressure tapping hole is avoided. Only one part of the end face of the fixed scroll plate is provided with an enhanced vapor injection communication hole. The enhanced vapor injection communication hole must be formed in a specified S region. The S region is an intersection region of two movable scroll tooth crests when the movable scroll plate revolve for 0 degree and 180 degrees on the end surface of the fixed scroll plate. The enhanced vapor injection communication hole is formed in a manner of one or more round holes and groove-shaped holes.
