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.

The present invention relates to a scroll compressor. The baseplate part of an oscillating scroll has a pressure channel via which an external space of a boss part and an innermost chamber positioned farthest radially inward among a plurality of compression chambers and communicate. When a motor is rotated backwardly, a refrigerant gas flows from the external space of the boss part via the pressure channel to the innermost chamber so that oil supply via an oil supply channel is performed on the basis of a decrease in pressure of the external space of the boss part.

The present disclosure relates to a scroll compressor. According to the present disclosure, in a shaft penetration scroll compressor in which an eccentric portion of the rotation shaft is overlapped with a orbiting wrap of the orbiting scroll in a radial direction, when a bearing area between the orbiting scroll and the rotation shaft is A and an end plate area of the orbiting scroll is B, A/B may be formed in a range of 0.035-0.085, and thus it may be possible to obtain a sufficient volume ratio and Sommerfeld number as well as reducing the overall size of the compressor, thereby reducing a frictional loss and abrasion in the compressor.
