Compression assembly, scroll compressor and air conditioner

Abstract

The invention discloses a compression assembly, a scroll compressor and an air conditioner, and relates to the technical field of compressors. The compression assembly comprises a dynamic scroll plate and a crankshaft. The dynamic scroll plate comprises dynamic scroll teeth, the maximum outer diameter of the outer side molded lines of the dynamic scroll teeth is De, and the tooth height of the dynamic scroll teeth is h. The crankshaft comprises a long shaft part and an eccentric part, the eccentric part is provided with a first tangent plane, and the included angle between a reference plane formed by the central axis of the long shaft part and the central axis of the eccentric part and the first tangent plane is the distance Ror between the central axis of the long shaft part and the central axis of the eccentric part; the angle characteristic parameter of the first tangent plane and the eccentric distance characteristic parameter H2 of the crankshaft are equal to Ror2 / (De*h); and H1+alphaH2 is greater than or equal to 0.10 and less than or equal to 0.22, and alpha is greater than or equal to 8.5 and less than or equal to 11.2. According to the compression assembly, the angle characteristic parameter of the first tangent plane and the eccentric distance characteristic parameter of the crankshaft are designed in a proper range, so that small contact force is kept between the dynamic scroll plate and a static scroll plate, corresponding friction power consumption is small, meanwhile, the situation that leakage occurs as the dynamic scroll plate and the static scroll plate are separated is not likely to occur, and the energy efficiency and reliability of the scroll compressor are improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compression assembly, a scroll compressor and an air conditioner. Background technique [0002] In related technologies, a scroll compressor includes a fixed scroll, a movable scroll, and a crankshaft. When the crankshaft drives the movable scroll to move relative to the fixed scroll, a plurality of compression chambers are formed between the movable scroll and the fixed scroll, and the compression chamber realizes Suction, compression and discharge of refrigerant. There is a contact force between the movable scroll and the fixed scroll. When the contact force is too large, the friction power consumption of the scroll compressor is large. When the contact force is too small, the separation between the movable scroll and the fixed scroll is easy to cause Leakage in the pump body affects the energy efficiency of the scroll compressor, so designing an appropriate contact forc...

Problems solved by technology

There is a contact force between the movable scroll and the fixed scroll. When the contact force is too large, the friction power consumption of the scroll compressor is large. When the contact force is too small, the separation between the movable scroll and the fixed scroll is easy to cause Leakage of the pump body affects the energy efficiency of the scroll compressor, so designing an appropriate contact force range is the key to solving the energy efficiency and reliability of the scroll compressor
