Title:
REFRIGERATION SYSTEM AND ROTATING COMPRESSOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/123765
Kind Code:
A1
Abstract:
A refrigeration system and rotating compressor (100) thereof, the rotating compressor (100) comprising: an air cylinder (1) provided with an air cylinder chamber (11) therein; a piston (2) disposed in the air cylinder chamber (11); an upper bearing (3) disposed on an upper end face of the air cylinder (1); and an lower bearing (4) disposed on a lower end face of the air cylinder (1). The area of a peripheral surface of the piston (2) is S1; the area of an inner wall of the air cylinder (1) is S2; the contact area of the upper bearing (3) and a crescent-shaped compression chamber surrounded by the air cylinder (1) and the piston (2) is S3; the contact area of the lower bearing (4) and the crescent-shaped compression chamber surrounded by the air cylinder (1) and the piston (2) is S4; the volume of the air cylinder chamber (11) is V; the rotating compressor (100) satisfies the following relational formula: 0.37 mm-1 ≤ S/V ≤ 0.51 mm-1, wherein S represents the sum of contact areas of air in a compression chamber, and S = S1 + S2 + S3 + S4.
