Problems solved by technology

[0003] Rotary compressors can use R410A, R290 and other refrigerants. Due to the difference in refrigerant characteristics, the performance of rotary compressors using different refrigerants is quite different. The design of the compressor using R410A refrigerant uses R290 refrigerant. The price of the compressor is lower

Abstract

The invention discloses a rotary compressor and a refrigeration circulation device comprising same. The rotary compressor adopts an R290 refrigerant and comprises a shell, N cylinders and a crankshaft, wherein the shell comprises a main shell, an upper shell and a lower shell; a cylinder cavity and a sliding sheet groove are formed in each cylinder; a piston capable of eccentrically rotating is arranged inside each cylinder cavity; the total displacement of the rotary compressor is Q sum (cm<3>); Q sum is NQ; Q is displacement of each cylinder; the inner diameter of the main shell is D(cm); the total displacement Q sum and the inner diameter D of the main shell meet the following relation formula: Q sum is greater than or equal to 2.1 and less than or equal to 4; the displacement Q of each cylinder is phi(d12 / d22)*h / 4; d1 is the inner diameter of the corresponding cylinder; d2 is the outer diameter of the piston of the corresponding cylinder; h is the height of the corresponding cylinder. Through the rotary compressor according to the embodiment of the invention, the cost performance of the rotary compressor adopting the R290 refrigerant can be improved.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a rotary compressor and a refrigeration cycle device with the same. Background technique [0002] Rotary compressors generally include a compression mechanism and a motor in the housing. The compression mechanism includes a cylinder. The main bearing and the auxiliary bearing are respectively arranged on both sides of the cylinder. The crankshaft runs through the auxiliary bearing, the cylinder and the main bearing in the axial direction. The piston sleeve is set on the eccentric part of the crankshaft. The motor includes a stator and a rotor. The main shaft of the crankshaft is connected with the rotor. The rotor drives the crankshaft to rotate, and the eccentric part of the crankshaft drives the piston to roll. It is connected to the outer circle of the piston and reciprocates in the slide groove of the cylinder under the push of the piston. [0003] Rotary compressors can use R41...
