Rotary compressor and its compression device, air conditioner

Abstract

The invention discloses a compression unit of a rotary compressor. The compression unit comprises a cylinder; an upper bearing and a lower bearing which are used for forming a chamber together with the cylinder; a piston which is used for forming a working space together with the inner wall of the chamber; a first slide sheet and a second slide sheet which are used for dividing the working space into a first working cavity and a second working cavity; a first air suction port and a second air suction port which are both communicated with the working space; and a first air exhaust port and a second air exhaust port which are both communicated with the working space. The first air suction port and the second air suction port are designed to accord with a formula 0.25<=V1S2 / S1V2<=4, wherein V1 and V2 are used for representing maximum volumes of the first working cavity and the second working cavity respectively, and S1 and S2 are used for representing opening areas of the first air suction port and the second air suction port respectively. The compression unit is capable of improving torque fluctuation of the rotary compressor, reducing vibration of the rotary compressor effectively, and reducing noise and cost increasing.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a compression device of a rotary compressor, a rotary compressor with the rotary compressor, and an air conditioner with the rotary compressor. Background technique [0002] The existing single-cylinder rotary compressor, as shown in Figure 1, has the advantages of simple processing and good performance, and is widely used in room air conditioners. However, since the torque fluctuation during the operation of the compressor basically determines the vibration amplitude of the compressor, the greater the vibration of the compressor, it will not only seriously affect the reliability of the compressor and air conditioner, but also cause serious noise problems. [0003] Due to the single-cylinder eccentric compression technology, the torque of the compressed gas varies greatly during the use of the single-cylinder rotary compressor, such as Figure 4 In the "moment A" shown.

Problems solved by technology

However, compared with the single-cylinder rotary compressor, the double-cylinder rotary compressor has the disadvantages of a large number of components and a substantial increase in production cost. Moreover, due to the addition of a set of compression components, the friction pair is increased, making the friction Increased loss
