Compressor and refrigerating device comprising same

Abstract

The invention discloses a compressor and a refrigerating device comprising the same. The refrigerating device comprises the compressor, a reversing assembly, an outdoor heat exchanger, an indoor heatexchanger, a switching flow channel and a first one-way device, wherein the compressor comprises a shell, a first cylinder and a second cylinder; the reversing assembly comprises a first valve port, asecond valve port, a third valve port and a fourth valve port; the first valve port is connected with an exhaust pipe, and the second valve port is connected with a gas suction pipe; the first end ofthe switching flow channel is connected with the fourth valve port, or the first end of the switching flow channel is connected to the position between the indoor heat exchanger and a throttling device; the second end of the switching flow channel communicates with a slip sheet cavity of the second cylinder; an exhaust duct of the first cylinder communicates with the gas inlet end of the first one-way device; the gas outlet end of the first one-way device communicates with the space in the shell. According to the refrigerating device, the working state of the refrigerating device can be selected according to the actual working conditions through the switching flow channel; thus, energy consumption of the refrigerating device can be reduced, and the practicality of the refrigerating devicecan be improved.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a compressor and a refrigeration device thereof. Background technique [0002] Generally, an air conditioner adopts a two-stage compression method to improve its own low-temperature heating capacity, and can make the air conditioner normally perform heating work under ultra-low temperature conditions. However, the two-stage compression and single-stage compression working modes of traditional air conditioners cannot be switched. Under normal working conditions, although two-stage compression can meet the working requirements of the air conditioner, the air conditioner still uses If the way of two-stage compression is carried out, the energy consumption of the air conditioner will be increased, and the practical performance of the air conditioner will be reduced. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in t...
