Rotary compressor and heat exchange system therewith

Abstract

The invention discloses a rotary compressor and a heat exchange system with the same. The rotary compressor comprises a shell, a liquid storage device, a compressing mechanism, an enthalpy increasing pipe and a switching device which can switch between a full load condition and a partial load condition, wherein the compressing mechanism is arranged in the shell and comprises a main bearing, an auxiliary bearing, a first air cylinder and a second air cylinder; the first and second air cylinders are arranged between the main and auxiliary bearings and are separated by a clapboard; the first air cylinder is internally provided with a first compression chamber; the compressing mechanism is provided with an air nozzle, a first exhaust port and a first air suction port; the air nozzle and the first exhaust port are respectively communicated with the first compression chamber; the first air suction port is communicated with the liquid storage device and the first compression chamber respectively; the second air cylinder is internally provided with a second compression chamber; the compressing mechanism is provided with a second air suction port and a second exhaust port, which are communicated with the second compression chamber; the enthalpy increasing pipe is arranged outside the shell and is communicated with the air nozzle and the second air suction port respectively. The rotary compressor has high operation efficiency, a wide range of application and good low temperature heating effects.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a rotary compressor and a heat exchange system with the rotary compressor. Background technique [0002] In the rotary compressor in the related art, in a low-temperature environment, the low-temperature heating effect of the rotary compressor is poor due to the decrease of the evaporation temperature of the refrigerant, and the capacity of the heat exchange system is reduced. For this reason, some twin-cylinder compressors have appeared. However, when the compression load is small, the twin-cylinder compressors are still in a dual-cylinder operation mode, resulting in poor operating efficiency of the compressor. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention needs to provide a rotary compressor, which has a good low-temperature heating effect, c...
