Abstract

The invention relates to a multi-stage compressor. The multi-stage compressor comprises an air supplement mechanism, a low-pressure-stage cavity and a high-pressure-stage cavity, wherein the air supplement mechanism comprises air supplement openings and a punching component; the air supplement openings are arranged at the upstream of an exhaust air flow of the low-pressure-stage cavity; the punching component is arranged at the downstream of the exhaust air flow of the low-pressure-stage cavity; a liquid coolant sprayed in through the air supplement openings is mixed exhausted air of the low-pressure-stage cavity and impacts the punching component; and the liquid coolant is dispersed and mixed again with the exhausted air and enters the high-pressure-stage cavity. By adopting multi-stage compressor, the liquid coolant can be fully mixed with the exhausted air of the low-pressure-stage cavity and then enters the high-pressure-stage cavity for secondary compression, so that uniformly of an air supplement flow field is improved, and secondary energy efficiency is improved.

Description

technical field [0001] The invention relates to the field of cooling and refrigeration systems, in particular to a multistage compressor. Background technique [0002] Due to the two-stage compression, the two-stage screw compressor can achieve a large compression ratio. Therefore, it has a wide operating range and has become an innovative trend in compressor development. The energy efficiency of the compressor decreases due to heat loss and other reasons during operation. In order to improve energy efficiency, air supplementation can be used. Generally, the compressor supplies air in the rotor cavity, while the two-stage compressor can supply air between the two-stage rotors, and at the same time, it plays the role of cooling the motor. [0003] For two-stage compressors, the air supply is carried out in the form of liquid refrigerant. After the liquid refrigerant is sprayed from the air supply port, it will directly enter the secondary compression because the spray liquid...
