COMPRESSOR WITH LIQUID INJECTION COOLING

摘要

A positive displacement rotary compressor is designed for near isothermal compression, high pressure ratios, high revolutions per minute, high efficiency, mixed gas/liquid compression, a low temperature increase, a low outlet temperature, and/or a high outlet pressure. Liquid injectors provide cooling liquid that cools the working fluid and improves the efficiency of the compressor. A gate moves within the compression chamber to either make contact with or be proximate to the rotor as it turns.

主权项

1. A method of operating a compressor having a casing defining a compression chamber, an inlet port into the compression chamber, and a rotatable drive shaft configured to drive the compressor, the method comprising:
moving a working fluid into the compression chamber through the inlet port, wherein the working fluid is a multi-phase fluid that includes gas and liquid components and has a liquid volume fraction at the inlet port of at least 0.5%; and compressing the working fluid using the compressor such that a single stage pressure ratio of the compressor is at least 3:1.
