降低制冷系统压缩机排气温度的方法研究
Research on Method of Reducing Compressor Exhaust Temperature in Refrigeration System
摘要
Abstract
For the problem of high exhaust temperature of R32 refrigeration system,the feasibility of the advantages and disadvantages of four methods of the current mainstream(second gas-injection,two-stage compression,liquid spray and wet compression) was analyzed and discussed from the aspects of system performance.A small variable flow chiller was set up,emphasizing the use of wet compression to optimize the exhaust temperature of the R32 refrigeration system.The results show that:the wet compression method is the best choice to reduce the exhaust temperature for R32 refrigeration system;the structural characteristics of the rolling rotor compressors make a good solution to the problem of the exhaust temperature of the R32 refrigeration system; under the condition of standard air conditioning, the wet compression method can significantly reduce the R32 exhaust temperature.In practical engineering,the exhaust temperature of R32 system can be reduced by controlling the suction dryness of the compressor, and the optimal system performance coefficient can be obtained.关键词
