螺杆式制冷压缩机的热力完善度统计分析

Statistical analysis on thermodynamical perfectness of screw refrigeration compressor

将国内外不同品牌的高温用螺杆式制冷压缩机能效比的检测和样本数据(针对3种制冷工质、2种冷凝压力)转换成热力完善度,进行统计分析,提出将能效比和热力完善度均作为反映耗能水平的评价值,可以更好地解决不同制冷剂、不同工况的差异问题。

According to inspection data and sample data for different screw refrigeration compressors applied to high-temperature at home and broad,transforms their EER to thermodynamical perfectness with three kinds of refrigerants,two kinds of condensing pressure.Based on the statistical analysis,puts forward that EER thermodynamical perfectness should be both considered as evaluation values reflecting the energy consumption level,which can better solve the difference problems of different refrigerants and working conditions.
