我国容积式制冷压缩机名义工况一致性研究

Research on the Harmonization of Nominal Condition of Positive Displacement Refrigerant Compressors for Chinese Standards

论述了我国容积式制冷压缩机标准名义工况一致性研究的需求,总结了中国、美国和欧洲现行相关标准的名义工况现状,发现现行标准工况中蒸发温度、冷凝温度等关键参数存在较大的不一致性。介绍了中美标准研究进展,归纳出新的压缩机标准工况参数在向一致性方向发展,且更加符合压缩机在主机中的实际应用情况。提出建立我国容积式制冷压缩机标准名义工况一致性的具体的研究工作方向。

This paper demonstrated the importance of consistency on nominal working conditions in positive displacement compressor standards.Based on summarizing the status of standards for positive displacement refrigerant compressor in USA, Europe and China, the nominal conditions in these standards are contrasted.Key parameters such as evaporation temperature, condensation temperature of existing standard condition are inconsistency.Research progress of American and Chinese standard is introduced.Summed up the revision of compressor standards that key parameters are in the direction of consistency, and more in line with the actual application of the compressor.Nominal conditions harmonization for positive displacement refrigerant compressor in China is related research ideas are discussed.
