旋转式压缩机变压比工况下高效节能特性解析 丛丽 沈建芳 周易 米廷灿 （上海日立电器有限公司，上海市浦东金桥出口加工区云桥路1051号 201206） 摘 要 随着世界能源的紧缺，新的能源标准即将实施，对家用电器中占重要地位的空调器也提出了更高 的节能要求。压缩机作为空调器的核心部件，研究其在空调器中的实际应用技术，特别是空调实际运行条 件，即变压比工况下的性能对于空调器的节能具有重要意义。在对压缩机结构和空调器实际运行条件进行 理论分析和探讨的基础上，通过对排量基本相当的一种新型旋转式压缩机和普通涡旋式压缩机在不同压比 下进行了性能对比测试。试验结果表明：在压缩机标准工况（ASH工况下）两者性能试验结果相当的条件 下，进行变压比工况测试，新型旋转式压缩机比普通涡旋式压缩机具有更优良的性能；由于空调机的实际 运行工况是变压比工况，新型旋转式压缩机更宜与空调机的实际运行过程相匹配，该产品具有用户使用经 济省电的特点即具有环保节能的优势。 关键词 压缩机 空调 变压比工况 性能 节能 ANALYSIS THE SPECIALITY OF ROTARY COMPRESSORS ABOUT HIGH EFFICIENCY AND ENERGY SAVING IN VARIABLE COMPRESSION RATIO CONDITION Cong Li Shen Jianfang Zhou Yi Mi Tingcan （Shanghai Hitachi Electrical Appliances CO.,LTD., 1051 Yunqiao Rd. Pudong Jinqiao Shanghai,201206） Abstract Residential air conditioners which play an important role in domestic electrical appliances are required more efficient due to the new energy standard caused by world wide energy crisis. Because the compressor is the core component in AC, researching into the technolodge of applying compressor to AC,especially it’s performance in real condition (variable condition) is very important for AC saving energy. analysis and discussion about the compressors and AC is presented under the structure of compressor and real AC operation process. Then the performance of two different kinds of compressors is experimentally measured and compared, common screw compressors and new type rotary compressor, whose displacement is roughly equal. The results shows that performance of the new type rotary compressor is as good as the common screll compressor in standard working condition, however the performance of the new type rotary compressors is more excellent than the common scroll compressors in variable conditi
