Core Points - Gree Electric Appliances, in collaboration with Hefei General Machinery Research Institute and Tsinghua University, has successfully established two international standards for refrigeration compressors, namely "Performance Evaluation of Positive Displacement Refrigeration Compressors" (ISO 18501:2025) and "Performance Evaluation of Centrifugal Refrigeration Compressors" (ISO 18483:2025) [1][2] - The establishment of these standards marks a significant achievement for China, a major compressor manufacturing country, which previously lacked a voice in setting international standards [1][2] - The global refrigeration compressor market is projected to grow from 128.55 billion yuan in 2023 to 177.22 billion yuan by 2029, highlighting the importance of developing efficient compressors and promoting standardization in the industry [2] Industry Insights - Compressors are critical components of refrigeration systems, accounting for over 80% of the total energy consumption of these systems, yet their efficiency levels remain significantly below theoretical potential [2] - The process of establishing the two international standards faced challenges, including differing opinions from international experts during the proposal phase, but ultimately led to a successful consensus after extensive discussions and meetings [2][3] - The newly established standards fill a gap in international standards for performance evaluation in both positive displacement and centrifugal refrigeration compressors, providing a scientific and reasonable solution for energy efficiency evaluation in the global refrigeration compressor industry [3]
