Abstract: Studies on the evolution of the GB/T 15765, hermetic motor-compressors for room conditioners, and expounds the continuous tracking of the industry and technological development process, so as to maintain the advanced nature of the standard. This paper focuses on the origin of the standard and the main technical content of the specification. This paper sorts out the technical requirements of the key indicators, such as the change of various types of compressors, the performance coefficient and other key indicators, the requirements of the variable frequency compressor, and the partition of the cylinder volume. This paper summarizes the social benefits of the standard for the development of the industry, and puts forward some suggestions for the revision of the standard, so as to reflect the green, energy-saving and comfortable content of the standard.
