Abstract: Compatibility tests were conducted on silicon steel sheets with two types of refrigerant oilrefrigerant media to evaluate the compatibility of the sheets, including separate hightemperature and lowtemperature compatibility tests on individual silicon steel sheet components. Based on the test results, it was determined whether the components meet the compatibility requirements. The compatibility differences between the two media and silicon steel sheets were compared based on the test results, providing a basis for determining the applicability of silicon steel sheets in different media.

Key words: silicon steel sheets, refrigerant oil, refrigerant, compatibility test
