What is the method for checking refrigeration oil?
1 Answers
Refrigeration oil inspection methods can be divided into routine checks and professional inspections. For routine checks, simply observe the color - it should be clear, not cloudy, and free of sediment to be considered normal. If the oil appears emulsified or discolored, it indicates an abnormality. Professional inspections require specialized equipment to test the water content and cleanliness of the refrigeration oil. Refrigeration oil, also known as lubricating oil, is used to lubricate moving parts within refrigeration compressors. According to the standards set by the Petrochemical Industry Department, China produces five grades of refrigeration oil: No. 13, No. 18, No. 25, No. 30, and the enterprise standard No. 40.
