Requirements for the use of freezing oil

Requirements for the use of freezing oil Due to the different use occasions and refrigerants, the choice of refrigeration oil for refrigeration equipment is also different. The requirements for freezing oil< are as follows: 1. Freezing point: The temperature at which the freezing oil is cooled to stop flowing under the experimental conditions is called the freezing point. The freezing point of the refrigeration oil used in refrigeration equipment should be as low as possible (such as R22 compressors
