Freezing machine refers to the compressor used in compression refrigeration, because of the different conditions of use and compression working medium, it is different from the general air compressor. According to the working characteristics of the refrigerator and the specific requirements of the lubricating oil, the commonly used refrigerants are: freon, ammonia, lithium bromide, chloromethane, etc
Performance specifications of refrigerant oil
The main performance indicators of freezing oil are viscosity, freezing point, flash point, ignition point, turbidity point, acid value, oxidation resistance, moisture, mechanical impurities, ash, etc.
Introduction editing broadcast According to the working characteristics of the refrigerator and the specific requirements of the lubricating oil and the deployment of lubricating oil type It belongs to L-D group in the general classification of petroleum products Refrigerating machine According to the difference in the structure and working principle of the refrigerator, it is similar to the air compressor, and can also be divided into several different forms, such as piston type, screw type, centrifugal type. Refrigerating machine is one of the most important components of compression refrigeration equipment. The working medium of the refrigerator is the refrigerant which is responsible for the task of transferring heat in the refrigeration system. The commonly used refrigerants are: Freon, ammonia, lithium bromide, chloromethane, etc. According to its gasification temperature and chemical formula, Freon has a variety of fluorine 11 (R-11), fluorine 12 (R-12), fluorine 13 (R-13), fluorine 21 (R-21), fluorine 22 (R-22), fluorine 113 (R-113), fluorine 114 (R-114), fluorine 142 (R-142) and so on. The above refrigerant can be used in refrigeration systems with low pressure (condensation pressure less than 0.3-0.3MPa) high temperature (evaporation temperature greater than 0ºC), medium pressure (condensation pressure 1-2MPa), medium temperature (evaporation temperature 0-50 ºC) and high pressure (condensation pressure greater than 2MPa) low temperature (evaporation temperature less than -50ºC). |
