According to the differences in structure and working principle of refrigerators, they are similar to air compressors and can also be divided into several different forms such as piston type, screw type, centrifugal type, etc. The freezer is one of the most important components of compression refrigeration equipment.

　　The working medium of a refrigerator is the refrigerant responsible for transferring heat in the refrigeration system. Commonly used refrigerants include Freon, ammonia, lithium bromide, chloromethane, etc. Among them, Freon has different gasification temperatures and chemical formulas, such as 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), etc. The above refrigerants can be used in low-pressure (condensation pressure less than 0.3-0.3MPa), high-temperature (evaporation temperature greater than 0 ℃), medium pressure (condensation pressure 1-2MPa), medium temperature (evaporation temperature 0-50 ℃), and high-pressure (condensation pressure greater than 2MPa), low-temperature (evaporation temperature less than -50 ℃) refrigeration systems.

Main functions of refrigeration oil

　　(1) Lubricate the friction surface to completely separate it with an oil film, thereby reducing frictional work, frictional heat, and wear

　　(2) The flow of refrigeration oil carries away frictional heat, keeping the temperature of friction parts within the allowable range

　　(3) Fill the sealing area with oil to ensure sealing performance and prevent refrigerant leakage

　　(4) The movement of oil carries away the debris generated by metal friction, playing a role in cleaning the friction surface

　　(5) Provide hydraulic power for the unloading mechanism
