What does the floc point indicate in a refrigerant system?

The floc point in a refrigerant system specifically refers to the temperature at which wax or other solid contaminants begin to separate from the oil used in the refrigeration process. This separation can adversely affect the system's performance and efficiency. When the temperature falls below the floc point, wax crystals can form, leading to clogging in filters and other parts of the system. Remaining aware of the floc point is essential for proper maintenance and operation of refrigerated systems, as it helps in avoiding operational issues linked to the separation of wax.
