What is the floc or cloud point in refrigeration systems?

The floc or cloud point is defined as the temperature at which waxes begin to separate from the oil in a refrigeration system. This phenomenon is crucial in refrigeration because the formation of wax can clog filters, restrict oil flow, and impact the system's overall efficiency. Understanding this point helps in selecting appropriate lubricants and ensuring smooth operation under various temperature conditions.

In refrigeration systems, especially those using certain types of oils, it's important to avoid operating at temperatures lower than the cloud point to prevent potential operational issues. This knowledge is vital for technicians who strive to maintain optimal performance and reliability in refrigeration applications.
