What does POE stand for in refrigeration technology?

In refrigeration technology, POE refers to Polyolester. This is a type of synthetic lubricant that is commonly used in refrigeration and air conditioning systems, particularly with refrigerants that have low global warming potential or are hydrofluorocarbons (HFCs). Polyolester oils have excellent solubility with many refrigerants and play a crucial role in maintaining the efficiency and effectiveness of the system.

The use of Polyolester oils is significant because they can provide better lubrication than mineral oils, especially in systems that operate at high temperatures and with refrigerants that have a high degree of oil miscibility. Proper lubrication is essential for preventing wear and tear on compressor components, ultimately leading to longer equipment lifespan and optimal performance.

The other options such as Polyolefin Ester, Partial Oil Emulsion, and Polyethylene Oil Energy do not accurately represent the established terminology and applications in refrigeration technology related to lubricants. Polyolester is the widely recognized and utilized term in this context.
