The primary use of a jet ejector in a refrigeration system is to:

In refrigeration systems, a jet ejector primarily functions to raise settled oil that may be mixed with refrigerant. This is crucial for maintaining the proper operation of the system, as oil that settles can lead to inefficiencies or potential damage if not managed properly. The jet ejector creates a vacuum or low-pressure area that helps to lift the settled oil back into the system, ensuring that the oil circulates effectively and lubricates various components, such as compressors and pumps.

The correct understanding of this function highlights the importance of oil management in refrigeration systems. By utilizing a jet ejector to facilitate the movement of oil, the system can maintain optimal performance and efficiency, as oil plays a critical role in both lubrication and providing necessary sealing within mechanical components. Therefore, the role of the jet ejector goes beyond mere physical separation and highlights the integral nature of oil management in refrigeration efficiency.
