What is the consequence of a restricted jet ejector raising oil mixed with refrigerant?

The consequence of a restricted jet ejector raising oil mixed with refrigerant is primarily related to insufficient head lift for the oil. In systems that utilize jet ejectors, they rely on proper flow dynamics to function efficiently. When there is a restriction, the jet ejector may not generate enough pressure to lift the oil effectively.

This insufficient head lift can lead to various operational issues within the refrigeration system. Oil is essential for lubricating the compressor and other components; if the oil is not properly lifted and fed back to the compressor, it can result in inadequate lubrication. Consequently, this could cause increased wear and tear on the compressor and other parts, potentially leading to system failure.

In contrast, optimal performance would require that both refrigerant and oil circulation is maintained without restrictions. Full vaporization of oil is not necessary or typically desired in refrigeration systems; rather, it is important to maintain a proper oil return. The implications of functioning without issues are also diminished, as a restriction in the ejector indicates that there will likely be compromises in system performance and reliability.
