How to solve the problem of poor oil return of screw chiller

1. What is the cause of the poor oil return of the screw chiller? 　　 Generally speaking, the reason for the poor oil return of the screw chiller is mainly due to the phenomenon of the gas mixture of lubricating oil and refrigerant during the operation. Specifically, in the operation of the refrigeration system, encountering the miscibility of the refrigerant and the refrigerator lubricating oil will cause the lubricant in the refrigeration compressor to run and the refrigerant will be discharged into the condenser in the form of gas mist and droplets.
