Re: Digital scroll chiller
Dear colleague ,
My recommendation to control the capacity of a Chiller is to use the Hot Gas Bypass at the evaporator inlet . The problem with variable speed in Scroll compressors is lubrication at low speed .
I think your big problem is in the Shell-Tubes Evaporator that at low capacity the oil accumulates in the Evaporator and in the Condensation pressure that must be controlled . Regards ,Last edited by chemi-cool; 21-08-2018 at 07:29 PM.
