Hi Guys,

I'd like to hear your opinion about the floating condensing pressure. The purpose is to minimize the electric power consumption of the sum (Compressors + Condenser).

On a "conventional system" I would run the evaporative condenser fans inverter to delivery the maximum speed if the the condensing pressure is above the minimum acceptable pressure for the good feed of liquid separators. In this way it will always ensured the compressors will have the minimum possible power consumption and less wear (higher service intervals) and a little more of cooling capacity.

My opinion about that "miraculous" floating condensing set-point if it's not well done, if there is not measure of all important parameters and combine with them it could happen that we would spend more electric power. The problem is that when someone/Clients hear about floating set-point condensing they get very happy but don't know the real significance and future implications.
