Re: Optimization of the refrigeration plants operation
As an operator of a NH3 plant there are things that an operator can do to reduce energy costs, I have implemented many items that have small effects on the system as a whole. I have installed VFD's on condenser fans, and written plc code to run these fans on PID loops based on head pressure, also VFD's on evaporator fans in areas that can handle reduced air flow, fans can be set to reduce speed when temp in room is satisfied. Also optimize defrost, temp sensors on suction lines and programming that will trigger defrost when superheat from the evaportor starts to fall because the coil is icing over. There are many things that can help in these systems.
