iCM intelligent Chiller Manager
Daikin Applied iCM intelligent chiller manager for chiller plant rooms
Whatis iCM, the intelligent chiller manager?
Factory-engineered system control to manage a chiller plant room
Thus optimising its performance and increasing its reliability by:
- Optimal start-up, sequencing & staging of chillers
- Matching chiller capacity to load demand
iCM's main functionalities:
Determines whether chillers are available or not, based on:
- Inputs from the chiller unit controllers
- Modbus communication status
- Pump status
Optimises the order in which available chillers are turned on and off depending on operating hours, energy efficiency, etc.
Calculates energy-optimal stage-up/stage-down of the chiller by determining the increased capacity demand by capacity control, compensation of temperature and rotation. This function aims at providing the most energy-efficient combination of chillers on a continuous basis.
Stopping Last Chiller/Recycling
Captures a rise in demand when the last chiller is staged down, by operating the pump dedicated to the next ON chiller at a minimum VFD frequency.
Min/Max Operating Chiller Setting
Ensures that the number of operating chillers always stays within a certain range, regardless of changes in demand.
