994 Factory-engineered system control to manage a chiller plant room Thus optimising its performance and increasing its reliability by: J Optimal start-up, sequencing & staging of chillers J Matching chiller capacity to load demand iCM's main functionalities: Availability Determines whether chillers are available or not, based on: J Inputs from the chiller unit controllers J Modbus communication status J Pump status Sequencing Optimises the order in which available chillers are turned on and off depending on operating hours, energy efficiency, etc. Staging 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. Primary Pump control Primary evaporator and condenser pump control for dedicated and manifolded pumps thanks to iPM panel Secondary Pump Control Control of up to 12 secondary circuits thanks to iSM panel extension Cooling Tower Optimization Control and Optimization of Cooling Tower systems thanks to iCT extension modules. Remote Connection through Daikin on Site 24/7 monitoring and control of iCM plants through Daikin on Site cloud service. Why choose iCM? J Optimise performance J Increase reliability J Reduce energy costs J Reduce maintenance costs J Factory-engineered and tested J Remote control and monitoring.
