MAIN PLANT COOLING OPERATIONS The operating regimen of the main cooling plant is just as important as the equipment itself. Year-round: The ice storage system is charged every night so that it can be used as the first cooling strategy regardless of the time of year. Normal summer: In addition to the ice storage system, the chiller with a variable frequency drive (VFD) will be brought online and modulated to the required demand. Peak/hot summer: The dedicated ice chiller with no VFD will be brought online at full capacity, with the VFD chiller modulating as required to meet the remainder of the load. SAVINGS Chilled water system: The Belimo energy valve project combined with the installation of VFDs on the chilled water pumps means that the cooling plant can operate on a low flow, low temperature (LFLT) control strategy, Main cooling plant rather than on a high flow, high temperature (HFHT) control strategy.
