The InfoScan Chilled-Water Reset application provides a convenient way to control chilled-water systems in such a way that they provide the warmest water that still satisfies the worst case load, saving valuable energy. Each load’s cooling needs are determined and the chilled-water setpoint is programmatically adjusted to minimally meet the requirements of the most demanding load.
When the individual loads using chilled water are not monitored, the application can provide a control scheme which maintains a constant chilled-water return temperature.
To implement chilled-water reset the application uses a library of blocks which perform specific functions. By assembling different control schemes from these blocks, almost any system configuration can be controlled.
