How Chiller Plant Economization Works
The chilled water loop that feeds multiple chilled water-based CRAC units uses cold outdoor
temperatures to cool the chilled water loop, effectively reducing pump operation.
The chilled water loop that feeds multiple chilled water-based CRAC units uses cold outdoor
temperatures to cool the chilled water loop, effectively reducing pump operation.
Full economization hours are dependent upon the outdoor wet bulb temperature,
the approach of the cooling tower and heat exchanger, and the chiller water supply
temperature. Partial economization hours are dependent upon the factors listed above, as
well as the chilled water return temperature.
