ARLINGTON, Va. - The Air-Conditioning and Refrigeration Technology Institute (ARTI) has released a final report on a research project titled "Variable Primary Flow Chilled Water Systems: Potential Benefits and Application Issues."
To measure the energy use and economic benefits of variable primary flow chilled-water systems, ARTI conducted a study that compared variable primary flow chilled-water system energy use with that of other common system types, including constant flow/primary-only chilled-water systems, constant primary flow/variable secondary flow chilled-water systems, and primary/secondary chilled-water systems with a check valve installed in the decoupler.
