Abstract

A process for cooling liquids wherein a coolant is cooled in a chiller during off-peak electrical demand periods, then directed to a first insulated storage vessel where it is stored until off-peak electrical demand periods have ended. During peak electrical demand periods, the coolant flows from the first insulated storage vessel to a flat plate heat exchanger, where a flow of liquid to be cooled, entering through a second conduit, is cooled. The cooled liquid exiting the heat exchanger is directed to a second insulated storage vessel where little or no further cooling of the liquid will be necessary during peak electrical demand periods.
