ABSTRACT:
A chill water system combining a storage vessel 10, a multiplicity of ice encapsulating units 11 contained in the vessel and a chiller system 60. The storage vessel contains a volume of glycol and water solution having a freezing point of about twenty six degrees F. The ice encapsulating units 11 comprise sealed containers filled with a deionized water and having a volume of powdered cholesterol therein to serve as an ice nucleating agent to lower the initial ice formation temperature of the unit. The containers have imperfect geometric shape and deformable wall structures to permit an increase in enclosed volume as said water therein freezes. Chiller system 60 is operatively associated with the vessel and cools the glycol and water solution to about twenty six degrees to freeze the water in the containers 11. A topping tank 90 and an inventory tank 93 receive liquid from the storage vessel 10 as the ice encapsulating units 11 freeze and expand in volume.
