Abstract
The brine tube of an ice thermal storage tank has a surface enhancement which provides nucleation sites for ice formation, and reduces the need to superchill the water. The tubing enhancement comprises a multiplicity of solid mineral particles distributed evenly over its surface. The particles have jagged, multi-faceted surfaces which adsorb air. When the brine in the tube cools the water to the freezing point, the adsorbed air coalesces into air bubbles that serve as nucleation sites. This permits freezing to initiate a temperature of about 31.5.degree. F.
