Abstract
A method and apparatus for controlling the growth of the solid phase of a substance from around a cooling mechanism, such as the growth of an ice pack in a water cooling system, while also minimizing chances of inaccurate control by referencing the apparent resistance of the liquid that is actually in the system rather than a standard value. The method also provides for a dead-band by monitoring the resistance of the liquid at two roughly adjacent locations.
