Abstract
A refrigeration system employed as an icemaker, in which part of the ice so produced is stored in a bin, and in which, part of the ice is then melted to provide a supply of purified water in a container. In one embodiment convection flow of air conveys heat from the ambient room environment to the bottom of the ice bin to achieve this melting. In a second embodiment a convection flow of water is employed for this purpose. Controls are provided to automatically control melting, to maintain a predetermined level in the purified water container.
