Abstract
A refrigeration system is employed alternatively as an automatic ice-maker, and a device to automatically produce a supply of purified water by melting a portion of the ice produced in the ice-making operation. Separate sections of the condenser of the refrigeration system are selectively employed to provide heat to melt ice when the purified water supply is low and, alternatively, to reject heat when the purified water supply is sufficient but ice production is required.
