ABSTRACT:
A refrigeration system provides a supply of purified ice pieces by freezing flowing water on an icemaking plate and melting some of the ice pieces to provide a supply of purified water. The system is combined with a household refrigerator to utilize a common compressor, evaporator and condenser. Alternative arrangements are provided for defrost of the evaporator by hot gas bypass, or by electrical heating elements. Individual ice pieces can be formed separately by spacing of the contact points where the evaporator piping meets the ice-forming surface, or by dividing the ice forming surface into separate ice forming cavities, with a plastic mask.
