Abstract
A method and apparatus for melting ice incidental to a freezing process for water desalination. Mechanical energy otherwise required to pump super heat in the compressed refrigerant vapor is conserved and rate of ice melting in the melter-washer reduced by providing an auxiliary blower for recycling uncondensed refrigerant vapor around the melter and providing for removal of net uncondensable refrigerant vapor to the secondary compressor from a point between the freezer and melter.
