Title:
HIGH ENERGY EFFICIENCY WATER DESALTING METHOD AND APPARATUS
Document Type and Number:
Japanese Patent JPS5415468
Kind Code:
A
Abstract:
Process to desalinate water, which comprises the operations of: feeding salt water to an enclosure that defines a zone of evaporation maintained at subatmospheric pressure; boiling the water in the evaporation zone and allowing the water vapor to pass a condensation zone; condensing the steam in the condensation zone and collecting desalinated water from it, whose improvements include: providing the heat of vaporization by transmitting heat from a heat sink to the evaporation zone and by transmitting condensation heat from the condensation zone to a low temperature dissipater, at least one of the heat transmissions being effected through a closed system in which a refrigerant is condensed and cyclically evaporated, and in which the proportion of energy transmitted as heat to energy required to effect the transmission, is at least 15.
