Abstract
Abstract A conversion system is disclosed for evaporating salt water, for example, so as to produce fresh water. A quantity of salt water (liquid phase) is contained to receive heat and thereby evaporate a portion of such water to provide a gaseous phase. Heat is extracted from the gaseous phase resulting in condensed fresh water. The system transfers heat energy to a working fluid to power a compressor structure in a refrigeration cycle, and supplying heat to the liquid phase. Compressor structures are disclosed in the forms of an ejector and a turbine compressor. As disclosed, the same working fluid is employed in the power cycle and the refrigeration cycle. Specific structures are disclosed for obtaining greater efficiency including an arrangement for staging individual systems.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
156 words
An evaporation system, as for the conversion of salt water by heat energy, comprising: means for containing fluid to undergo conversion in a liquid phase and a gaseous phase and including means for removing condensed liquid from said gaseous phase; first working-fluid means in heat-transfer relationship with said liquid phase; second working-fluid means in heat-transfer relationship with said gaseous phase; heat source means for transferring said heat energy to said working fluid to provide high-temperature working fluid; compressor means connected to be activated by said hightemperature working fluid to provide pressurized working fluid; means for supplying said pressurized working fluid through said first working fluid means, then through said second working-fluid means to said compressor means; means for supplying working fluid from said first working-fluid means to said boiler means; means for securing a temperature difference between said first working fluid and said second working fluid; means for obtaining and maintaining said contained fluid under vacuum.
Claim 2
Dependent Claim
