ABSORPTION TYPE HEAT TRANSFER SYSTEM FUNCTIONING AS A TEMPERATURE PRESSURE POTENTIAL AMPLIFIER ABSTRACT An absorption type heat transfer and thermally powered temperature pressure potential amplifier system for storing energy by distilling and separating solute from a solution of the solute and a solvent at a low temperature, then amplifying and recovering the temperature and/or vapor pressure potential difference between the solute and the solution at a higher temperature in the form of heat transfer or its mechanical power equivalent. One working fluid is a solute having a low boiling point, the other a solution of the solute in a solvent having a high boiling point such that mutual solubility is poor at low tempera- tures as indicated by a small vapor pressure difference between solute and solution, and in which the vapor pressure difference between solute and solution greatly increases at higher temperatures. This permits the vapor pressure potential difference to be released in the form of mechanical work when vapor from separated solute is reabsorbed into solution in an absorber at the higher temperature. Similarly, an amplified temperature differ- ence exists between liquid solute and absorbent solution in a high temperature absorber when solute vapor passes freely into solution within the absorber. The working fluids are circulated in a closed cycle with an inter- mediate counter-flow heat exchange means for exchanging heat between separated solute and solution moving from the colder distilling means, and recombined warm solution returning to the colder distilling and separating means from the higher temperature absorber. This system utilizes low grade heat from natural sources.
