ABSTRACT:
A thermal engine is disclosed which is operable as a heat pump, refrigerator, or air conditioner. Vaporized working fluid from a first evaporator, which extracts heat from elements desired to be cooled, is fed to a first region of an osmotic pump which also has a second region containing a solution of the working fluid and a preselected solute, the second region being separated from the first region by a membrane permeable to the vaporized working fluid but not to the solute. A second evaporator, which may be driven by waste heat, is operatively coupled to the second region of the osmotic pump by means of a counterflow heat exchanger having a first path for conveying relatively dilute solution from the second region of the osmotic pump to the second evaporator and a second path for conveying relatively concentrated solution from the second evaporator to the second region of the osmotic pump. Output heat from the thermal engine is obtained from a condenser which condenses vaporized working fluid from the second evaporator. The condensed working fluid undergoes constant enthalpy expansion, after which it is returned to the first evaporator.
