Abstract
A thermal energy differential power conversion apparatus. A parallel series of vessels hold a working liquid at a level intermediate the upper and lower ends of the vessel. A first tube operatively engages the uppers ends of the vessels for carrying a liquid above the boiling temperature of the working liquid. A second tube is in contact with the liquid in each vessel for carrying a liquid at a temperature below the boiling temperature of the liquid. An outlet on each vessel directs heated working liquid under pressure from each vessel to a chamber for vaporizing the liquid and directing the resulting high pressure vapor to a work producing station, such as s scroll compressor operated in reverse as an expander. An inlet tube conveys low pressure vapor from the work producing station back to the vessels. Valves are provided in the tubes for selectively heating the liquid in each vessel to produce the high temperature, high pressure, liquid and for cooling the vessel to condense the returning low pressure vapor.
