METHOD OF CONTACTLESS TRANSFER OF HEAT Russian patent published in 1997 - IPC

FIELD: heat transfer systems; separation of solutions into components by sublimation with no consumption of thermal energy and practically with additional facilities required for realization of this method. SUBSTANCE: low-boiling fraction of solution of is used as intermediate heat-transfer agent by "thermal tube" principle. This fraction is boiled away from solution near wall through which heat is delivered to solution from working body and is condensed on wall through which heat is transferred to another working body; separated fractions of solution may be changed by solution proper through heat exchangers where fractions and solutions run through cooled and heated chamber in counter-flow. Fixed gases dissolved in solution may be sucked constantly or solution may be preliminarily degassed by letting if flow by gravity to evacuated system, for example to heating vacuum-vapor system. EFFECT: higher efficiency. 3 cl
