METHOD OF HEATING AND COOLING FLUID MEDIUM Russian patent published in 2004 - IPC

FIELD: heating engineering, particularly combined heating and refrigeration systems.

SUBSTANCE: method involves introducing fluid medium to be cooled or heated in through channel, successively cooling or heating fluid medium into through channel in at least two stages. Through channel is divided into cooling or heating stages having equal lengths. Temperature of each stage increases rapidly from the first stage to following stage in proportion to medium heating or decreases rapidly in proportion to medium cooling. Fluid medium to be cooled or heated is fed in through channel tangentially at the angle of 45^o - 90^o to generator of inner through channel surface in point of fluid medium introduction.

EFFECT: increased efficiency of medium heating or cooling processes, reduced power consumption, usage of two or more multistage heat or cold generators.
