ABSTRACT:
A method and apparatus for transferring heat by employing a rotating centrifuge to compress a gaseous first fluid with accompanying temperature increase and then transferring heat from said first fluid in its compressed state to a second fluid being circulated within said centrifuge in heat exchange relationship with said first fluid. After transferring said heat from said first fluid, said first fluid is allowed to expand within said centrifuge with accompanying temperature reduction. Said first fluid may then be passed out from said centrifuge, or said first fluid may be receiving heat within said centrifuge from a third fluid, being circulated in heat exchange relationship with said first fluid, after which said first fluid is again compressed within said centrifuge. Various gases may be employed as said first fluid, such as air, or halogenated hydrocarbons. Said second fluid is usually a liquid, such as water. The third fluid may also be water.
