ABSTRACT:
A method and apparatus for the transfer of heat at a lower temperature to another fluid at a higher temperature, using a rotary heat exchanger and circulating the two fluids through said heat exchanger wherein a third fluid is circulated. The third fluid is normally a gas, compressed within the rotor by centrifugal action, with accompanying temperature increase, and heat is removed from said third fluid to a second fluid during and after compression; heat is added to said third fluid from a first fluid during and after expansion. A fourth fluid may be also circulated within said rotor, for removing heat from said third fluid before and during early part of compression to increase the weight of said third fluid within the compression side of the said rotor, thus improving the circulation of said third fluid within said rotor. Said second fluid, said first fluid, and said fourth fluid may be either liquids or gases as desired, including water. Said third fluid may be carbon dioxide.
