ABSTRACT:
A method and apparatus for transport of heat from a low temperature heat source into a higher temperature heated sink, using a compressible working fluid compressed by centrifugal force within a rotating rotor with an accompanying temperature increase. Heat is transferred from the heated working fluid into the heat sink at higher temperature, and heat is added into the working fluid after expansion and cooling from a colder heat source. Cooling is provided within the rotor to control the working fluid density, to assist working fluid circulation. The rotor has outward and inward extending working fluid passages for circulation therein, and heat is provided by a heat source fluid within its own heat exchanger, and heat is delivered into a heated fluid circulating within its own heat exchanger. Cooling is provided by circulating a cooling fluid within its own heat exchanger; alternately, the heated fluid may also serve as the cooling fluid if desired, before being heated. A regenerative heat exchanger is also provided exchanging heat between two streams of the working fluid within the rotor.
