ABSTRACT:
A method and apparatus for transferring heat from a first fluid which is normally gaseous to a second fluid which is normally a liquid, by using a rotating rotor with passages for said first fluid extending from rotor center outward and with passages for said second fluid also extending outward within said rotor with said two fluids being in heat exchange relationship within said rotor with heat another transferred from said first fluid to said second fluid, wherein said first fluid temperature is increased by compressing said first fluid within said rotor. Said two fluids are then returned in separate passages to the center of said rotor and discharged; said first fluid will leave said rotor colder than it entered and said second fluid will leave said rotor warmer than it entered. In one form of the invention, said rotor is mounted within a sealed casing with entry and exit for first fluid to said casing, and a heat exchanger for adding heat is provided. Also, in anothe form of the invention, nozzles are added to rotor walls for discharging said first fluid backward thus recovering some work. Also, a means is included for reducing external friction on rotor.
