Abstract
A method and apparatus for the generation of cooling or heating by using a centrifuge type heat exchanger wherein the refrigerant during heat addition undergoes a pressure increase. The apparatus where heat is added is a rotary heat exchanger with the refrigerant being within the heat exchanger and rotating with it, and the air which is releasing heat is outside of the heat exchanger in a stationary casing. Stationary or rotary heat exchanger may be used for heat rejection by the refrigerant. By reversing the air connections, one can also use the device for heating room air in air conditioning applications, while the air circulating around the heat exchanger is outside air. Refrigerant fluids for this device may be the usual fluids used for refrigeration, such as air, halogenated hydrocarbon, ammonia and others.
Claims2
A thermodynamic method comprising:
- a. passing a fluid through a pressure reducing expansion valve;
- b. subsequently vaporizing said fluid in a continuously rotating evaporator-compressor comprising alternate compression-expansion steps with simultaneous addition of heat and accompanying pressure increase.
