Claims
- 1. In a rotary heat exchanger wherein a compressible working fluid is circulated within a rotor outwardly in a first passage and inwardly toward center of rotation in a second passage, with the inward ends and outward ends of said passages connected by passage means to allow the circulation of said working fluid, and wherein a heat delivery heat exchanger is provided to remove heat from the working fluid during and after compression, and a heat source heat exchanger is provided to add heat into the working fluid during and after expansion, the improvement comprising:
- a. a regenerative heat exchanger provided to exchange heat between two streams of the working fluid, with the working fluid stream leaving said heat delivery heat exchanger being in heat exchange relationship with the working fluid stream entering said heat delivery heat exchanger and being upstream of said heat delivery heat exchanger, and wherein a cooling means is provided to remove heat from said working fluid downstream of said heat source heat exchanger.
- 2. The rotary heat exchanger of claim 1 wherein said heat delivery heat exchanger is provided with a heated fluid circulated within said heat delivery heat exchanger.
- 3. The rotary heat exchanger of claim 1 wherein said heat source heat exchanger is provided with a heat source fluid circulated within said heat source heat exchanger.
- 4. The rotary heat exchanger of claim 1 wherein said cooling means comprises a stationary cooling heat exchanger for removal of heat from said working fluid, into a coolant circulated within said cooling heat exchanger.
- 5. The rotary heat exchanger of claim 1 wherein said cooling means is a cooling heat exchanger carried by said rotor for removal of heat from said working fluid.
- 6. The rotary heat exchanger of claim 1 wherein said heat source heat exchanger is provided with a heat source fluid circulated within said heat source heat exchanger and wherein said heat source fluid is a gas at least when entering said heat source heat exchanger entry passages.
