Abstract
A co-fired generator for use in a continuous-cycle absorption heating and cooling system may provide heat to the interior of an annulus chamber from a first heat exchanger, such as a firetube heat exchanger, supplemented by heat to the exterior of the annulus chamber from a second heat exchanger containing fluid heated by an external source. Some embodiments may circulate fluid heated in a solar-heated collector through the second heat exchanger. Other embodiments may route exhaust gas from a combustion engine through the second heat exchanger. The second heat exchanger may be provided with a plurality of fins to increase the surface area available for thermal transfer between the heated fluid and the annulus chamber.
Claims26
A continuous-cycle absorption heating and/or cooling system comprising:
- a closed circuit comprising a condenser, an absorber, and an evaporator;
- a co-fired generator comprising:
- a first heat exchanger;
- an annulus configured to contain a first fluid, the annulus having an interior surface and an exterior surface, the interior surface in thermal communication with the first heat exchanger and positioned to transfer heat to the annulus via the interior surface;
- a second heat exchanger in thermal communication with the exterior surface of the annulus and positioned to transfer heat to the annulus via the exterior surface;
- an inlet coupling the second heat exchanger to a heating device for providing a heated second fluid to the second heat exchanger in order to heat the first fluid from the exterior as the first heat exchanger heats the first fluid from the interior;
- and
- a controller configured to circulate the heated second fluid through the second heat exchanger when a temperature of the heated second fluid is above a temperature of the exterior surface of the annulus;
- and
- wherein the heating device is configured to heat the second fluid.
