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.
Claims28
A continuous-cycle absorption heating and/or cooling system comprising:
- a closed circuit comprising a condenser, an absorber, and an evaporator;
- a generator comprising:
- a firetube 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 firetube heat exchanger, and
- a supplemental heat exchanger in thermal communication with the exterior surface of the annulus and configured to contain a second fluid;
- and
- a heating device coupled to the supplemental heat exchanger and configured to heat the second fluid.
A co-fired generator comprising:
- a first heat exchanger;
- an annulus configured to contain a fluid, the annulus having an interior surface and an exterior surface, the interior surface in thermal communication with the first heat exchanger, and
- a second heat exchanger in thermal communication with the exterior surface of the annulus.
A method of heating a first liquid in a continuous-cycle absorption heating and cooling system, the method comprising:
- heating a first liquid in a generator having an annulus comprising an interior surface and an exterior surface;
- providing a supplemental heat exchanger in thermal connectivity to the exterior surface of the generator;
- and
- controlling the flow of a heat transfer medium to the supplemental heat exchanger to add heat to the firetube heat exchanger.
