Abstract
An absorption system powered by low temperature heat for producing at least one of refrigeration and power is disclosed, wherein a low-pressure drop heat reclaimer 1 reclaims heat from the source into a heating agent, which in turn supplies heat to the absorption cycle desorber 5 via internal coils 7. The extra temperature differential normally present in closed cycle heating systems is avoided by using the absorption working fluid as the heating agent, in an integrated system.
Claims12
An apparatus for converting thermal energy into at least one of refrigeration, cooling, and shaft power, comprising:
- a) an absorbent solution comprised of sorbate plus absorbent;
- b) a desorber comprised of:
- i) an entry port for sorbate-rich liquid absorbent;
- ii) a means for separating said sorbate-rich absorbent into sorbate vapor and sorbate-lean absorbent;
- iii) an exit port for said sorbate vapor;
- and
- iv) an internal heat exchanger which has an entry port in communication with said sorbate-lean absorbent;
- c) an external heat exchanger which is in thermal contact with said thermal energy;
- d) a first flowpath from an exit port of said internal heat exchanger to said external heat exchanger;
- and
- e) a second flowpath from said external heat exchanger to said desorber.
