Abstract
Official abstract text for this publication.
This invention relates to using a guanidinium-based ionic liquid as an absorbent material in an absorption chiller. The invention provides an absorption chiller comprising a mixture of a refrigerant and an absorbent, and the absorbent is a guanidinium-based ionic liquid. A preferred refrigerant is water. This invention also provides a method for synthesizing N,N,N′,N′,N″,N″-hexamethylguanidinium acetate.
First claim
Opening claim text (preview).
What is claimed is: 1. An absorption chiller comprising an absorber compartment and a generator compartment, wherein both compartments comprise a mixture of a refrigerant and an absorbent, and the absorbent is a guanidinium-based ionic liquid, wherein the ionic liquid has an acetate anion. 2. The absorption chiller of claim 1 , wherein the refrigerant is water. 3. The absorption chiller of claim 1 , wherein the ionic liquid has a melting point of 400K or less. 4. The absorption chiller of claim 1 , wherein the ionic liquid has a kinematic viscosity lower than 25 centistokes. 5. An absorption chiller comprising an absorber compartment and a generator compartment, wherein both compartments comprise a mixture of a refrigerant and an absorbent, and the absorbent is a guanidinium-based ionic liquid, wherein the ionic liquid has a hexamethylguanidinium cation. 6. The absorption chiller of claim 5 , wherein the ionic liquid is hexamethylguanidinium acetate. 7. An absorption chiller comprising an absorber compartment and a generator compartment, wherein both compartments comprise a mixture of a refrigerant and an absorbent, and the absorbent is a guanidinium-based ionic liquid, wherein the ionic liquid has a hexaethylguanidinium cation. 8. The absorption chiller of claim 7 , wherein the ionic liquid is hexaethylguanidinium acetate. 9. The absorption chiller of claim 5 , wherein the refrigerant is water. 10. The absorption chiller of claim 5 , wherein the ionic liquid has a melting point of 400K or less. 11. The absorption chiller of claim 5 , wherein the ionic liquid has a kinematic viscosity lower than 25 centistokes. 12. The absorption chiller of claim 7 , wherein the refrigerant is water. 13. The absorption chiller of claim 7 , wherein the ionic liquid has a melting point of 400K or less. 14. The absorption chiller of claim 7 , wherein the ionic liquid has a kinematic viscosity lower than 25 centistokes.
