Objective
THE AIM OF THE STUDY IS TO PROVE THE FEASIBILITY OF A THERMOCHEMICAL HEAT PUMP SYSTEM ABLE TO STORE ENERGY AND RESTORE IT UNDER HEAT AND COLD. THIS NEW SYSTEM USES GRAPHITE INTERCALATION COMPOUNDS WHICH IMPROVE THE THERMAL CONDUCTIVITY AND THE REVERSIBILITY.
This work contributes to the study of the action of ammonia on graphite-metallic chloride intercalation compounds. The reaction has been followed in situ in real time by neutron diffraction. The formation of ammoine microcrystals within a graphite crystalline network has been observed. The products obtained may be assimilated into inclusion compounds of graphite. The texture of this new material is particuarly suited to the transfer of material and heat at the particle level. To do this, the new compound is proposed in place of ammoniacate alone in the field of thermochemical energy conversion processes. The reactants are placed on a fixed bed in a solid-gas reactor. Video studies of the reactions have shown satisfactory results and suggest a bright future for the development of this type of product.
DESCRIPTION
THE PROJECT INVOLVES THE STUDY OF A NEW CHEMICAL HEAT PUMP SYSTEM THAT IS ABLE TO STORE AND THEN RELEASE ENERGY IN THE FORM OF HIGH OR LOW-TEMPERATURE HEAT. THE PRINCIPLE IS BASED ON A REVERSIBLE REACTION OF THE TYPE:
SOLID S + GAS G 1/2 SOLID P, IN WHICH SOLIDS S AND P ARE GRAPHITE INSERTION COMPOUNDS CONTAINING METALLIC SALTS AND GAS G IS AMMONIA NH3. THIS REACTION HOLDS GREATER APPEAL WITH REGARD TO THE QUANTITY OF REACTION HEAT STORED, THE REACTION KINETICS AND ITS REVERSIBILITY. THE FINAL ACCUMULATOR FOR THE HEAT (SOLAR OR OTHER) WOULD RELEASE THE HEAT IN ACCORDANCE WITH THE HEAT PUMP PRINCIPLE. THE SYSTEM COULD ALSO BE USED TO REFRIGERATE. IN BOTH CASES STORAGE COULD BE FOR AN UNLIMITED PERIOD.
