Outline of Final Research Achievements

Fundamental study on LiBr/water absorption heat pump (AHP) using LiBr fine particle crystal slurry was performed to develop an innovative recovery system of exhausted heat at a middle temperature level, that is working in heating-up and refrigeration modes with a heat storage function.
The slurry inhibits the solution from diluted in an interface between liquid and gas phases due to steam absorption, and allows the AHP operation under as high as concentration of saturation solubility. This performance contributes to significant improvement of steam absorption rate and generation of much higher temperature than a crystal-free uniform solution in a heating-up mode. The thermodynamic equilibrium analysis reveals that the slurry obtains also greater heat storage capacity than conventional phase change media. A heat storage type of hybrid AHP cycle is proposed to yield simultaneously high temperature above 120 °C and refrigeration at 7 °C recovering heat at a 80 °C level.
