Outline of Final Research Achievements

We will develop the ice thermal storage system combined with sorption refrigerator to convert the unutilized heat into useful cooling energy for refrigeration. In the present system, ice slurry is produced in the evaporator of the sorption refrigerator. As the advantage of this system, we can transport ice slurry over a long distance by the pipe transportation. As the results the investigations, we showed the usefulness of the system because the efficiency of the system is high. We showed the operation condition to maximize the efficiency. Moreover, we clarified the technique to avoid the pipe blockage in the ice slurry flow. We can realize the continuous operation of the system by using the technique.
