The economic aspects of an ice storage system employing supercooled water were compared with those of a chilled water system. In this analysis, the characteristics of the thermal storage tank and the system-COP were selected as technological factors, that have particular relevance to the economic issues at introduction of tharmal storage systems.
The following results were obtained :
(1) The cooling rate of the ice storage system was comparable with the rate of a chilled water storage system.
(2) The cooling rate of the ice storage system was not hardly influenced by the cost of thermal storage tank.
(3) In the hybrid thermal storage system, the ice storage system could surely satisfy the requirement for large peak shift.
