A cooling system comprises brine circulating paths (36, 35, 34, 37) between a chiller unit (30) and an ice thermal storage tank (31), and brine circulating paths (36, 40, 42, 37) between the chiller unit (30) and a brine/water heat exchanger (32), both of which paths are switched to each other at the time of heat accumulation in the ice thermal storage tank (31) and at the same time of cooling by the chiller unit (30). When both heat accumulation and cooling are to be simultaneously effected, brine is circulated through the paths (34, 37, 40, 32). The cooling system further comprises cooling water circulating paths (43, 44, 47, 32, 48, 50) between the ice thermal storage tank (31) and a cooling device (33), and cooling water circulating paths (48, 44, 47, 32) between the brine/water heat exchanger (32) and the cooling device (33), and single cooling of the ice thermal storage tank (31), single cooling of the chiller unit (30), single cooling of the chiller unit (30) at the time of heat accumulation of the ice thermal storage tank (31), and simultaneous cooling of the ice thermal storage tank (31) and the chiller unit (30) are switched to one another. |
