PROBLEM TO BE SOLVED: To efficiently perform auxiliary cooling corresponding to the change of cooling spots in a large space such as an exhibition hall. SOLUTION: In this combination 10 of a cooling machine and an indoor machine, the cooling machine 60 and the indoor machine 20 are connected by connecting parts 32a, 32b, 34a, 34b at night, a primary refrigerant cooled by a cooling part 61 of the cooling machine 60 is carried to a heat accumulation tank 22 of the indoor machine 20 through primary refrigerant circulating passages 78, 28, and the water filled in the heat accumulation tank 22 is frozen to make ice. The indoor machine 20 is separated from the cooling machine 60 at the connecting part, and only the indoor machine 20 is moved to the desired cooling spot by a caster 52 in the daytime. In the indoor machine 20, a secondary refrigerant is circulated in a secondary refrigerant circulating passage 42 connecting a condensing part formed in the heat accumulation tank 22 storing the ice, and an evaporator 40. The indoor air of high temperature is brought into contact with the evaporator 40 to be cooled, and returned to the room as the cold air for cooling. COPYRIGHT: (C)2005,JPO&NCIPI
