PROBLEM TO BE SOLVED: To downsize an ice machine and improve a performance factor. SOLUTION: A freezing circuit 5 comprises a compressor 1, a first condenser 2, an expansion valve 3 and an ice machine 4. An auxiliary freezing circuit 6 is connected to the freezing circuit 5 parallel with the ice machine 4 and the expansion valve 3 from the output side of the condenser 2 to an intermediate port 1a of the compressor 1. An ice heat storage tank 12 is connected to the ice machine 4 to store generated ice. A skeleton heat-storage equipment 9 for storing cold heat in floor slabs W by blowing cold air against the floor slab W and a second condenser 10 are provided, and a coolant is allowed to make a natural circulation flow between the heat-storage equipment 9 and the condenser 10. Binotherm(R) solution-containing ice is supplied from the ice heat storage tank 12 to the condenser 10 at night. Binotherm solution which has been heat exchanged in the condenser 10 is supplied to a heat exchanger 7 to be cooled, and the solution is supplied to the ice machine 4 to perform ice heat-storage and skeleton heat-storage.
