PROBLEM TO BE SOLVED: To increase a cold storage amount while suppressing the excessive lowering of a temperature of a heat medium circulation apparatus.SOLUTION: A cooling device comprises: a compressor 21 which sucks a refrigerant of a refrigeration cycle 20 and discharges it; a pump 11 which sucks a heat medium and discharges it; a chiller 12 which cools the heat medium by heat-exchanging the refrigerant and the heat medium; a heat medium circulation apparatus 14 in which the heat medium cooled by the chiller 12 circulates; and heat medium temperature adjustment means 19, 40 which adjust a temperature of the heat medium so that the temperature of the heat medium cooled by the chiller 12 becomes lower than the temperature of the heat medium in the heat medium circulation apparatus 14. Concretely, the heat medium temperature adjustment means 19, 40 adjust the temperature of the heat medium by adjusting a flow rate of the heat medium flowing into the heat medium circulation apparatus 14.SELECTED DRAWING: Figure 1 |
