PURPOSE: To obtain a cooling device capable of being operated with a substantially constant efficiency under a load out of peak or a peak load by a method wherein the same brine is employed commonly in a freezing heat exchanger, an ice storing tank and heat exchanger.
CONSTITUTION: The size of the ice storing tank 40 may be a size insufficient for supplying the total cooling load of an installation 80. Cooled fluid is taken out of the heat exchanger 64 through a conduit 68 and is supplied to the coil 78 of the installation 80 to provide necessary cooling. All or a part of the heated brine in the conduit 70 is supplied to the conduit 90 to send it to the top of the freezing heat exchanger 10. The brine may be cooled without forming ice during flowing through the freezing heat exchanger under operation. The cooled brine is taken out of the freezing heat exchanger through the conduit 30 to supply it to a receiving tank 32 and is taken out of the same heat exchanger through the conduit 100 to supply it to the bottom of the ice storing tank 40. The cooled brine, taken out of the tank 40 through the conduit 58, is sent by a pump 60 to the conduit 62 to supply it into the heat exchanger 64 and is utilized for cooling.
