Apparatus comprising a freeze exchanger having an aqueous liquid feed stream inlet and an aqueous liquid stream outlet; a closed loop refrigeration system for supplying a refrigerant to the freeze exchanger for indirectly cooling aqueous liquid fed thereto; an ice storage tank; a conduit for withdrawing aqueous liquid, or a mixture of ice and aqueous liquid, from the freeze exchanger outlet and delivering it to the ice storage tank; a conduit for removing cold aqueous liquid from the ice storage tank and feeding it to a heat exchanger to cool fluid used for cooling purposes; and a conduit for removing warm aqueous liquid from the heat exchanger and feeding it to the ice storage tank, or to the freeze exchanger, or partially to both. A method of cooling making use of the apparatus is also disclosed.
