<p>A method of cooling a fluid medium in a heat exchanger by means of an endothermic heat of solution of crystals which are in contact with a heat exchanger in the base of a closed column where the solvent dissolves the crystals whereby to form a saturated solution which cools the heat exchanger, and applying heat to the saturated solution in an upper part of the column to vapourize the solvent and pass it to a condenser, the resulting super saturation causing recrystallization with the crystals sinking to the base of the column, the solvent condensate passing back to the base of the column to continue the endothermic solution of the crystals.</p> |
