<p>A method of chilling, cooling or likewise refrigerating a product with the aid of the cold content of a condensed gas, wherein the product, preferably in a gas or liquid state, is caused to pass at least one product-cooling heat-exchanger (20). According to the invention, the condensed gas is vaporised in at least one evaporation heat-exchanger (30) and the vaporised gas is delivered to the product-cooling heat-exchanger for cooling the product therein. The gas heated by the product in the product-cooling heat-exchanger is then returned to the evaporation heat-exchanger for vaporisation of the condensed gas therein. The invention also relates to an arrangement for use in carrying out the method.</p> |
