A method for refrigerating fresh products, wherein a refrigeration system provided with an outlet device for transporting a first and a second airflow (3, 4) is used, the outlet device being provided with: (a) a first through-opening for the first air flow to flow out of the refrigeration system to a first zone extending outside of the outlet device, and a second through-opening for the second air flow to flow out of the refrigeration system to a second zone extending outside of the outlet device, wherein the outlet device is provided with a separation element situated between the first and the second opening (21, 22) for directing the first and the second air flow (3, 4) to the first and second zone (7, 8), respectively, or: (b) a first through-opening for sequentially allowing the first air flow to flow out of the refrigeration system to a first zone extending outside of the outlet device, and the second air flow to flow to a second zone extending outside of the outlet device, wherein the outlet device is provided with a separation element for directing the first and the second air flow (3, 4) to the first and second zone (7, 8), respectively; characterized in that the method comprises the steps of: - generating the first and the second air flow (3, 4), wherein the first air flow has a first temperature and a first air humidity, and the second airflow has a second temperature and a second air humidity, - conditioning the first and the second air flow (3, 4), such that the first temperature is lower than the second temperature and that the first air humidity is lower than the second air humidity, - allowing the first air flow to flow out of the outlet device to the first zone extending outside of the outlet device, and allowing the second air flow to flow out of the outlet device to the second zone extending outside of the outlet device, such that the first zone extends over and at least partially adjacent to the second zone for mixing air present in the first zone with the air present in the second zone, which mixing takes place in a third zone extending downstream relative to the first and the second zone (7, 8), the products being refrigerated in the third zone. (a) a first through-opening for the first air flow to flow out of the refrigeration system to a first zone extending outside of the outlet device, and a second through-opening for the second air flow to flow out of the refrigeration system to a second zone extending outside of the outlet device, wherein the outlet device is provided with a separation element situated between the first and the second opening (21, 22) for directing the first and the second air flow (3, 4) to the first and second zone (7, 8), respectively, or: (b) a first through-opening for sequentially allowing the first air flow to flow out of the refrigeration system to a first zone extending outside of the outlet device, and the second air flow to flow to a second zone extending outside of the outlet device, wherein the outlet device is provided with a separation element for directing the first and the second air flow (3, 4) to the first and second zone (7, 8), respectively; characterized in that the method comprises the steps of: - generating the first and the second air flow (3, 4), wherein the first air flow has a first temperature and a first air humidity, and the second airflow has a second temperature and a second air humidity, - conditioning the first and the second air flow (3, 4), such that the first temperature is lower than the second temperature and that the first air humidity is lower than the second air humidity, - allowing the first air flow to flow out of the outlet device to the first zone extending outside of the outlet device, and allowing the second air flow to flow out of the outlet device to the second zone extending outside of the outlet device, such that the first zone extends over and at least partially adjacent to the second zone for mixing air present in the first zone with the air present in the second zone, which mixing takes place in a third zone extending downstream relative to the first and the second zone (7, 8), the products being refrigerated in the third zone. - generating the first and the second air flow (3, 4), wherein the first air flow has a first temperature and a first air humidity, and the second airflow has a second temperature and a second air humidity, - conditioning the first and the second air flow (3, 4), such that the first temperature is lower than the second temperature and that the first air humidity is lower than the second air humidity, - allowing the first air flow to flow out of the outlet device to the first zone extending outside of the outlet device, and allowing the second air flow to flow out of the outlet device to the second zone extending outside of the outlet device, such that the first zone extends over and at least partially adjacent to the second zone for mixing air present in the first zone with the air present in the second zone, which mixing takes place in a third zone extending downstream relative to the first and the second zone (7, 8), the products being refrigerated in the third zone.
