Features refrigerated containers refrigerated containers can be used to transport a variety of means of transportation from the origin to the point of sale, and "country to country" direct transport under certain conditions, can be used as movable type refrigerator that use can FCL lifting, handling efficiency High transportation costs are relatively low. Load capacity utilization high, flexible scheduling operations, the use of economic and strong. The new refrigerated container structure is more reasonable and advanced technical performance, have broad applicability. Refrigerated containers - General requirements for the use of refrigerated container Reefer ⒈ should be checked after loading the original quality of refrigerated or frozen goods, and are described in the manifest. ⒉ the packing process, should be strictly loading stacking principle, to avoid a short circuit caused by cold air cooling imbalances, reduce the cooling efficiency of the refrigeration apparatus. When ⒊ frozen goods long-distance transport, inside the set temperature and the actual temperature difference should not exceed 3 ℃. If delivery of cooling goods, its temperature error should be less than 0.5 ℃, preferably not more than 0.25 ℃. ⒋ container transport fresh fruit, vegetables, etc., should be to open a new outlet, for ventilation. But transporting frozen goods, the new outlet should be closed. ⒌ when transporting cartons of cooling goods, should be based on the outdoor temperature and humidity conditions, timely ventilation, keep the air inside the drying, the outer surface of the box to prevent condensation. Refrigerated containers - cool thermal performance refrigerated containers normally used for transporting frozen goods temperature should not be higher than -18 ℃. Typically foot refrigerated containers, with an average cooling rate of 31.3 ℃ / h (empty); but after loading, cargo due to the large heat capacity, will greatly slow down the cooling rate, and sometimes reaches the set temperature requirements needed 15-16h. If you purchase the temperature is high, the temperature required to achieve the set 2-3d. Refrigerated container box temperature rise, lower speed and load cargo box, and when after reaching the set temperature range -18 ℃ ± 3 ℃, should maintain its stable inside temperature. However, when calculating the freezer is not cooling when inside temperature, can be used as a standard value the following empirical formula to calculate 1) cooled cargo (without ventilation) 0.0054 * (tw-tn) ℃ / h 2) frozen goods 0.0067 * (tw -tn) ℃ / h where tw and tn respectively, outside temperature and inside temperature ℃.
