六十年代初期,深冷技术首次应用于冷藏运输。应用表明,液氮制冷系统是唯一的、在商业上可与机械制冷系统相竞争的冷藏技术。在欧洲使用液氮制冷运送的货物已超过十万件。美国液氮制冷的车辆数以万计。液氮制冷系统的优点:可运送各种易腐货物,如新鲜水果蔬菜、肉类油脂、冻结货物及各种饮料;液氮制冷系统集中了冷藏运输和气调运输的优点,给车内创造了比较理想的环境,使易腐货物保持不变质,因为氮气对易腐货物的新陈代谢有抑制作用。国际铁路联盟科研所试验证明,
In the early 1960s, cryogenic technology was first applied to refrigerated transport. Applications show that liquid nitrogen refrigeration systems are the only refrigeration technology commercially available that competes with mechanical refrigeration systems. In Europe, more than 100,000 are shipped using liquid nitrogen refrigeration. There are tens of thousands of vehicles for liquid nitrogen in the United States. Liquid nitrogen refrigeration system advantages: can transport a variety of perishable goods, such as fresh fruits and vegetables, meat fat, frozen goods and a variety of beverages; liquid nitrogen refrigeration system focused on the advantages of refrigerated transport and air transport, to the car to create An ideal environment keeps perishable goods intact, as nitrogen can have an inhibitory effect on the metabolism of perishable goods. International Union of Railways research institutes have proved that,
