摘　　要：首先对以液体CO2为冷源的这种新型水产品冷藏运输车的保温性能进行了实验,可以看出相同液体CO2及环境温度下,厢温维持在0℃的时间比维持在-18℃时延长了80%,每打开一次厢门,要用约20min的时间使厢温降到设定温度;接着对三种水产品冷藏运输车的运行经济性进行了比较,结果是液体CO2冷藏车的运输费用是机械冷藏车的70.4%,是冷板冷藏车运输费用的88.1%。因此,这种新型水产品冷藏运输车具有很好的开发价值与市场前景。This article firstly processed experimental study on heat preservation of liquid carbon dioxide refrigerated lorry, the results showed that, the time of compartment temperature at 0℃ was 80 percent longer than that of it at -18℃, when mass of liquid CO2 and circumstance temperature were the same; also showed that it took about 20 minutes that compartment temperature lowered to enactment temperature when it opened the door of compartment once. Then this article processed economic analysis on run economy of liquid carbon dioxide refrigerated lorry, summarized up that the run fee of liquid carbon dioxide refrigerated lorry is 70.4 percent that of mechanical refrigerated lorry; and the run fee of it is 88.1 percent that of cooling board.
