本文提出一种快速测定冷藏运输工具传热系数的新方法.并根据部分国内外资料进行了核对,其结果表明,新方法比目前常用的方法方便、准确.文中还提出了另一种新的快速测试法——热容量法.这种方法兼有热法测试和冷法测试的优点,既可在不必测量制冷量的前提下,直接测定工作条件(低温)下的传热系数,又能测定使用过的含水隔热结构的实际传热系数.为了克服常用检验方法的缺点,还提出了以Q/K为指标的新检验方法.它可方便地在现场使用,而且费时较少.
In this paper, a new method for rapid determination of heat transfer coefficient of refrigerated transport is proposed and checked according to some domestic and foreign data. The results show that the new method is more convenient and accurate than the commonly used methods. Another new Rapid test method - the heat capacity method. This method combines the advantages of both thermal test and cold test, not only without measuring the cooling capacity of the premise, the direct determination of the working conditions (low temperature) of the heat transfer coefficient, but also measured The actual heat transfer coefficient of the used water-insulated structure In order to overcome the shortcomings of the commonly used test methods, a new test method based on Q / K is also proposed, which can be conveniently used in the field and takes less time.
