摘要

配送过程中冷藏车开门时的热质交换会引起车内空气温湿度的剧烈变化，这使得食品的品质难以得到保证。针对目前冷藏车开门卸货时存在的一些问题，进行了对比实验，对不同条件下的车内温度、相对湿度变化进行了分析，得出在开门时长一定的情况下车厢内外空气温差是影响车内温升的主要因素，采用PVC门帘可以有效地抑制车内温度升高，一定程度上保证食品安全。

Abstract

The dramatic changes of interior air temperature and humidity induced by heat and mass transfer can make the quality of food no longer be assured while the door of the refrigerated truck is opened in the distribution. Comparative experiments are conducted according to the problems in the unloading process. The variations of temperature and humidity under different conditions are analyzed. The conclusion shows that the temperature difference between the inside and outside air is the main factor which impact the temperature rise of interior air

and the use of PVC curtain can effectively inhibit the elevated temperature inside the vehicle and ensure food safety to some extent.
