中文摘要：

为掌握液氮充注气调运输保鲜环境因素间的耦合关系,搭建了气调运输保鲜环境调控试验平台。通过试验分别研究了制冷、高压雾化加湿、液氮充注气调、换气等调节过程对保鲜环境中温度、相对湿度、氧气体积分数、二氧化碳体积分数等参数的影响。结果表明：液氮充注气调在快速降低氧气体积分数的同时,对温度和相对湿度影响均较大;制冷在降低温度的同时,对相对湿度影响较大;采用高压雾化加湿时,对温度影响较小,空气压缩机吸入外界空气将对氧气体积分数产生较大影响,而吸入厢体内气体对氧气体积分数影响均很小;换气对厢体内氧气体积分数和二氧化碳体积分数影响较大。研究结果可供气调运输保鲜环境综合调控提供参考。

英文摘要：

In order to research the environmental factors coupling effect in fresh-keeping transportation with controlled atmosphere,an experimental platform for environmental control was established.Experiments were carried out to investigate the effects of regulation process such as refrigeration,high-pressure atomizing humidification,liquid nitrogen injection and ventilation on temperature,humidity,O 2 concentration,and CO 2 concentration of the fresh-keeping environment.Results indicated that liquid nitrogen injection during controlled atmosphere process could rapidly reduce the O 2 concentration,meanwhile significantly affecting temperature and humidity in the container.Similarly,refrigeration had a great impact on the humidity when decreasing the temperature.High-pressure atomizing humidification made little effect on temperature when increasing the humidity,whereas the compressor intaking the air outside the container would exerted dramatic effect on the volume fraction of O 2 than intaking the air inside.Ventilation had great influence on the volume fraction of O 2 and CO 2.The results can provide references for integrated control strategy of fresh-keeping transportation with controlled atmosphere.
