中文摘要：

为掌握不同加湿方式对气调保鲜环境调控的影响，搭建了气调保鲜环境综合调控试验平台，对比超声波和高压雾化2种加湿方式对气调保鲜环境调控的影响。结果表明：超声波加湿对厢体内气体成分变化无影响，高压雾化加湿可引起厢体内O2和CO2体积分数的明显波动；超声波加湿在耗电量和液氮消耗量上比高压雾化加湿分别节能34．9％和57．7％。

英文摘要：

An experimental platform for integrated control of fresh-keeping environment with controlled atmosphere （CA） system was established to research the effects of different humidifying methods on the regulation of CA environment. A comparison was made between the effects of two different humidifying methods, ultrasonic humidification and high pressure atomized humidification, on the regulation of CA environment. The results indicated that ultrasonic humidification exerted no influence on gas composition in the experimental container and high pressure atomized humidification caused distinct fluctuation on the volume fractions of O2 and CO2contrarily. Furthermore, ultrasonic humidification consumed 34.9 percent less of electric energy and 57.7 percent less of liquid nitrogen than high pressure atomized humidification.
