传统的果蔬贮藏保鲜方法有简易贮藏、通风库贮藏、辐射保鲜、化学保鲜、冷库贮藏。简易贮藏、通风库贮藏设备简单、投资少，但贮藏效果差，贮藏期短，腐烂损失严重。辐射及化学保鲜在部分水果上有一定适用性，但存在辐射及化学残留污染，不是所有果蔬都能应用。
The traditional fruit and vegetable fresh-keeping method is simple and easy storage, ventilation storage, radiation, chemical preservation, cold storage storage. Simple and easy storage, ventilation storage equipment is simple, less investment, but poor storage effect, short storage period, decay severe losses. Radiation and chemical preservation has certain applicability on the part of the fruit, but no radiation pollution and chemical residues, not all fruit and vegetables can be used.
Weakness: suitable for large enterprises and controlling. Input is high. Cost is high. The high cost of maintenance. Not applicable.
（1）低压（0.8bar)运行，比同性能的PSA及膜制氮机节能80%左右。
(1) low voltage (0.8 bar), than with the performance of PSA and membrane nitrogen making machine and energy saving by about 80%.
（2）降氧效果提高30%以上，可将气调库内氧气含量控制在1%以下，甚至可以达到0.3%
(2) the effects of oxygen reduction increased by more than 30%, in the controlling oxygen content is controlled under 1%, can even reach 0.3%
（3）维护成本低。稳定可靠。设备中的主要活性炭吸附模块寿命长达15年以上。（中空纤维膜制氮机中膜组昂贵，寿命只能持续2~3年）
(3) the maintenance cost is low. Stable and reliable. Equipment, the main active carbon adsorption module life for more than 15 years. (hollow fiber membrane membrane group in nitrogen making machine is expensive, life lasts for 2 ~ 3 years)
（4）与库体止漏系统配合更有效防止气调库气体泄漏。
(4) cooperate with library body seepage system more effective preventing and controlling gas leak.
（5） 气调库气体内循环。更有效的节约运行成本。
(5) inner loop controlling gas. More effective to save running cost.
