Abstract: It is important to keep the healthy quality of ocean seamen in our country. And the controlled atmosphere container for shipment is one of key equipments used for this purpose. In this paper, a general design method for the container is built. The characteristic of the method is working conditions segmentation of nitrogen making, refrigeration and humidification functional unit. The problem of parameters matching which lead by the container small volume is solved by this method. This research is significance for correlation studies. The calculation example at last shows that the design of controlled atmosphere container can be finished very well used this method.
Key words: controlled atmosphere container     nitrogen making functional unit     refrigeration functional unit     humidification functional unit

1）制氮和制氧系统同时运行，将温度和氧气浓度降到目标值；

2）加湿系统运行，使湿度达到目标值；

3）臭氧杀菌系统运行；

4）乙烯脱除系统运行。

1.2 气调保鲜集装箱基本参数

2 气调保鲜集装箱设计计算 2.1 制氮功能模块计算

 $Q = \frac{v}{\tau }\ln \frac{{{{C}}{{{O}}_2}^2 - {{C}}{{{O}}_2}^0}}{{{{C}}{{{O}}_2}^0 - {{C}}{{{O}}_2}^2}}{\text{。}}$ (1)

2.2 制冷功能模块计算

 $G = \frac{{\Sigma V \cdot \rho \cdot \gamma }}{{1 000}}{\text{，}}$ (2)

 $d = \lambda \left[ {{R_0} - \left( {\frac{1}{{{\alpha _w}}} + \sum\nolimits_{i = 1}^m {\frac{{{\delta _i}}}{{{\lambda _i}}}} + \frac{1}{{{\alpha _n}}}} \right)} \right]{\text{，}}$ (3)

 $K = \frac{1}{{\Sigma R}} = \frac{1}{{\frac{1}{{{\alpha _w}}} + \sum\nolimits_{i = 1}^m {\frac{{{\delta _i}}}{{{\lambda _i}}}} + \frac{1}{{{\alpha _n}}}}}{\text{，}}$ (4)

 ${Q_1} = K \cdot A \cdot a \cdot \left( {{t_w} - {t_n}} \right){\text{，}}$ (5)

 ${Q_2} = \frac{{m\left( {{h_1} - {h_2}} \right)}}{{3.6t}}{\text{，}}$ (6)

 ${Q_3} = \frac{{\left( {{h_w} - {h_n}} \right)V{r_n}}}{{3.6}}{\text{，}}$ (7)

 ${Q_4} = \frac{{m\left( {{\phi ^1} - {\phi ^2}} \right)}}{2}{\text{。}}$ (8)

 ${W_2} = \frac{{\left( {{Q_1} + {Q_4} + {Q_5}} \right) \cdot {n_{t1}}}}{{{n_{t2}}}}{\text{，}}$ (9)

2.3 加湿功能模块计算

1）制冷功能模块工作过程；2）换气功能模块工作过程；3）气调功能模块工作过程。

 ${W_{\rm{\text{冷}}}} = G\left( {{d_r} - {d_s}} \right)/1 000{\text{，}}$ (10)

 ${W_{\rm{\text{气}}}} = G{d_n}/1 000{\text{，}}$ (11)

2.4 乙烯脱除功能模块

2.5 CO2 脱除功能模块计算

CO2 脱除系统的能力应根据贮藏果蔬的呼吸强度、气调库内贮藏空间体积和贮藏量来确定，一般依据下式计算。

 $M = \left[ {\frac{V}{\tau }\left( {{C_{{\rm{C}}{{\rm{O}}_{\rm{2}}}}}^1 - {C_{{\rm{C}}{{\rm{O}}_{\rm{2}}}}}^2} \right) + G \cdot C} \right] \cdot {n_{t3}}/{n_{t4}}{\text{，}}$ (12)
