如图4所示，所述制冷机组8采用压缩蒸汽制冷，包括压缩机14、冷凝器15、节流阀16和蒸发器13，其制冷剂采用R134a，该制冷剂具有稳定、无毒、环保等优点，不破坏臭氧层。蒸发器13的冷气出气口为制冷机组的冷气出口，在蒸发器13内制冷剂吸热，使空气降温，实现了制冷机组的降温作用，制冷剂吸热后由液态变为气态。蒸发器13的制冷剂出口与压缩机14的进口连接，在压缩机内气态的制冷剂被压缩，从而使制冷剂被压缩为液态，压缩机14的出口与冷凝器15的入口连接，冷凝器15通过节流阀16与蒸发器13的入口连接，降温后的制冷剂最终流入蒸发器13内，进行下一轮的制冷循环。As shown in Figure 4, the refrigerating unit 8 adopts compressed steam refrigeration, including a compressor 14, a condenser 15, a throttle valve 16 and an evaporator 13, and its refrigerant adopts R134a, which is stable, non-toxic and environmentally friendly.

本实用新型的工作过程如下所述：当冷藏集装箱的负荷相对较低时，所需要的冷量也少。电磁阀Ⅰ10开启，电磁阀Ⅱ12关闭，制冷机组8工作，经过制冷机组8后的回风变为冷空气，在电动调流阀11的调节作用下，一部分冷空气直接通过送风口5进入冷藏集装箱的箱体1内，另一部分通过蓄冰器4后再送入箱体1内，并且两部分冷空气的比例是可以根据冷藏集装箱所需的冷量进行调节的。随着冷空气进入蓄冰器4，盘管外部的水凝结为冰，当蓄冰器4内的水完全凝固为冰的时候，制冷机组8就可以关闭，此刻电磁阀Ⅰ10关闭，电磁阀Ⅱ12打开。回风经过蓄冰器的换热盘管403时，由于换热盘管403外的温度低，会进行热交换，使流过换热盘管403的空气温度降低，同时盘管外的冰吸收热量后融化为水，低温空气经送风口5送至冷藏集装箱的箱体1内。仅仅通过蓄冰器4中所储存的冷量，即可维持冷藏集装箱内冷空气的供给，当蓄冰器内的冰完全融化后，提供的冷量不能维持冷藏集装箱的所需冷量时，制冷机组8重新开始工作，周而复始。此时通过蓄冰器的使用，实现了制冷机组的间歇工作，降低了制冷机组的运行时间，进而实现节能。当冷藏集装箱内放置高温货物时，温度传感器会检测到回风温度的迅速上升，此刻电磁阀Ⅰ10与电磁阀Ⅱ12同时打开，回风同时通过制冷机组8及蓄冰器4后送入箱体1内，这样可以增大单位时间内送入冷藏集装箱的冷量，最快地降低货物温度，进而提高货物的冷藏品质。综上所述，通过制冷机组与蓄冰器的配合工作，可以使冷藏集装箱的制冷机组呈现间歇式工作状态，降低了制冷机组的运行时间，实现了冷藏集装箱的节能；与此同时，也增强了冷藏集装箱的制冷性能，提高货物的冷藏品质。The working process of the utility model is as follows: when the load of the refrigerated container is relatively low, the required cooling capacity is also small. The solenoid valve I10 is opened, the solenoid valve II12 is closed, the refrigeration unit 8 is working, and the return air after passing through the refrigeration unit 8 becomes cold air. Under the regulation of the electric flow control valve 11, a part of the cold air directly enters the refrigerated container through the air outlet 5 Inside the tank 1, the other part is sent into the tank 1 after passing through the ice accumulator 4, and the ratio of the two parts of cold air can be adjusted according to the cooling capacity required by the refrigerated container. As the cold air enters the ice accumulator 4, the water outside the coil condenses into ice. When the water in the ice accumulator 4 is completely condensed into ice, the refrigeration unit 8 can be closed. At this moment, the solenoid valve I10 is closed, and the solenoid valve II12 Open. When the return air passes through the heat exchange coil 403 of the ice accumulator, due to the low temperature outside the heat exchange coil 403, heat exchange will be carried out, so that the temperature of the air flowing through the heat exchange coil 403 will decrease, and at the same time, the ice outside the coil will absorb Melt into water after the heat, and the low-temperature air is delivered to the casing 1 of the refrigerated container through the air outlet 5 . The supply of cold air in the refrigerated container can be maintained only by the cold capacity stored in the ice accumulator 4. When the ice in the ice accumulator is completely melted, the provided cold capacity cannot maintain the required cold capacity of the refrigerated container. The refrigerating unit 8 starts working again and goes round and round. At this time, through the use of the ice accumulator, the intermittent operation of the refrigerating unit is realized, the running time of the refrigerating unit is reduced, and energy saving is realized. When high-temperature goods are placed in the refrigerated container, the temperature sensor will detect a rapid rise in the temperature of the return air. At this moment, the solenoid valve I10 and the solenoid valve II12 are opened at the same time, and the return air passes through the refrigeration unit 8 and the ice storage 4 at the same time and then is sent into the box body 1. In this way, the cooling capacity sent into the refrigerated container per unit time can be increased, the temperature of the goods can be lowered as quickly as possible, and the refrigerated quality of the goods can be improved. To sum up, through the cooperative work of the refrigeration unit and the ice storage, the refrigeration unit of the refrigerated container can be in an intermittent working state, which reduces the running time of the refrigeration unit and realizes the energy saving of the refrigerated container; at the same time, it also enhances the Improve the refrigeration performance of the refrigerated container and improve the refrigerated quality of the goods.
