Description

用于全电动冷藏运输车的冷藏机组
技术领域
本发明涉及电动冷藏运输车，尤其是涉及一种用于全电动冷藏运输车的冷藏机组。
背景技术
冷藏车广泛用于冷冻食品、奶制品、蔬菜水果、疫苗药品等冷冻或保鲜货物的公路运输。车型为封闭式厢式货车，具有独立的制冷机组。目前国家以及全球范围内都在降低能耗和大气污染而采用新能源汽车，特别是电动汽车。传统的冷藏机组制冷时是利用发动机来驱动冷藏机组压缩机工作而实现制冷，但电动汽车由于考虑车辆续航里程问题，因此车辆的电机功率都没有设计的很大，只考虑车辆载重。这样如果使用冷藏机组的同时再利用汽车电机来驱动行驶会影响车辆的动力提供，甚至会损坏汽车电机。另外如果在车辆停车充电时，机组继续使用车载电池的电源工作，这样会导致车载电池边充边放，长时间影响电池的性能及使用寿命。
发明内容
本发明目的在于提供一种保证电动冷藏运输车正常行驶的同时还能保证冷藏厢体正常工作的用于全电动冷藏运输车的冷藏机组。
为实现上述目的，本发明可采取下述技术方案：
本发明所述的用于全电动冷藏运输车的冷藏机组，包括车载直流高压电池组；所述车载直流高压电池组的电源输出端分别与DC转DC电源模块和变频器的电源输入端电连接；所述DC转DC电源模块和变频器的电源输入端分别与整流模块的电源输出端电连接，所述变频器的电源输出端与压缩机的电源输入端电连接；所述压缩机的介质出口连通设置有两路管道，其中第一管道通过依次连通设置的开关阀、设置在冷藏箱体外壁前部的冷凝器、储液器、干燥过滤器、视液镜和膨胀阀与设置在冷藏箱体内壁顶部的冷藏箱蒸发器的介质进口相连通；第二管道通过连通设置的化霜阀与所述冷藏箱蒸发器的介质进口相连通；冷藏箱蒸发器的介质出口通过第三管道与压缩机的介质进口相连通；所述DC转DC电源模块的电源输出端分别与所述冷凝器、冷藏箱蒸发器和化霜阀的电源输入端电连接。
本发明优点在于保证电动冷藏运输车可以正常行驶的同时还能保证冷藏厢体内货物的安全，且不影响电动汽车各个配件的使用。
附图说明
图1是本发明的管路及电气连接示意图。
具体实施方式
如图1所示，本发明所述的用于全电动冷藏运输车的冷藏机组，包括车载直流高压电池组1；所述车载直流高压电池组1的电源输出端分别与DC转DC电源模块2和变频器3的电源输入端电连接；所述DC转DC电源模块2和变频器3的电源输入端分别与整流模块4的电源输出端电连接，所述变频器3的电源输出端与压缩机5的电源输入端电连接；所述压缩机5的介质出口连通设置有两路管道，其中第一管道6通过依次连通设置的开关阀7、设置在冷藏箱体外壁前部的冷凝器8、储液器9、干燥过滤器10、视液镜11和膨胀阀12与设置在冷藏箱体内壁顶部的冷藏箱蒸发器13的介质进口相连通；第二管道14通过连通设置的化霜阀15与所述冷藏箱蒸发器13的介质进口相连通；冷藏箱蒸发器13的介质出口通过第三管道16与压缩机5的介质进口相连通；所述DC转DC电源模块2的电源输出端分别与所述冷凝器8、冷藏箱蒸发器13和化霜阀15的电源输入端电连接。
行车工作模式：
车载直流高压电池组1的电源输出端分别与DC转DC电源模块2和变频器3的电源输入端电连接，变频器3输出端输出的交流电源提供给压缩机5使用；另一部分DC转DC电源模块2输出DC24V或者DC12V电源直接供给冷凝器8的风扇17、冷藏箱蒸发器13的风扇18和化霜阀15用电。
停车工作模式：
外接AC电源与整流模块4的电源输入端连接，整流模块4输出端一部分与变频器3输入端连接后，变频器3输出端输出的交流电源提供给压缩机5使用；另一部分电源提供给DC转DC电源模块2后，DC转DC电源模块2输出DC24V或者DC12V电源直接供给冷凝器8的风扇17、冷藏箱蒸发器13的风扇18和化霜阀15用电。
制冷模式：
制冷压缩机5介质出口出来的高压气体，第一管道6经开关阀7（此时化霜阀15处于关闭状态）通过冷凝器8散热后，气液混合制冷剂经储液器9出口经干燥过滤器10与视液镜11进口连通，所述视液镜11出口通过膨胀阀12与冷藏箱蒸发器13的介质进口连通，冷藏厢蒸发器13介质出口通过第三管道16与压缩机5的介质进口相连通。
热气融霜模式：
为了保证制冷效果在设备长时间制冷后冷藏厢蒸发器13会结霜严重，进而导致制冷效果变差，这时需要除霜：压缩机5介质出口出来的高压气体，第二管道14经化霜阀15与冷藏箱蒸发器13的介质进口相连通（此时开关阀7处于关闭状态），冷藏厢蒸发器13的介质出口通过第三管道16与压缩机5的介质进口相连通。
