The invention provides a hybrid refrigeration system, a control method thereof and a transportation refrigeration vehicle. The mixed refrigeration system comprises a first refrigeration device based on liquid nitrogen and used for adjusting the temperature of a container of the transportation refrigeration vehicle; the second mechanical-based refrigeration device is used for adjusting the container temperature of the transportation refrigeration vehicle; the controller is connected with the first refrigerating device and the second refrigerating device; the controller is configured to judge whether the difference between the container temperature and the set temperature is larger than or equal to a first threshold value or not when the refrigeration requirement of the container is received. If yes, the first refrigerating device is started independently or the first refrigerating device and the second refrigerating device are started at the same time; and if not, the second refrigerating device is independently started. According to the device and the method provided by the embodiment of the invention, the requirement on the capacity of the mechanical refrigeration device on the vehicle can be reduced, the weight and the size of the mechanical refrigeration device are reduced, and in addition, the time for reducing the temperature of the container to a set point at the time of starting up can be reduced.

    本发明提供了一种混合制冷系统、其控制方法和运输制冷车辆。混合制冷系统包括:调节所述运输制冷车辆的货箱温度的基于液氮的第一制冷装置;以及调节所述运输制冷车辆的货箱温度的基于机械的第二制冷装置;与所述第一制冷装置和所述第二制冷装置联接的控制器;其中,所述控制器配置成在接收到货箱的制冷需求时判断货箱温度与设定温度之差是否大于或等于第一阈值;如果是,则单独启动所述第一制冷装置或同时启动所述第一制冷装置和所述第二制冷装置;如果否,则单独启动所述第二制冷装置。根据本发明的实施例的装置和方法可降低对于车辆上的机械制冷装置的能力的要求,并且由此降低机械制冷装置的重量和体积,此外还能减少刚开机时降低货箱温度到其设定点的时间。
