The present invention provides a hybrid refrigeration system, a control method thereof, and a transportation refrigeration vehicle. The hybrid refrigeration system comprises: a liquid nitrogen based first refrigeration device (5) for regulating the temperature of a cargo box (3) of a transportation refrigeration vehicle; a mechanical based second refrigeration device (4) for regulating the temperature of the cargo box of the transportation refrigeration vehicle; and a controller connected to the first refrigeration device and the second refrigeration device; wherein, the controller is configured to determine whether the difference between the temperature of the cargo box and the set temperature is greater than or equal to a first threshold when receiving a refrigeration demand for the cargo box; if so, start the first refrigeration device alone or start both the first refrigeration device and the second refrigeration device simultaneously; and if not, start the second refrigeration device alone. The device and method according to the embodiments of the present invention can reduce the requirement for the capacity of the mechanical refrigeration device on the vehicle, thereby reducing the weight and volume of the mechanical refrigeration device, and further reducing the time to lower the temperature of the cargo box to its set point when it is first started.
