The invention relates to the technical field of refrigeration, and discloses an environment-friendly intelligent cold chain logistics vehicle refrigeration generator unit control system. The system comprises a temperature control system and an engine dual fan system which are controlled by a controller. The controller is electrically connected with an ECU, and the system further comprises a speedadjusting system controlled by the ECU. A freezing box provides temperature information for the temperature control system. A temperature sensor on an engine sends temperature information to the controller, the controller judges the temperature of the engine according to the temperature information of the engine, and a temperature adjusting instruction is sent to the engine dual fan system. The speed adjusting system acquires the actual rotating speed of a generator set through a rotating speed sensor, the controller achieves judgment and adjusts the rotating speed to be within the set range according to the difference of the actual rotating speed and the set target rotating speed and according to the difference size, a speed adjusting instruction is sent to the ECU, and the ECU controls the speed adjusting system to adjust the speed according to the instruction. Through the adoption of the self-control temperature decrease mode, the low-speed running noise reduction manner and the freezing box self-adaptive temperature control technology, the aims of saving energy and protecting the environment are achieved.
