According to the present invention, a waste heat utilization system of a refrigeration truck comprises: a refrigerator box; a refrigerator unit for maintaining the internal temperature of the refrigerator box so that the contents contained in the refrigerator box do not decay; a fuel cell for providing electrical energy necessary for the refrigerator unit; an outdoor unit connected to the refrigerator unit to perform heat exchange outside so that the refrigerator unit can maintain low temperatures; a waste heat collection unit for collecting waste heat generated in the fuel cell as the electric energy is provided, and providing the waste heat to the outdoor unit that is expected to freeze in the winter season; and a control unit for providing the heat generated in the fuel cell to the refrigerator box, the outdoor unit, and a condenser when the heat is required by monitoring the temperature status of the refrigerator box, the outdoor unit, and the condenser in real time and controlling a valve formed at a front end of the waste heat collection unit. Therefore, the waste heat utilization system can increase energy efficiency by recycling waste heat generated in the fuel cell.
