A truck equipped with an insulated compartment and a truck refrigeration unit is called a refrigerated truck. You may also encounter the following situations when using a refrigerated truck, here are some solution for you.
1. When the refrigerated truck is idling for a long time in poor traffic or traffic jam, its engine water temperature gauge shows too high, its fan works too long in high gear, the engine noise increases, and the fault is most obvious when the air conditioner is turned on when the temperature is too high.
Solution: After the car is hot, check the water return of the return pipe at the upper end of the antifreeze storage tank. If the return water is not smooth or blocked, the water temperature will be too high.
2. If the refrigerated truck turns on the air conditioner when the temperature is too high, unsteady idle speed, excessive speed fluctuation,the acceleration is weak, and the engine makes abnormal noise.
Solution: Check whether there is too much dust between the condenser of truck refrigeration unit and the water tank, and clean it thoroughly with high-pressure air to ensure that the water tank and condenser have good heat dissipation performance. Reminder: usually pay attention to wipe the dust between the condenser and the water tank.
3.When the truckis cold, the air-conditioning’stemperature is very cold, and the cooling effect of the air-conditioning is not obvious when the truckis hot; and there is a large resonance hum in the air conditioning system.
Solution: Due to the irregular addition and replacement of antifreeze, the engine water channel and water tank will be blocked in advance and the water temperature will be high. The antifreeze is replaced once every two years, and original parts must be used when replacing and adding. Reminder: After adding water to the engine cooling system, or the concentration of the added antifreeze exceeds 60%, the water temperature will be too high.
