As summer approaches, the weather is getting hotter. The refrigerated trucks are welcoming the sales season. When it comes to refrigerated trucks, they have to say how to maintain them. The following is a small series of maintenance methods for refrigerated trucks for your reference.

1.    Pre-cooling the cargo and the van box before transportation. The refrigeration unit will keep the temperature of the cargo after loading, and if the cargo with higher temperature or the temperature inside the cabin is directly placed in the compartment, it will increase the difficulty of lowering the temperature inside the compartment to the predetermined temperature. Therefore, it is necessary to pre-cool the goods and the car before loading the goods.

2.    Pay attention to keep the air circulation in the cabin smooth when loading. In order to maintain the temperature balance in the compartment, it is necessary to pay sufficient attention to the position of the cargo, so that the cargo cannot be loaded to the top of the compartment, and the cargo is not blocked by the outlet and entrance of the air conditioner. Otherwise, the cargo located in the middle of the compartment will be easy to flow due to the air. Deterioration, decay.

3.    Loading and unloading goods should be quick. After the door of the refrigerated truck compartment is opened, the external airflow will flow into the compartment, which will cause the temperature inside the compartment to rise, affect the quality of the cargo, increase the operating load of the refrigeration unit, and increase the fuel consumption; therefore, the loading and unloading of the cargo should be rapid, and Stop the refrigeration unit.

4.    The battery terminal of the refrigerated truck must be secure and free of corrosion. The electrolyte should be at the full mark.

5.    The belt must be good and adjusted to the proper degree of expansion. The sag is 13 mm in the center of the span between the pulleys.

6.    Electrically inspect all electrical connections in the electrical control circuit to ensure they are securely fastened. Wires and terminals should be free of corrosion, burning and cracking.

7.    Structural inspection of the unit for leaks, loose or broken parts and other damage.

8.    The gasket of the gasket unit should be tightly pressed and in good condition.

9.    The refrigerated truck coil condenser and evaporator coil should be clean and free of dirt.

10.   When the cargo compartment is loaded, the cargo cannot block the evaporator air outlet and the return air outlet, and keep the air circulation in the cargo compartment unblocked to ensure that there will be no hot spots in the compartment.
