The temperature at which a refrigerated truck cools down is determined by the items stored in the vehicle. The specific introduction from the refrigerated truck manufacturer is as follows:

Before loading goods onto a refrigerated truck in Chongqing, the interior of the truck is cleaned and disinfected. The temperature at which the refrigerated truck is cooled is determined by the items stored on board. The specific introduction is as follows:

1. Before loading goods onto Chongqing refrigerated trucks, clean, disinfect, and ventilate the interior of the refrigerated trucks. Meat products that come into direct or indirect contact with truck surfaces and become contaminated without being cleaned and disinfected; Some foods are prone to absorbing odors and require ventilation to avoid strong odors in the truck as much as possible.

2. Before loading the cargo, it is necessary to pre cool the cargo and cargo hold. The design purpose of refrigerated trucks is to transport goods while maintaining the loading temperature. Loading goods at high temperatures or high refrigeration temperatures may result in deterioration of the quality of the goods.

3. Circulation of cargo hold air conditioning. The cargo hold should be kept at the same temperature, and attention should be paid to providing space for the placement of goods and not stacking them too full.

4. Quickly import and export goods. When the refrigerated truck door is opened, the airflow from the outside will cause the air inside the car to be lost and the temperature to rise. The opening time should be shortened as much as possible.

5. Check if the coolant level gauge of the refrigerated truck has the correct coolant volume, and the pointer should be within the white range. If the coolant level is within the red range, add coolant to the coolant tank. Under normal circumstances, the coolant is a mixture of ethylene glycol and water, and should be protected against freezing at -34 ℃.

6. The battery terminals of the refrigerator should be firm and corrosion-resistant. The electrolyte should be at the full mark.

7. The belt should be in good condition and adjusted to the appropriate level of expansion. The sag distance between the pulleys is 13mm from the center.

8. Inspect all electrical connectors in the electrical control circuit to ensure they are securely fixed. Wires and terminals should be free from corrosion, burning, cracking, or moisture.
