Speaking of truck refrigeration units, in fact, I often say that under the premise of smooth operation of the refrigeration unit, it can provide stable cooling conditions, so how to maintain continuous temperature is also very important. In the previous section, I talked about the material of the truck's cooling unit's insulation car. Most of the choices are inside and outside the FRP panel, because the FRP panel has unique advantages.
In general, the daily maintenance and maintenance of the truck's cooling unit's insulation compartment is mainly reflected in the inspection of the exterior surface of the compartment, the inspection of the interior surface of the compartment, the inspection of the corners of the interior and exterior of the compartment, the inspection of the interior of the compartment, and the internal lighting and cooling. Air outlets, etc. For the outer surface of the truck refrigeration unit, I often remind the users who come to our factory to pick up the car, do not scrape the car body, which on the one hand reduces the ability of FRP to withstand pressure, and is more prone to aging deformation, on the other hand The internal filled polyurethane leaks and affects the insulation performance of the car.
For the maintenance of the inner surface of the truck refrigeration unit, it is necessary to adjust the temperature control. Do not freeze the surface of the car body. If the air humidity is relatively large, it is necessary to pack the refrigerated products as much as possible, especially the aquatic products. Evaporation into the interior of the car reduces the likelihood of icing inside the truck's refrigeration unit. If there is a layer of ice on the inner surface of the truck refrigeration unit, it should be removed with a de-icing shovel in time after each shipment, to prevent the ice layer from getting thicker and thicker, not only affecting the storage space of the car, but also increasing the vehicle. Its own weight increases fuel consumption. Also internal attention should be paid to avoid damage to the inner surface of sharp goods or boxes.
Finally, it is the maintenance of internal electrical equipment that I also often mention, because the electrical equipment of the truck refrigeration unit is in a relatively high humidity environment with low temperature. To prevent the occurrence of various short circuits caused by exposed power lines, it is also necessary to prevent unnecessary damage caused by alternating heat and cold to the lighting equipment that generates heat.
