1. The good or bad of the compartments of a refrigerated truck is mainly due to the good or bad thermal insulation performance of the thermal insulation box. Then there is a great relationship between the thermal insulation performance and the structure of the vehicle. Therefore, as long as there is any mistake in the middle, it will affect the play of the box. Therefore, when we purchase refrigerated trucks, we first need to look at the thermal conductivity of the insulation material and the filling is not compact. The second is to observe the sealing effect of the insulation layer in the box plate of the heat-insulating box. Then you need to look at whether there is a metal thermal bridge, and whether the connection between the plate and the plate in the observation box is not cracked and compact. The last is the observation of the sealing performance of the mouth and the door. If the vehicle's thermal insulation and thermal insulation performance is better, then it will prove that the time of its insulation will be longer. When it reaches the same temperature inside the vehicle, the working time of the refrigerant in the refrigerated truck will also be shortened, Will produce more fuel consumption.
2. If the compartments of refrigerated trucks are relatively heavy, then the fuel consumption will be more and more during the entire process of transportation. Conversely, if the refrigerator compartment is light, fuel consumption will be reduced. Cold chain refrigerated and heat-insulated compartments are used in foamed polyurethane, while the exterior and interior of the compartments represent the glass plates used. The edge of the box is also a lightweight aluminum material. Not only will the vehicle be much lighter, but the strength of the cabin structure will also be much higher.
3, high-quality refrigerated truck insulation compartment, appearance and inner skin of food grade glass steel plate used to produce. Some vehicle manufacturers produce refrigerated carts with painted steel plates for their inner and outer skins. After the relevant experiment surface, the corrosion resistance of FRP plates is 3-5 times higher than those of ordinary metal materials, and it will be easier to repair. Therefore, the use of refrigerated trucks will have a longer lifespan, and those with better quality insulation will last around 15-20 years. If the design of the refrigerator body of the refrigerator car is unreasonable, then for a long period of time, the adhesive glue will be aged. The outer skin and inner skin will have delamination conditions, and the heat insulation performance will be Can not reach the transport standards, and will also be more likely to breed bacteria, not only reduces the quality of food transport, but also makes the box foam insulation when absorbing water, reducing the insulation of the compartment.
