At present, the refrigerated trucks on the market are mainly one compartment and one temperature zone. This will lead to a situation in which it is difficult to collect goods in the same temperature range in actual transportation. It takes a long time to wait for the supply of goods. . If in order to ensure the quality of cold chain service, the unloading rate is often too high, resulting in high transportation costs. Therefore, diesel multi temperature cooling unit can better meet the business needs of cold chain logistics.
To realize the effect of refrigerated trucks with multiple temperature zones, the refrigerated trucks need to be divided into compartments. The refrigerated car body can be divided into an integral car body and a sub-storage car body. The compartment body is divided into multiple compartments to realize the transportation of goods with different temperature requirements; the overall compartment is without compartments, and the temperature in the entire compartment is the same.
The compartment is divided into a plurality of different temperature zones by the temperature zone compartment, a plurality of air supply openings are opened on the air supply layer, and a plurality of air return openings are opened on the return air layer. Set the return air layer between the supply air layer and the temperature zone, and set the air duct barrier separating the two between the supply air layer and the return air layer. The problem of narrow and fixed air supply position due to the internal machine of the refrigeration unit is solved. It makes the air supply more uniform, and the temperature control efficiency of different temperature zones is higher.
A temperature sensor is installed at the air outlet, and the temperature sensor feeds back the temperature detected at the air outlet to the controller, so that the controller adjusts the stepping motor and the drive screw according to the temperature information fed back by the temperature sensor, and then The size of the air supply port is adjusted to adjust the air supply volume and adjust the temperature detected by the temperature detector in a timely manner.
Diesel engine refrigeration unit D1000MT was installed on truck in Latin America. One condenser with two evaporators,Refrigeration for box 35 to 55 m3 length, half for frozen -20C, the other half for chiller -5C.
