Sometimes refrigerating truck refrigeration unit has been in the working state, but the temperature in the compartment is not able to reach the preset temperature cooling effect. When encountering this kind of problem, the refrigerated vehicle owner is also very upset, afraid of the transported goods. Deterioration due to the lack of temperature, affecting their own turnover. In fact, we often hear about this issue. We should be careful not to stack too much cargo in front of the evaporator outlet when stacking the goods. This will hinder the circulation of cold air. Blockage above the cargo will cause a short circuit in the cold air flow. A minimum distance of 220 mm must be maintained between the top of the cargo and the roof. It must be ensured that the height of the loaded cargo is not higher than the equilibrium height of the air outlet. If the front of the air outlet is blocked by the goods or is too close to the goods, it will not only affect the storage and transportation temperature of the goods, but also affect the normal operation of the refrigeration unit. On the other hand, some defrosting designs for refrigerated truck refrigeration units use air induction for defrosting. When the goods are too close to the air outlet, the coils in the evaporator of the refrigeration unit in the refrigerated truck will quickly frost or freeze. At this moment, the air induction system will immediately operate, and the refrigeration unit will quickly enter the defrosting state. When the coil temperature rises back to 9 degrees (design temperature), the defrost ends immediately. As a result, the refrigeration unit in the refrigerated vehicle will undergo the above-mentioned cyclic operation, resulting in the phenomenon that the temperature in the chamber will not fall down, giving us the intuitive feeling that the refrigerating unit of the refrigerated truck frequently defrosts, and the temperature inside the refrigerator does not Obvious cooling. Basically, because the load of the refrigerated carriage is too high or too high, the frequent operation of the refrigeration unit can reduce the temperature of the carriage.
