Some of the defrosting designs of semi truck freezer use air induction defrosting. When the goods are too close to the air outlet, the coil in the evaporator of refrigeration unitswill quickly frost (or ice.The air induction switch will act immediately, and the unit will quickly enter the defrost Frost state; when the coil temperature rises to about 9 degrees (design temperature), the defrosting ends immediately.
The semi truck freezerrepeat the above-mentioned operations, which will lead to the phenomenon that the temperature inside the compartment cannot drop.The intuitive feeling for everyone is that semi truck refrigeratoralways defrosts frequently. In fact, it was caused by the high (too much) cargo.
Therefore, in the process of using semi truck refrigerator, we must pay attention to loading to avoid unnecessary losses caused by deterioration of goods. Leave a gap of 10 cm around the cargo to ensure unobstructed airand avoid temperature differences inside the cargo box. In addition, do not stack goods on the air inlet and outlet and the roof.
