What causes the temperature inside the refrigerated truck compartment hard to come down, in fact, for this problem we are often heard. But many refrigerated truck users do not know the reasons, but do not know how to solve this problem. Chang Jie special vehicle from three aspects summarized reasons:
First of all, we should note that when the goods stacked in front of the evaporator outlet do not stack too much cargo, otherwise it will hinder the flow of air, the obstruction of the goods will lead to cold air short circuit. A minimum distance of 220 mm must be maintained between the top of the cargo and the roof. Be sure to ensure that the height of the cargo load is not higher than the balance of the outlet height. If the front of the outlet blocked by the goods or too close to the goods, not only will affect the storage and transportation of goods temperature, but also affect the normal work of the cooling unit.
Second, the refrigerated truck cooling unit as a result of some of the defrost design is the use of air induction to defrost. When the cargo is too close to the outlet when the refrigeration unit in the evaporator coil evaporator will quickly frost or ice, this time the air sensor system will operate, the refrigerator car unit will quickly enter the defrost state. When the coil temperature rises to 9 degrees (design temperature), the defrosting is immediately terminated. So refrigerators inside the refrigeration unit will appear the cycle of the above-mentioned operation, resulting in the body temperature drop is not down to the phenomenon, to everyone's intuitive feeling is the refrigerator car refrigeration unit frequently in defrosting work, but the temperature inside the box did not Significant cooling. Basically because the refrigerated cargo compartment load is too high, too many reasons for the frequent work of the cooling unit can drop the temperature is not down.
Third: Sometimes the refrigerated truck cooling unit has been in the work of the state, but the temperature inside the compartment is not able to reach the preset temperature cooling effect, in the face of this problem, the owners of refrigerated trucks is also very troublesome, fear Transportation of goods due to reach the temperature of the reasons for deterioration, affecting their turnover.
