1. Refrigerated trucks The refrigerated compartments must be pre-cooled before loading. Refrigerated compartment prices

  Because the vehicle is parked in the open air, the cabin temperature is usually the outside ambient temperature. If the temperature of the delivered goods is not the ambient temperature, and the goods are loaded into the compartment, the ambient temperature will affect the temperature of the delivered goods, resulting in changes in the quality of the delivered goods. Therefore, the carriage must be pre-cooled to the required temperature before loading.

2. The refrigeration unit must be turned off when loading and unloading the refrigerated truck

  When we pre-cool the car, if we do not shut down the car and open the car door, because the fan of the evaporator of the refrigeration unit is working, the front of the fan is positive pressure, and the back of the fan is negative pressure, so the cold air is blown out from the upper part of the car, and The lower part will quickly suck in the hot air from the outside, which will cause the temperature in the cabin to rise rapidly; if the cargo is loaded and unloaded after the machine is turned off, because the fan is stopped, the air flow will stop, and the wind pressure inside and outside the cabin will be the same, so that the external hot air is transferred into the cabin. The speed in the car is relatively slow.

3. The refrigerated truck and the evaporator export strictly stack the goods

  When loading, do not stack the cargo too high, make sure that the loading height is not higher than the plane height of the air outlet, and maintain a minimum distance of 225 mm between the top of the cargo and the roof of the vehicle. If the front of the air outlet is blocked by the goods or 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. Because the air outlet is blocked by the cargo, the cold air (or hot air) cannot be circulated normally in the cabin, thus increasing the local temperature of the cargo.

4. Refrigerated trucks are strictly mixed with goods with different temperatures

  Goods with different temperatures are strictly prohibited to be stored in the same compartment. If the conditions are limited, it must be shipped with the vehicle and should be placed separately with a sealed partition. Since the freezer is used to maintain the temperature of the goods, not to cool them down, the mixing of goods with different temperatures will affect the temperature of the goods and affect the quality of the goods.
