Must be pre cooling and pre heating of the carriage held before loadingBefore loading, must be on the carriage held pre cooling and pre heating 1.5 hours.

Because the vehicle park in the open air, usually the interior temperature is the temperature of the environment, in general the delivery of cargo temperature may be environmental temperature is, do not have necessary refrigerated truck transportation. Cargo compartment, inside the ambient temperature will affect the temperature of transporting goods, which leads to the change of the quality of the delivery of goods, so before loading must be pre cooling compartment to the necessary temperature.Closed refrigeration unit and loading and unloading refrigerator temperature loss more slowlyIn the loading and unloading cargo must close the refrigeration unit, many people in the loading and unloading of goods are not closed refrigeration units, thought that can make the temperature of the goods rose more slowly, in fact, this is a very wrong understanding.If there is no closed refrigeration unit, when open the compartment door, the refrigeration unit evaporator fan in the work, fan the air blowing out from the upper part of the compartment, and the lower part of the hot air outside will quickly sucked, thereby causing the temperature inside the rapid rise; if the shutdown after the loading and unloading of goods, because the fan in a stopped state the carriage stopped, the air flow, internal and external pressure of consistent, outside the hot air enters more slowly.Regular cleaning the refrigerated compartment to keep the car interior cleanCleaning the refrigerated compartment has two functions, one is to keep the car interior environmental health, prevent odor appeared in the carriage. This should be a very good understanding of refrigerated trucks, somewhat similar to the refrigerator, if not pay attention to cleaning, it is easy to smell. Refrigerated trucks often arranged for different goods, especially fish, meat and so on, the best delivery every time the end of a goods is a cleaning car.Another role is to prevent the evaporator fan cooling unit will be sucked into the evaporator coil impurities, thereby reducing the refrigerating effect refrigeration unit, which is why the refrigerator car with everyone will feel the refrigeration effect as one reason well after a few years.Cargo discharge has exquisite place goods need to keep the cabin wind circulation
