Analysis of common misunderstandings about setting temperature of refrigerated trucks

Date of release:2019-04-12 Author: Click:

The temperature control in the refrigerated truck determines the freshness of the goods. In general, users need to pay attention to the temperature setting of the thermostat and the pre-cooling or pre-heating of the refrigerated compartment. But in practice, many people have misunderstandings. van


 


First of all, it is the setting of the temperature of the thermostat. The user needs to set the thermostat to the required temperature, pre-cool the car for 1.5 hours to remove the heat trapped in the car; turn off the refrigeration unit when loading, and quickly load the cargo.


In addition, the carriage must be pre-cooled or preheated before loading. Since 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.

Many users have misunderstandings in operation, such as: they do not turn off the refrigeration unit when loading and unloading goods.


Reason analysis: If the car is not turned off after pre-cooling, when the door of the car is opened, since 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, while the bottom is at the bottom. The external hot air will be sucked in quickly, 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 stops, and the air pressure inside and outside the cabin is the same, so that the external hot air is transferred into the cabin. The speed is relatively slow.
