First of all, let us realize that not cold storage refrigerator car, the function of the refrigeration unit is warm. In the minds of many people, the refrigeration device on the refrigerator can refrigeration or heating the inside cargo to the necessary temperature. In fact, refrigeration unit is used to keep the temperature of the goods, rather than lower the temperature of the goods. Which is similar to the past selling cold drinks quilt. Pack it to keep the temperature of the cold drinks. When the ambient temperature by radiation, conduction and convection, into the refrigerator, the refrigeration unit blowing out cold air, isolation of heat into the goods, ensure the temperature of the goods.

Need the goods is necessary transportation temperature, otherwise it goes bad.

If the temperature is too high or too low loading of the goods of refrigerator car, and then set refrigeration unit to transport goods needed for the transportation temperature, the temperature of the goods will be in a certain period of time to reduce or increase to the desired temperature. In this way, the opposite can be true. The goods will not damage by temperature drop (or higher) or deterioration.

Refrigeration unit to blow out of the air conditioning will change the temperature of the goods, goods lose moisture, resulting in the change of the quality of the goods, led to the decrease of the quality of the goods, the storage life shorten, even bad.

Very likely you fresh beans arrived at the destination will be more "dry", will reduce a lot of weight, cause trouble. This is why the refrigerator car usually go to the fridge to pull goods, but rarely direct cargo to the field.

After understanding the function of the refrigerator, hope the broad masses of refrigerator car users can correct use refrigerated trucks, guarantee the quality of cargo.
