Description

DESCRIPTION LU502562 VEHICLE-MOUNTED MULTI-TEMPERATURE AUTOMATIC CO-DISTRIBUTION REFRIGERATOR

TECHNICAL FIELD The invention relates to the technical field of cold chain transportation, in particular to a vehicle-mounted multi-temperature automatic co-distribution refrigerator.

BACKGROUND Cold chain logistics generally refers to a systematic project in which refrigerated and frozen foods are always in a prescribed low-temperature environment from production, storage, transportation and sales to consumption, so as to ensure food quality and reduce food loss. In the cold chain process of food and medicine, heat preservation and moisture preservation transportation is the most basic requirement for transportation vehicles, and it is also a common problem to be solved.

To solve the above problems, at present, the Chinese patent with the patent number of CN208149984U discloses an intelligent cold chain distribution box. The key point of the main technical scheme is to use a single small box to realize heat preservation alone. However, in the case of large freight volume, taking goods will affect other goods, and it is difficult to realize unified temperature control management for most goods, and it is difficult to accurately monitor the temperature and humidity changes of each box and timely and effectively control them. The Chinese patent with the patent number of CN208036074U discloses a cold chain car. The key point of the main technical scheme is that the car can realize the automatic control of multiple independent temperature zones for refrigerated transportation, but it can't realize the intellectualization of picking up goods.
