Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cold chain, and particularly relates to a refrigerated container. BACKGROUND

[0002] Vegetables, fruits, flowers, fish, eggs and milk often need to be stored and transported by refrigeration to ensure their quality during transportation. Cold storage pre-cooling and refrigerated container transportation greatly reduce the damage rate of fresh products and improve the freshness of products. The refrigeration unit (including a condenser, an evaporator and a compressor) of the current refrigerated container is generally arranged at the front end of the container body. When the goods are placed inside the container body, the remaining air in the container body moves along the length direction of the container body to the rear end of the container body and returns through the refrigeration unit, forming circulating cold air on the surface of the goods, and then the goods are kept warm. During transportation, the field heat of fruits and vegetables and the respiratory heat generated by themselves cause the temperature inside the goods to rise, accelerating the aging of fruits and vegetables, and ultimately leading to their rotting and deterioration, and the damage rate increases. When goods are transported by using the refrigerated container, the large temperature fluctuation in the refrigerated container will cause the change of the relative humidity of the air in the refrigerated container, and the change of the relative humidity will cause the loss of moisture of the food, forming the dry consumption phenomenon. This dry consumption is proportional to the fluctuation of the temperature. When high-respiratory-heat goods are stored and transported, the goods continuously generate a large amount of heat, and the fluctuation of the temperature will cause the fluctuation of the respiratory intensity of fruits and vegetables. This fluctuation of the respiratory intensity is extremely unfavorable for safe storage. The updraft form contacts the rising heat generated by the goods. Due to the large heat, it is difficult for the air in the refrigerated container to form a circulation, the temperature uniformity in the refrigerated container is poor, the heat is gathered in the container body, the goods are damaged due to over-temperature, and the damage rate is high during transportation.
