Abstract

The invention relates to the technical field of low-temperature storage equipment, and particularly provides a low-temperature storage box and a control method thereof. The low-temperature storage box comprises a box body, a refrigerating system is arranged in the box body and comprises an air duct structure, a first air duct and a second air duct are arranged in the air duct structure, a first evaporator, a first fan, a first cold storage device and a first heating device are arranged in the first air duct, and a second evaporator, a second fan, a second cold storage device and a second heating device are arranged in the second air duct. The first cold storage device is arranged between the first evaporator and storage space of the box body, and the first heating device is arranged close to the first evaporator. The second cold storage device is arranged between the second evaporator and the storage space of the box body, and the second heating device is arranged close to the second evaporator. The requirement that the temperature in the low-temperature storage box is basically constant during evaporator defrosting can be met.

Description

technical field [0001] The present invention relates to the technical field of low-temperature storage equipment, in particular to a low-temperature storage box and a control method thereof. Background technique [0002] The cryogenic storage box is used to provide a low temperature environment to store plasma, vaccines, biological materials and products, special medicines, etc. [0003] During use, it is necessary to defrost the evaporator of the low-temperature storage tank periodically or irregularly. However, the existing defrosting method is generally to shut down the refrigeration system of the low-temperature storage tank, and simultaneously heat the evaporator briefly. This common method of heating and defrosting has a great influence on the temperature of the inner space of the storage box, so that the product cannot be kept within the set temperature range. Especially for some materials or products with extremely strict temperature requirements, even a short temp...
