Abstract
Description
Technical Field
[0001] The invention relates to the technical field of temperature control of animal husbandry and veterinary equipment, and in particular to a low-temperature regulating and storing system for animal husbandry and veterinary vaccines. Background Art
[0002] With the development of animal husbandry, vaccines play a vital role in the prevention and control of animal diseases. In order to ensure the activity and effectiveness of vaccines, it is very important to maintain a suitable storage temperature. Most vaccines are extremely sensitive to temperature. Slight fluctuations in storage temperature may affect their effectiveness and even cause the vaccine to fail. Therefore, low-temperature storage systems are widely used in the animal husbandry and veterinary fields to ensure vaccine quality. However, when existing low-temperature storage systems handle the simultaneous storage of multiple vaccines, uneven temperature stratification often occurs, that is, the temperatures in the upper and lower layers of the storage space are inconsistent, making it difficult to ensure that the temperature in each area is within the ideal range. This problem is particularly prominent when vaccines have strict temperature requirements.
[0003] The main problem faced by the existing technology is that the uneven temperature stratification and centralized temperature control are difficult to meet the precise temperature requirements of different vaccines. When multiple vaccines are stored in the same storage space, the existing low-temperature storage system cannot achieve independent temperature control for each vaccine, resulting in overcooling or overheating in some areas, which in turn affects the effectiveness of the vaccine. In addition, the uneven temperature also increases the energy consumption of the system and reduces the storage efficiency. Therefore, there is an urgent need for a low-temperature regulating storage system that can effectively solve the uneven temperature stratification and realize independent temperature control in multiple partitions to ensure that different vaccines are safely stored at their appropriate temperatures and improve the accuracy and energy efficiency of the storage system.
