Proper storage of temperature sensitive items is crucial in multiple industries and research fields. Chongqing Chuangce Low Temperature Storage Box provides an adaptive solution for such storage needs.
1、 Structural construction
•Box material and designThe exterior of the box is made of high-strength metal materials such as cold-rolled steel plates, which are collision resistant and wear-resistant; The interior is made of stainless steel material, which is corrosion-resistant and easy to clean. The double-layer sandwich is filled with polyurethane foam and other thermal insulation materials to reduce the external heat transfer, maintain the low temperature stability in the box, and reduce energy consumption.
•Box door and sealThe box door is thick and equipped with high-quality rubber sealing strips, which maintain elasticity at low temperatures and tightly fit the box body to prevent cold and heat exchange; Some models come with automatic door closing devices to prevent temperature stability from being affected by the door not being tightly closed.
•internal layoutAdopting adjustable height multi-layer shelves to adapt to different specifications of items; Medical and scientific research models are equipped with dedicated zones (such as blood sample sorting zone and reagent bottle slot zone) for easy classification and storage, reducing the risk of collision and damage to items.
2、 Refrigeration principle
•Refrigeration cycle systemRelying on the reverse Carnot cycle operation, the continuous cooling and temperature maintenance inside the box are achieved through four processes: compression by the compressor, liquefaction by the condenser, throttling and cooling by the expansion valve, and heat absorption and vaporization by the evaporator.
•Application of refrigeration technologyConventional low-temperature scenarios use a single-stage refrigeration system; When lower temperatures are required (such as for special biological samples or drug storage), cascade refrigeration technology is used to expand the temperature range by coordinating multiple refrigerants.
3、 Temperature control technology
•Sensors and Feedback MechanismsEquipped with high-precision sensors such as PT100 platinum resistors, the temperature inside the box is monitored in real time and fed back to the control system. The system compares the preset value with the actual value and promptly initiates adjustment measures.
•PID control algorithmBy using PID algorithm to control the cooling and heating system (some models include heating function), increase the cooling capacity when the temperature is too high, reduce the cooling or start heating when the temperature is too low, reduce temperature fluctuations, and achieve stable temperature control.
•Anti interference measuresOptimize control algorithms to quickly adapt to disturbances, enhance the insulation performance of the enclosure, set buffer spaces to reduce cold air loss during door opening and closing, and cope with external disturbances such as frequent door opening and environmental temperature changes.
4、 Application scenarios
•medical fieldUsed for storing blood, serum and other samples in hospital laboratory departments to ensure testing accuracy; Provide a stable low-temperature environment for mRNA vaccines, biologics, special antibiotics, and other drugs to maintain their activity and effectiveness.
•research fieldStore biological samples such as cells, tissues, and DNA to prevent structural damage to biomolecules; Long term preservation of microbial samples such as viruses and bacteria to support genomics, epidemiology, and other research.
•food sectorSave ingredients such as caviar and truffles to maintain freshness and taste; Storing fermentation strains to ensure stable fermentation during food processing; Extend the shelf life of food additives and nutritional fortifiers to ensure product quality.
Chongqing Chuangce Low Temperature Storage Box, with its reasonable structure and reliable refrigeration and temperature control technology, provides strong support for the storage of temperature sensitive items in multiple fields, meeting the diverse needs of different industries.
