Ultra-low temperature cold storage

Ultra-low temperature cold storage

Ultra-low temperature temperature design range is generally -40 ℃ ~-120 ℃, mainly used in tuna, seafood, medicine, food, scientific research and other fields of use, at very low temperatures, scientific research to effectively preserve these products, to prevent material deterioration, such cold storage construction requirements are very strict, more common is the coastal areas of tuna ultra-low temperature cold storage.

First, the application range of ultra-low temperature cold storage

1, food storage: used to store tuna, swordfish, swordfish and other expensive and long-term preservation of seafood products, as well as frozen meat, ice cream, frozen food and so on. Ultra-low temperature environment can effectively inhibit the growth of microorganisms and maintain the freshness and nutritional value of food.

2, medical products: used to store vaccines, blood products, cell samples and other biological products to ensure their stability and safety at extremely low temperatures.

3, scientific research: used to store biological samples, genetic materials and other scientific research experimental samples, to provide reliable storage conditions for scientific research.

Second, the construction characteristics of ultra-low temperature cold storage

1, with a low cooling capacity, can maintain the cold storage in a low temperature environment, to prevent product deterioration, usually the construction scale is relatively small, ultra-low temperature cold storage refrigeration system and technical requirements are higher, the need for professional operation and maintenance.

2, the use of cascade refrigeration units, these units through the compressor, condenser, evaporator and other components work together to achieve the refrigeration cycle, the heat in the cold storage to the outside world, so as to achieve the purpose of cooling.

3, ultra-low temperature cold storage unit temperature operation, although the refrigeration system consumes a lot of energy, but the modern ultra-low temperature cold storage design pays attention to energy saving and emission reduction, the use of environmentally friendly refrigerant and efficient refrigeration technology.

4, polyurethane insulation board can effectively heat insulation, insulation, cold resistance, anti-corrosion, according to different temperature selection of thickness, common cold storage board thickness of 10/12/15/20cm thickness, can effectively reduce the loss of cold storage.

Third, the construction cost of ultra-low temperature cold storage

Construction of ultra-low temperature cold storage usually sampling ceiling type chiller, aluminum row evaporator, polyurethane insulation board to build the library, Germany imported refrigeration units, the construction of 100 square meters of about 200,000 costs, such as low temperature -80 ° C biobank, the cost of about nearly 10,000 yuan per square meter, Usually need to calculate the actual size of ultra-low temperature cold storage, temperature, division, construction site, configuration and other factors, if you have needs, welcome to call Leng Di refrigeration for details.
