Refrigerator can be said that no one will be unfamiliar, and in some special industries, the requirements for refrigerators are very high. It is necessary to refrigerate the refrigerator to keep the items fresh. What is the price of the low-temperature refrigerator ? How to choose a low temperature refrigerator? The following decoration home decoration network Xiaobian will give you an answer one by one, for your reference when purchasing.

What is the price of a low temperature refrigerator?

1, low-temperature refrigerator Sanyo MDF-382E, the price of 8,000 yuan, the real-time status monitoring, alarm make the abnormal situation that existed before the failure, the safe storage: alarm system with superior cooling technology to ensure accurate storage temperature, insulation inside the door to prevent Cold air leakage, anti-theft setting: In addition to the standard door lock, the external lock can be added to the new outer door bolt to ensure the safety of precious samples. The olecranon type internal door bolt: the new olecranon type inner door bolt can make The inner door is more closely integrated with the door frame.

2 , Aucma low-temperature refrigerator DW-150W150, the price of 6000 yuan, this low-temperature refrigerator is suitable for research institutes, biological engineering, blood stations, hospitals, disease prevention and control, laboratories, etc. It is used to store red blood cells, white blood cells, skin, bones, bacteria, viruses, semen, biological products, ocean products, etc., low temperature tests of electronic devices and special materials. The temperature inside the box is adjustable from -100 °C to -150 °C. A variety of fault alarms: high and low temperature alarms, sensor failure alarms, etc., to ensure safe use. With remote network control and remote alarm function. Protection functions such as power-on delay and stop interval. Keyboard lock and password protection to prevent arbitrary adjustment of parameters.

 

 

How to choose a low temperature refrigerator?

1. Refrigerant selection: a new generation of hydrocarbon refrigerant

The development of low-temperature refrigerator refrigerants has now reached the stage of new hydrocarbon refrigerants. Hydrocarbon refrigerants have the advantages of energy saving and environmental protection, and are currently the world's more ideal refrigerants. First, the refrigeration efficiency is high, and the hydrocarbon cooling efficiency is 30% higher than that of the ordinary refrigerant . Save energy by about 50%. Second, hydrocarbon refrigerants are natural working fluids, no pollution to the atmosphere, no damage to the ozone layer, and almost zero greenhouse effect. At the end of 2016, the full range of energy-saving core low-temperature refrigerators equipped with hydrocarbon refrigeration systems was the first to receive the China Quality Certification Center ( CQC) No. 001 Energy Conservation and Environmental Protection Certification. Energy-saving performance has been approved by national authorities.

2, cooling mode selection: two-stage self-cascading refrigeration

The cooling method is the core of the low temperature refrigerator. Stability and long life are the most important. Two-stage cascade refrigeration is a well-recognized refrigeration method recognized by the academic community. Almost all ultra-low temperature brands at home and abroad use this refrigeration method. The two compressors of high temperature and low temperature are divided into two parts, each operating under the best working condition, the whole machine runs stably, and the service life of the compressor is greatly extended. With a single compressor refrigeration cycle, in order to achieve -86 ° C, the high pressure side of the system is very high pressure, a compressor is used under extreme conditions, the failure rate is significantly improved, and the service life is greatly attenuated. Just as the BMW 5 is equipped with a single-cylinder engine and is desperately climbing, the entire power system is difficult to guarantee.

3, temperature uniformity: can not see simple numbers

Behind the number of temperature uniformity depends on the detection method. What method is used to detect it. At the same time, it must have the test report of the National Quality Supervision and Inspection Center. The most demanding test method in the industry is to place 20 points in the entire box . The current industry leading indicator is that the temperature uniformity at any point in the box is 7 ° C, which is within ± 3.5 degrees. If it is higher than this indicator, it is likely to be a registration test. There are only 4 test points, and it is the method of taking the average number of tests.

4, accreditation certification: can not only look at the name

Many certifications are marked by a certain ministries and commissions in the country, a provincial and other scientific invention awards, and scientific and technological achievements awards; but these awards are not low-temperature refrigerators. In addition to the name, it is also necessary to pay attention to whether it is a low-temperature refrigerator project, whether there is a phenomenon of false and real.

5, see the market holdings:

Finally, you can also refer to the purchase from the market. The vast majority of users' choices and years of cryogenic storage services highlight the strength of the low-temperature refrigerator brand and the trust of users. Therefore, a brand with a large market share must have a guarantee of its quality and reputation. Like some old low-temperature refrigerators , through ten years of independent innovation, the market can reach 50,000 units. The low-temperature refrigerator brand used by the China Bone Marrow Bank, the National Gene Bank to the Chinese Human Genetic Resources Library, and the biological sample banks of major hospitals is also informative for our purchase.

The above is the price of the low temperature refrigerator brought by Xiaobian. How to choose a low temperature refrigerator?
