How do ultra-low temperature freezers work?

This year, the medical ultra-low temperature freezer that meets the need of vaccine storage and transportation will face a severe shortage in short-term. The digital ultra-low degree freezer is the basis for the realization of vaccine cold chain transportation, and this is all due to its superior working parts, which together construct a complete refrigeration constant temperature system for the ultra-low temperature freezer.

What can be put in the medical ultra-low temperature freezer?

The inner box of the ultra-low temperature freezer is generally divided into multiple bearing layers, and each layer is designed with an inner door that can be opened and closed independently. The outer box is generally formed by directly splicing cold-rolled steel plates.

The digital ultra-low degree freezer interior has many components, including a compressor that compresses low temperature vapor into gas. A heat dissipation component that cools high temperature and high-pressure gas into liquid through heat exchange. These two are the core components of the medical ultra-low temperature freezer.

Among them, the sensor of the digital ultra-low degree freezer is used for temperature control. Due to its harsh working environment, highly sensitive materials must be selected. Fluorine free refrigerants are generally selected to meet environmental protection requirements.

The filter drier of the medical ultra-low temperature freezer can absorb the refrigerant and the moisture and impurities in the system pipeline to keep the system dry and clean. The capillary tube is throttling through resistance, turn high temperature and high-pressure liquid into low temperature and low-pressure liquid.

The evaporator of the medical ultra-low temperature freezer can evaporate liquid from the capillary tube into gas through heat exchange with the outside. The accumulator separates the liquid in the refrigerant gas entering the compressor.

 

How to use medical ultra-low temperature freezer correctly in labs?

The refrigeration system of medical ultra-low temperature freezer generally uses secondary refrigeration. When the panel temperature is higher than the set temperature, the primary refrigeration starts and the condenser temperature of the secondary refrigeration system drops.

The evaporator of the secondary refrigeration system is on the inner wall of the medical ultra-low temperature freezer, which can reduce the internal temperature. The heat is absorbed by the evaporator of the primary refrigeration system, and the heat of the primary condenser will be dissipated into the air.

 

What is the trend of use of medical ultra-low temperature freezer?

In addition to the stability and uniformity of the medical ultra-low temperature freezer itself, proper maintenance and management can also help improve the refrigeration effect of the medical ultra-low temperature freezer, and can ensure the durability of the medicines and prevent the items from interacting and causing toxicity.

  • Periodic inspection

The management of the medical ultra-low temperature freezer should arrange for special personnel to be responsible for regular inspection, regular cleaning and regular maintenance. The head nurse regularly conducts spot checks to ensure How to use medical ultra-low temperature freezer to complete daily work is in good working condition.

  • Reasonable classification

Articles placed in the medical ultra-low temperature freezer should be classified according to the type and nature of the articles, and the injections, internal medicines, and external medicines should be categorized and stored, and eye-catching signs should be affixed.

If there are scientific research supplies, they should be placed in a clean container and placed in the refrigerator, and clearly marked. In addition, it is strictly forbidden to place personal belongings in the medical ultra-low temperature freezer.

  • Rules and regulations

Formulate relevant management systems and specifications for digital ultra-low degree freezer, and clarify the purpose and requirements of refrigerator management.

Strengthen health education and increase the pass rate of medical staff washing hands. At the same time, the medical ultra-low temperature freezer should be cleaned and disinfected regularly to ensure the safety of patients' medication.

 

As a manufacturer committed to building a high-standard vaccine cold chain logistics system, providing mature solutions for pharmaceutical cold chain products, and complying with digital ultra-low degree freezer qualification specifications, Meibaijia Electrical Technology Co., Ltd. hopes to answer your doubts through the analysis of ultra-low temperature freezer working principle.
