Medical Low-temperature Refrigerator and Ordinary Refrigerator Difference

Jan 14,2021
Strictly speaking, refrigerators are divided into three categories: household refrigerators, commercial refrigerators and medical refrigerators. Medical refrigerators are further divided into medical drug refrigerators, medical blood refrigerators, and medical freezers. Because different refrigerators have different design standards, there are big differences in their temperature, use, and refrigerating principles.
 
I. Different Temperature
1. The minimum temperature of ordinary refrigerators is minus 18 degrees, which is the national standard minimum guaranteed temperature of household refrigerators.
2. Common medical low-temperature refrigerators are generally divided into -40 degrees, -90 degrees, -110 degrees, -130 degrees, and -160 degrees. The low-temperature refrigerators produced by various manufacturers will also have different temperature divisions.
 
II. Different uses
1. Ordinary refrigerators are mainly for household use, and are used to refrigerate and keep fresh food.
2. The main purpose of medical low-temperature refrigerators is for scientific research, preservation of medical supplies, low-temperature experiments and storage of special materials such as biological products, oceanic products, electronic components, and chemical materials.
 
III. Different refrigerating principles
1. Ordinary refrigerators have two types of gas absorption type and semiconductor type.
2. The refrigeration system of medical low-temperature refrigerators adopts the working principle of a new generation of single-compressor self-cascade refrigeration technology. Generally, two compressors are used as high- and low-temperature compressors.
 
Medical refrigerators are one of the commonly used equipment in medical institutions and scientific research institutions. The choice of refrigerators is directly related to the safety and effectiveness of clinical testing and clinical blood use. If you use household or commercial refrigerators to store those medical samples, reagents and blood, there are great hidden dangers. Meanwhile, hospitals will also choose medical drug refrigerators, medical blood refrigerators, and medical freezers according to different uses. This means that ordinary household and commercial refrigerators cannot replace medical refrigerators, which is the biggest difference between the two.
