The difference and advantages of dry ice and other refrigerants

 

Before the dry ice has not been widely promoted, it is generally used as a refrigerant based on liquid nitrogen. Liquid nitrogen has a boiling point of -196°C, which is mainly used in industrial and medical applications. The use of dry ice is more and more extensive, which shows that in terms of refrigeration, dry ice is obviously superior to liquid nitrogen.

 

1.Dry ice is easy to use, saving costs

The non-mechanical refrigeration and refrigerated container system with dry ice as the cold source is to achieve the purpose of cooling by using the large vaporization latent heat and the lower vaporization temperature when the dry ice is sublimated.

 

2. The cold source storage room is fast filling and easy to use:

The snowflake-shaped dry ice in the cold source storage chamber is formed by decompressing the high-pressure liquid carbon dioxide through the decompression device, and the filling speed is faster, which is much shorter than the cold plate cold storage time of the cold plate type reefer container.

 

3.Dry ice is convenient and flexible to use, and mechanical cooling and cooling speed is fast:

Because the dry ice is cooled by the dry ice sublimation process, the cooling speed is fast, and the vaporization amount of the dry ice can be adjusted conveniently through the temperature regulation system inside the box, so that it can be used in a short time.

 

It can be seen from the above that dry ice has a greater advantage than refrigerants such as liquid nitrogen in refrigeration. Not only in refrigeration, but also in the fields of transportation and preservation, food processing and equipment cleaning, dry ice has a wide range of applications. With the continuous development of society, dry ice will exert its great potential in the future development.
