Compressed air is used for refrigeration and gas separation. The gas is compressed, cooled and expanded to liquefy. It is used for artificial refrigeration (freezing, refrigeration and air conditioning), such as ammonia or freon compressors. This type of compressor is usually called " "Refrigerator" or "Ice Machine". In addition, if the liquefied gas is a mixed gas, the components can be separated in the separation device to obtain various gases of qualified purity.

For example, after air is liquefied and separated, pure oxygen, pure nitrogen and pure other rare gases can be obtained. At present, in the petrochemical industry, the raw material gas-petroleum cracked gas is separated by first compressing, and then using different cooling temperatures to separate the components. Compressed gas is used for synthesis and polymerization In the chemical industry, gas is compressed to high pressure, which is often advantageous for synthesis and polymerization.

Compressed gas is used in the petroleum industry. Gas transportation The compressor used to transport gas with pipelines is convenient for gas transportation after pressurization. The pressure depends on the length of the pipeline and the composition of the conveying gas.

The country advocates energy-saving, energy-saving and environmental protection, and standardizes the energy efficiency grading system for air compressor equipment. Level 3 energy efficiency access, level 2 energy efficiency popularization, level 1 energy efficiency and energy saving, and the production of level 1 energy efficiency air compressors will be domestic air compressors. The tireless pursuit and mission of production enterprises. The energy efficiency rating of the air compressor is the energy efficiency ratio, the energy efficiency of level 1 is the highest and the most energy-saving, the second level is second, and so on! Energy efficiency label is a kind of information label attached to the product, used to indicate the energy efficiency grade and energy consumption of energy-using products.
