R227ea
Heptafluoropropane is a new type of efficient fire extinguishing gas, which has the characteristics of colorless, tasteless and strong insulation, and is not easy to cause secondary pollution in the process of fire extinguishing. It is widely used in the field of fire fighting.
R236cb
Widely used in new refrigeration equipment (ultra-low temperature, deep cold) in the process of initial installation and maintenance of re add.
R290
A colorless odorless flammable gas alkane with three carbon atoms, molecular formula ch3ch2ch3, melting point - 189.7 ℃, boiling point - 42.1 ℃, relative density 0.5853 (- 45 / 4 ℃), refractive index 1.2898, heavier than air, often staying in low place, forming explosive mixture with air, explosion limit 2.4% - 9.5% (volume), easily soluble in ether, soluble in alcohol, benzene and chloroform, slightly soluble in acetone, insoluble in water However, it is easy to form solid hydrate with water at low temperature, which causes the blockage of natural gas pipeline. The critical temperature is 96.8 ℃, and the critical pressure is 4.24mpa. Chemical properties are not active, but halogenation and other reactions can occur. It exists in oil pyrolysis gas and natural gas.
R406a
R406a mixed refrigerant is a mixture of HCFC-22, hcfc-142b and R-600a. It is a colorless gas at room temperature and a colorless transparent liquid at its own pressure. It is an alternative to R500 and R12. It is superior to R12 in environmental protection, energy saving and refrigeration volume, and can directly replace R12, but the power consumption will increase by 18%.
R407c
R407C is composed of R32 refrigerant and R125 / refrigerant plus R134a refrigerant in a certain proportion. It is an environmentally friendly refrigerant that does not damage the ozone layer
R409a/b
R409a/b is a mixture of refrigerant R22, r124 and R142b. It is a colorless gas at room temperature and a colorless transparent liquid at its own pressure. It is a substitute of R12 and mainly used in refrigeration system.
R410a
R410A: it is a new type of environmental protection refrigerant, which does not damage the ozone layer. Its working pressure is about 1.6 times of that of ordinary R22 air conditioner, and its refrigeration (heating) efficiency is high. R410A new refrigerant consists of two quasi azeotropic mixtures, R32 and R125, each 50%, mainly composed of hydrogen, fluorine and carbon elements (expressed as HFC), which are stable, nontoxic and excellent in performance. At the same time, because there is no chlorine element, it will not react with ozone, that is, it will not damage the ozone layer. In addition, the performance of air conditioning with new refrigerant will also be improved. R410A has been recognized as the most suitable refrigerant to replace R22 in the world, and has been widely used in Europe, America, Japan and other countries. The global trend and Prospect of R410A replacement in major international markets and the trend of entering the international market.
R415b
R415b is rated as "a national key environmental protection practical technology in 1999" by the State Environmental Protection Administration of China, and it is the substitute of ODS recommended by the State Environmental Protection Administration in 2004.
R417a
R417A is compatible with the existing refrigeration oil and is suitable for the typical R22 direct expansion (DX) system. It is very close to the operating pressure and efficiency of R22, and it is a long-term solution to replace R22, without changing the equipment and system. It is suitable for all kinds of air conditioning and refrigeration units using R22.
R507
R507, like R404A, is an environmentally friendly refrigerant to replace R502, but r507 can usually reach a lower temperature than R404A. R507 is applicable to new commercial refrigeration equipment (supermarket refrigeration cabinet, cold storage, display cabinet, transportation), ice making equipment, transportation refrigeration equipment, marine refrigeration equipment or renewal equipment with medium and low temperature, and it is applicable to all R502 normal operation environments.
