Three popular refrigerants, environmentally friendly refrigerant application options

After realizing the harm caused by Freon to the human body and the environment, Freon refrigerants on the market are gradually being replaced by environmentally friendly air-conditioning refrigerants. How should customers choose environmentally friendly refrigerants with their own characteristics? The editor has sorted out the following three kinds, let's see who will be your dish!

Refrigerant R32

R32 refrigerant (ODP is 0, GWP is 675). In 2012, a Japanese air-conditioning company took the lead in launching R32 environmentally friendly refrigerant air conditioners. The thermodynamic performance is similar to that of r410a, the filling capacity is 70% of R410A, and the system cooling capacity is higher than R410A, which helps to alleviate power shortages and reduce carbon dioxide emissions. It has set off an energy-saving boom, but the GWP value is too high, and its popularity in China Needs to be improved.

Refrigerant R290

R290 refrigerant (ODP is 0, GWP<20), the refrigerant represented by China, Germany, Sweden and other countries , The latent heat of vaporization is about twice that of R22, and it has good material compatibility. It is compatible with the original system and lubricating oil. It has a relatively broad market in China, but there are still some problems in application.

Refrigerant R436C

R436C refrigerant (ODP is 0, GWP<3), is the national 863 scientific research project patent achievement, from Jiangsu Furui to Ru0026D and production, the density is only about 40% of R22, the cooling capacity per unit mass of refrigerant is larger, the cooling time of the equipment is shortened, and the basic power saving rate can reach 10%-36%. When the refrigerant is replaced in the refrigeration system using R22 , Can be charged directly without modification. At present, it is widely used in Jiangsu and Guangdong provinces, and is actively developing markets nationwide and overseas.

In terms of the scale of replacement, R290 currently has a wider market range. But in terms of the refrigerant itself, according to the standard requirements, the allowable charge of R32 is ten times looser than that of R290, and its application range is wider. However, R32 has problems such as higher GWP value. R436C's GWP<3 is more outstanding than the two, and has a national patent, and the power saving rate can reach 10%-36%. It is an excellent emerging environmentally friendly refrigerant. When customers choose, they need multiple comparisons. Some products are widely used but have many problems, and some have a small market but large potential. Only when they find a refrigerant that truly suits their own business conditions can they be considered worthwhile and become both environmental and economic benefits. The winner of the collection.
