The flammability analysis of R32 refrigerant needs to be compared with other refrigerants to have certain reliability. Compared with R290 refrigerant, the ignition energy of R32 is much greater than that of R290. The ignition energy of R32 is about 30 to 100 mJ, while the ignition energy of R290 is maintained at a few tenths. It can be seen that compared to R290, R32 is safer and further reduces the possibility of combustion. This is because R32 refrigerant contains a certain amount of fluorine, which affects its combustibility. Although R32 is less flammable than R290, R32 will also burn if it encounters an open flame, but compared to other refrigerants, R32 has the advantage of being able to automatically extinguish after leaving the open flame.
