When reviewing the 2020 global air conditioner market trends, it emerges that the shift to mildly-flammable (A2L) refrigerant R32 continues to accentuate and is becoming more far-reaching, in spite of the significant impact exerted by the COVID-19 pandemic. The global air conditioner market in both the residential and commercial sectors is estimated to have decreased by nearly 10% in 2020 compared with 2019. On the contrary, demand for R32 air conditioners is estimated to have increased by about 10%.The number of countries where R32 units account for the majority of the split-type room air conditioner (RAC) market is increasing, mainly in Asia, Europe, and Oceania. The penetration of R32 units in the entire global split-type RAC market including Japan is estimated to have reached over 50% in 2020.

A new peer-reviewed study published in Atmospheric Chemistry and Physics simulated rainwater concentrations of trifluoroacetic acid (TFA) from the degradation of projected HFO-1234yf usage in India, China, and the Middle East through 2040. The study affirms that TFA from HFO-1234yf refrigerants has a negligible effect on human and ecosystem health. This is consistent with findings of previous studies focused on the U.S., Europe, and China. Even in scenarios envisioning the largest emissions of HFO-1234yf through 2040, TFA rainwater concentrations remain orders of magnitude below the no observable effect concentrations (NOECs) in ecological and mammalian toxicology studies. The study completes our knowledge on the human and ecological impact of TFA from HFO-1234yf for the most populated and high economic growth regions in the world.
