It also means components need to be compatible with flammable refrigerants, to ensure they can't be considered an ignition source. What more can we say? Answer: R32 has 3 advantages 1.the R32 has a lower GWP (Global Warming Potential) value which is more friendly to the environment. Toxic substances like hydrogen fluoride and carbon dioxide are created when R32, like all fluorinated refrigerants, is burnt. All of these refrigerants are gradually being replaced by R32 (Energy and eco-friendly). Some of the reasons for the phasing out of R410a are: In addition, the R410a is beginning to cause more harm than good. Yes. 3. Easy to extract. R32 refrigerant has a volumetric capacity of 20% and requires less charging Higher critical temperature Single gas component Low global warming potential compared to R410a Easy development because of saturated pressure Low density Cons: R32 requires precaution because of the high level of toxicity As a straight R410A system replacement, R32 has around 10% more capacity. If released to the atmosphere it can contribute to climate change. R32 is mainly used for the air conditioning of an apartment or house. The likely candidates are R32 (which makes up 50% of R410A), HFO blends, CO 2 and hydrocarbons such as Propane and Butane. If youre interested in switching to an R32 capable AC system, discuss options with your local HVAC expert. R32 vs R410A vs R22 vs R290: Comparison Table Safety issues to be aware of when handling R32. R32 will not ignite if the concentration in the room remains below the lower flammability limit.
