R-410a or R-32?

[Yellowtail]

Thinking about replacing a couple of old AC units and need to decide which refrigerant to go with.

 

Have read a bit on it and I am undecided. Apparently R-32 is supposed to be the new standard, but I am not sure if it is really better and no idea how common it is in Thailand.

 

Thoughts?

My thoughts would be you think too much go with whatever refrigerant comes with the AC unit you buy.

The units I am considering are available in either, with R-32 costing a couple a little more.

R32 doesnt make holes in the ozone!!

If you're a tree hugger go with the more expensive gas. ????

R-410a does not make holes in the Ozone either, but there are claims R-32 is more energy efficient and easier on the compressor...

R-410A has a GWP (Global Warming Potential)  of 2,090 R-32 has a GWP of 675.

So 1 kg of R-410A is equal to 2,090 kg of carbon.

 

You should be careful not to release either but R-32 is less bad.

 

R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate

 

 

Easier to recycle than R410A, as R32 is a single component refrigerant

Thanks, I read all that. 

 

Do you have any experience with either?

To think long term, go for R32 in case of R410A phases out. I doubt you can feel the difference. Phasing out part is inevitable in my opinion.

I’m not a refrigeration technician. ???? 
 

I do not need to be to know that R32 is better, or at least less bad, than R410A.
 

You have to judge if the savings on running costs will be more than the extra cost of the unit.
