Dear all,

I am currently working on a project with a VRF system. We have contacted the manufacturer for non-default refrigerant leakage rate values. The value obtained of 3.13grams/year would mean almost 0% leakage rate per year.

Should I use the manufaturer's value for the calculation or is 0.5% the minimum value allowed? This make a considerable difference in the calculation.

Thanks in advance.
