Step 3: Calculating the refrigerant density using the results of the calculations in steps 1 and 2 above.
Total volume of refrigerant in the
refrigerant system
≤
Maximum concentration level (lbs./ft.
3
)
Size (ft.
3
) of the smallest room in which
there is an indoor unit installed
If the result of the above calculation exceeds the maximum concentration level then make similar calculations for the second
then third smallest room and so until the result falls short of the maximum concentration.
Step 4: Dealing with the situations where the result exceeds the maximum concentration level.
Where the installation of a facility results in a concentration in excess of the maximum concentration level then it will be necessary to revise
the system.
