B.
Where there is a room division but there is an opening
between the rooms sufficiently large to permit a free flow of air
back and forth.
(Where there is an opening without a door or where there are open-
ings above and below the door which are each equivalent in size to
0.15% or more of the floor area.)
3.
Calculating the refrigerant density using the results of the calcula-
tions in steps 1 and 2 above.
If the result of the above calculation exceeds the maximum concen-
tration level then make similar calculations for the second then third
smallest room and so until the result falls short of the maximum con-
centration.
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.
Please consult your Daikin supplier.
