2.
Calculate the smallest room volume (ft
3
).
Calculate the volume of (A), (B) as a single room or as the
smallest room, as shown in the following diagams:
A.
Where there are no smaller room divisions:
B.
Where there is a room division but there is an opening
between the rooms large enough to permit a free flow
of air back and forth
:
1.
opening between rooms
2.
partition
Where there is an opening without a door or where there
are openings 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
calculations in steps 1 and 2 above.
If the result of the above calculation exceeds the maximum
concentration level then make similar calculations for the
second then third smallest room until the result falls short
of the maximum concentration.
The refrigerant maximum concentration level must not be
exceeded.
when installation results in an excess of the maximum
concentration level it is necessary to reconfigure the sys-
tem.
Please consult your Daikin supplier.
