Note:
„
Where a single refrigerant facility is divided into 2 entirely independent refrigerant systems then
use the amount of refrigerant with which each separate system is charged.
2. Calculate the smallest room volume (ft
3
)
In case like the following, calculate the volume of (A), (B) as a single room or as the smallest
room.
A. Where there are no smaller room divisions
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 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 and so until the result falls short of
the maximum concentration.
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.
