Caution for Refrigerant Leaks
General Information

Step 2:
Calculate the smallest room volume (m
3
).
In a 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.)
(c) Where there is a gas leak detection alarm device linked to a mechanical ventilator in the
smallest room then the next smallest room will become the measurement target.
Step 3:
Calculate the refrigerant density using the results of the calculations in Step (1) and (2)
above.
If the result of the above calculation exceeds the dangerous concentration level then make
similar calculations for the second then third smallest room and so on until the result falls short
of the concentration level.
