11-2. Procedure for checking dangerous
■ Concentration
Check the dangerous concentration in accordance with steps 1~4 below and take whatever action is necessary.
(1) Calculate the amount of refrigerant(lbs) charged to each system separately.
◆
Where a single refrigerant facility is divided into 2 entirely independent refrigerant systems then
use the amounts of refrigerant with which each separate system is charged. N N N N o o o o tt tt e e e e
Amount of refrigerant added
locally in accordance with the
length or diameter of the
refrigerant piping
(2) Calculate the smallest room volume(ft 3 )
In a case like the following calculate the volume of (1), (2) as a single room or as the smallest room.
1) Where there are no smaller room divisions
Outdoor unit
Indoor unit
2) 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
