Total room area
(a)
All other floors (=All other floors)
(b)
Lowest underground floor (=Lowest underground floor)
When total floor area A
3
is determined, use the graph or table above to determine
the total refrigerant charge limit in the system. For A
1
and A
2
, use the graph or
table from the outdoor unit installation manual.
Note:
When multiple outdoor units are serving the same space, calculate the room
area based on the outdoor unit with the largest refrigerant charge.
Note:
The factory charge depends on the outdoor unit in the system. The examples
used below consider a VRV 5-S R32 outdoor unit.
Note:
Make sure the total refrigerant charge amount is lower than:
▪
15.96 kg x the total number of connected indoor units and EKVDX units.
▪
63.84 kg.
Case 1: VAM+EKVDX and indoor unit(s) combined
Step 1
– determine:
▪
A
1
– the area of the smallest room in the lowest underground floor in which an
indoor unit is present (if applicable). See outdoor unit installation manual.
▪
A
2
– the area of the smallest room not in the lowest underground floor, in which
an indoor unit is present. See outdoor unit installation manual.
▪
A
3
– the total area of all the rooms which the EKVDX is discharging air into. See
"3.1.3 To determine the floor area"
Note:
The EKVDX can be discharging into the same room as a normal indoor unit.
The area of this room must also be taken into account for A
3
.
