See table 4:
Look up the minimum bottom opening area for natural
ventilation with the adjacent room (
A
nv-min
) for the given refrigerant charge,
the given floor area of room A (
A
roomA
)
[! NOT room A + room B !]
and the
given release height (
H1
).
Calculate
ΔH1:
difference between the minimum release height
required (
H1
) and the release height without chimney.
See table 2:
Look up the minimum release height (
H1
) for the
given floor area (
A
total
)
and the given refrigerant charge.
Is it practically feasible to
create ventilation openings that comply
with
A
nv-min
and with the
"Conditions ventilation
openings"
on previous page)?
See table 3:
For ΔH1
: Can the maximum
chimney length be respected, and is the
chimney practically feasible?
See table 2:
Do you
need a chimney or not?
(i.e. does table 2 result in a value or "

You can install the unit in room A if you create ventilation
openings. You do not need a chimney.
Ventilation openings must comply with

You can install the unit in room A if you install a chimney, and
create ventilation openings.
