•
If AHU kit is included among the indoor units, you must add 0.0
18
kg
(0.04lb)
of refrigerant for every 1
MBH
of
AHU
capacity increase.
Note1) In case the capacity conjunction of the Hydro Unit HT exceeds 50% among the total indoor unit,
please
don’t put the additional refrigerant.
•
Method to calculate total amount of additional refrigerant
– Amount of additional refrigerant depending on th pipe length
(
ⓐ
)
– Amount of additional refrigerant for each indoor
unit
(
ⓑ
) = ∑(Amount of additional refrigerant for each
connected indoor unit)
※
Refer to the table
– Total amount of additional refrigerant =
ⓐ+
ⓑ
※ Sum of total amount of additional refrigerant and the basic amount of refrigerant should not exceed
100kg
(220lb)
. If
the refrigerant exceeds
100kg
(220lb)
, separate the module so that weight of the
refrigerant doesn’t exceed 100kg
(220lb).
Ex> If the outdoor unit’s basic refrigerant amount is
8.7
kg
(19.1lb)
, the total amount of additional
refrigerant(
ⓐ
+
ⓑ
)
should not exceed
91.3kg (220.9lb)
