13.3 About the charge limit
The charge limit must be determined separately for each BS unit
branch pipe port.
This is possible because of the shut-off valves in the BS unit. The
maximum amount of refrigerant that can escape in case of a leak is
determined by the piping length and indoor heat exchanger size.
This is directly linked to the downstream indoor unit capacity of this
piping section.
In case a leak is detected in an indoor unit, the shut-off valves in the
BS unit of the respective port will close. The piping section with the
leak is now shut off from the rest of the system and the amount of
refrigerant that can leak is significantly reduced.
Note: When two branch pipe ports are combined in order to form a
single branch pipe port (e.g. FXMA200/250), they must be
considered as a single branch pipe port.
13.4 To determine the charge limit
Step 1 – In order to derive the total refrigerant charge limit in the
system, determine the area
▪ of the rooms where an indoor unit is installed,
▪ AND of the area of the rooms served by a ducted indoor unit
installed in a different room.
