3.1.2 About the minimum floor area
WARNING
If appliances contain R32 refrigerant, then the floor area of
the room in which the appliances are installed, operated
and stored must be larger than the minimum floor area.
This applies to:
▪ Indoor units
▪ Outdoor units installed or stored indoors (example:
winter garden, garage, machinery room)
▪ Field piping in unventilated spaces
To determine the minimum floor area
1 Determine the total refrigerant charge in the system (=factory
refrigerant charge + additional refrigerant amount charged).
2 Determine which graph or table to use.
▪ For indoor units: Is the unit ceiling-mounted, wall-mounted or
floor-standing?
▪ For outdoor units installed or stored indoors, and field piping
in unventilated spaces, this depends on the installation
height:
If the installation height
is…
