13.4.3 Natural ventilation
Natural ventilation is a safety measure where ventilation is made to a
place where sufficient air is available to dilute the leaked refrigerant
such as a large space.
The natural ventilation safety measure can be applied by following
the steps below:
Step 1 – Determine total room area, which is the total area of the
space that has natural ventilation and the space in which the indoor
unit is installed/conditioning:
The respective room area can be determined by projecting the walls,
doors and partitions to the floor and calculating the enclosed area.
Spaces connected only through false ceilings, ductwork, or similar
connections are not considered a single space.
Step 2 – Use the graph or table below to determine the total
refrigerant charge limit:

min
Minimum room area of the space in which the indoor unit
is installed/conditioning [m²]
Note: Round down the derived values.
The graphs and table are based on an installation height of the
indoor unit up to 2.2 m (bottom of indoor unit or bottom of duct
openings).
If the installation height is more than 2.2m, higher total refrigerant
charge limit of the system can apply. To know the total refrigerant
charge limit of the system in case the installation height is more than
2.2m, refer to the online tool (VRV Xpress).
Step3 – The total amount of refrigerant in the system MUST be less
than the refrigerant charge limit derived from the graph above. If
NOT, natural ventilation safety measure is not allowed.
Step4 – The partition between two rooms on the same floor MUST
meet one of the following two requirements for natural ventilation.
1 Rooms on the same floor that are connected with a permanent
opening that extends to the floor and is intended for people to
walk through.
2 Rooms on the same floor connected with permanent openings
that fulfil the requirements listed below. The openings must
consist out of two parts to allow air circulation for natural
ventilation.

WARNING
The ventilation openings MUST NOT be blocked.
For the lower opening:
▪ It is not an opening to the outside
▪ The opening cannot be closed
▪ The opening must be ≥0.012m² (A
nvmin
)
▪ The area of any openings above 300mm from the floor does not
count when determining A
nvmin
▪ At least 50% of A
nvmin
is less than 200mm above the floor
▪ The bottom of the lower opening is ≤100mm from the floor
▪ The height of the opening is ≥20mm
For the upper opening:
▪ It is not an opening to the outside
▪ The opening cannot be closed
▪ The opening must be ≥0.006m² (50% of A
nvmin
)
▪ The bottom of the upper opening must be ≥1500 mm above the
floor
▪ The height of the opening is ≥20mm
Note: The requirement for the upper opening can be met by false
ceilings, ventilation ducts or similar arrangements that provide an
airflow path between the connected rooms.
NOTICE
Indoor units and the bottom of duct openings cannot be
installed lower than 1.8m from the lowest point of the floor,
except for floor standing indoor units (e.g. FXNA)
Example
The total amount of refrigerant in the VRV system is 20kg. The VRV
system has two indoor units which are installed in a space that does
not belong to the lowest underground floor of the building. The space
in which the indoor units are installed has a room area of 25m². An
adjacent room has a room area of 45m² to which air circulation is
possible through a partition that meets one of the two requirements
