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:

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.

For the lower opening:

▪ The area of any openings above 300mm from the floor does not
count when determining A
