The minimum opening area for natural ventilation between room A
and room B is calculated by the following formula:
A

Where:

• A
: room A area, in m

roomA
• m
: the allowable maximum refrigerant charge in the
max
room A, in kg.
• Mark "-" in the above table indicates that the room A is
large enough for installation without adjacent room B.
• For intermediate refrigerant charges, room A area
and installation height, select the higher charge
value, the smaller room area and the lower height
value to choose the A
