Table 2: Minimum release height
Take the following into account:
•
For intermediate floor areas, use the column with the lower value. Example: If the floor area is 5 m², use the
column of 4.00 m².
•
For intermediate refrigerant charges, use the row with the higher value. Example: If the refrigerant charge is
2.35 kg, use the row of 2.4 kg.

Table 3: Minimum bottom opening area for natural ventilation
Take the following into account:
•
Use the correct table. For intermediate refrigerant charges, use the table with the higher value. Example: If the
refrigerant charge is 2.34 kg, use the table of 2.4 kg.
•
For intermediate floor areas, use the column with the lower value. Example: If the floor area is 5 m², use the
column of 4.00 m².
•
For intermediate release height values, use the row with the lower value. Example: If the release height is
2.20 m, use the row of 2.05 m.
