Tables for PATTERN 1 and 2
Table 1: Minimum floor area
Take the following into account:
• For intermediate floor areas, use the column with the lower value.
Example:
If the floor area is 1.7 m², use the column of 1.65 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 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.
• (*): The release height of the unit without chimney (minimum 1.95 m) is already higher than the minimum required release height. => OK (no
chimney needed).

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.
