Minimum floor area / Release height:
▪
The minimum floor area requirements depend on the release height of the
refrigerant in case of a leakage. The higher the release height, the lower the
minimum floor area requirements.
▪
The default point of release is 100 mm below the top of the unit.
▪
You can also take advantage of the floor area of the adjacent room (= room B) by
providing ventilation openings between the two rooms.
▪
For installations in technical rooms (i.e. room that is NEVER occupied by
persons), additionally to patterns 1 and 2, you can also use PATTERN 3. For this
pattern there are no requirements to the minimum floor area if you provide 2
openings (one at the bottom, one at the top) between the room and the outside
to ensure natural ventilation. The room must be protected from frost.
