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.
