Intent 1:
To limit the probability that:
- condensation will accumulate in exhaust ducts when temperatures
are above the freezing point, or
- accumulated condensation will freeze in exhaust ducts
when temperatures are below the freezing point, which could lead to
the buildup of ice in the ducts, which could lead to ducts being blocked,
which could lead to inadequate ventilation.
This is to limit the probability of
the inadequate control of relative humidity or indoor air temperatures,
which could lead to the inadequate thermal comfort of persons, which
could lead to harm to persons.
