Intent 1:
To limit the probability that an inadequate resistance
to moisture or corrosion will lead to condensation in ducts, which
could lead to the deterioration and collapse of ducts, which could
lead to a reduction in airflow, which could lead to:
- the inadequate control of:
- relative humidity or indoor air temperatures,
- surface temperatures, or
- air velocity,
- the inadequate delivery of warm air or the return of
cold air, which could lead to an inability to maintain adequate indoor
air temperatures, or
- inadequate ventilation, which could lead to the inadequate
control of:
- relative humidity, which could lead to condensation,
which could lead to the growth of mould and mildew, or
- airborne pollutants.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
and
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
