Intent 1:
To limit the probability that:
- the outdoor air supply from a heat recovery ventilator
will exit a building through another heat recovery ventilator that
is not operating, which could lead to an inadequate distribution of
fresh air to the intended rooms or spaces, or
- the airflow of another heat recovery ventilator will
be disrupted.
This is to limit the probability of
inadequate ventilation, which could lead to the inadequate control
of:
- airborne pollutants,
- oxygen and other components necessary for breathable
air, or
- relative humidity, which could lead to condensation,
which could lead to the generation of pollutants from biological growth
or from materials that become unstable on wetting.
This is to limit the probability of negative effects on
the air quality of indoor spaces, which could lead to harm to persons.
