Sentence 9.33.8.1.(1)

Intent 1:

To limit the probability of rupture of piping in heating and cooling systems that are subjected to the excessive pressure or temperature of the heat exchanger medium, which could lead to an inability to maintain the minimum indoor air temperatures [see Sentence 9.33.3.1.(1)], which could lead to condensation.

This is to limit the probability of:

• the inadequate control of temperatures and relative humidity,
• generation of pollutants from biological growth or materials that become unstable on wetting, or
• the deterioration of building elements.

This is to limit the probability of:

• negative effects on the air quality of indoor spaces, or
• the inadequate thermal comfort of persons.

This is to limit the probability of harm to persons.
