A VAV air terminal with hot-water reheat is selected at design so that, at the zone peak sensible load, it can (conceptually) do what in parallel with the central supply SAT reset?

Choices

  • (A) Meet zone sensible + fraction of reheat/ humidity needs without overcooling, subject to min-flow & SAT limits
  • (B) Reject all latent at terminal only
  • (C) Eliminate AHU
  • (D) Provide domestic hot water 60°C to all

Correct answer: (A)

Meet zone sensible + fraction of reheat/ humidity needs without overcooling, subject to min-flow & SAT limits

Explanation

VAV reheat+SAT reset: avoid cold-deck/zone mismatch.
