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.
