Engineering question

Supply system and airflow had to be assessed for cold and warm states without separating comfort, transient response and component thermal effects.

Model & approach

  • Define the cabin, glazing, air supply and thermal loads as a coupled model
  • Compare baseline and candidate HVAC concepts under consistent scenarios

Boundary conditions

  • Steady and transient heating or cooling states
  • Convective, conductive and radiative heat transfer within the documented boundary

Results of the assessment

  • The archive evidences the task, preliminary sizing, geometry and comparison logic.
  • No final simulation report or documented system selection was present.

Engineering consequence

The study was intended to support a traceable HVAC and distribution choice; no public performance result is inferred.

Context

The reviewed archive evidences the task and model scope but contains no final result report. No performance or implementation claim is therefore published.
