Engineering question

A new airtight container concept had to remain within a safe temperature range at high ambient temperature using air-conditioning units only.

Model & approach

  • Balance total heat load and cooling capacity
  • Examine air paths in front of and behind the storage modules
  • Compare component positions, flow distributors and alternative cooling architectures

Boundary conditions

  • Thermally demanding ambient condition
  • High solar radiation as an additional boundary condition
  • Airtight container with air-conditioning units

Results of the assessment

  • The published analysis describes the cooling capacity as adequate for the modeled load case.
  • Cool air routed behind the storage modules improved the critical temperature distribution.
  • Additional flow distributors were assessed as unnecessary for this layout.

Engineering consequence

Component position and targeted rear-side airflow were identified as key design levers.

Context

The stated findings come from the completed container case. Other archived cooling-concept assignments are included only for their task and model logic because final reports are absent.
