Information

Test Case 11 of the VDI 6007 Part 1: Calculation of heat load excited with a given radiative heat source and a setpoint profile for room version S. It is based on Test Case 7, but with a cooling ceiling for cooling purposes instead of a pure convective ideal cooler.

Boundary conditions

  • constant outdoor air temperature 22°C
  • no solar or short-wave radiation on the exterior wall
  • no solar or short-wave radiation through the windows
  • no long-wave radiation exchange between exterior wall, windows and ambient environment

This test validates implementation of cooling ceiling or floor heating.
