Information

Test Case 9 of the VDI 6007 Part 1: Calculation of indoor air temperature excited by a radiative and convective heat source for room version S with two exterior walls. It is based on Test Case 8.

Boundary conditions

  • daily profile for outdoor air temperature in hourly steps
  • daily profile for solar radiation on the exterior wall
  • daily profile for solar radiation through the windows in hourly steps
  • sunblind closes at >100 W/m2
  • long-wave radiation exchange between exterior wall, windows and ambient environment

This test validates reaction of indoor air temperature at mixed internal gains and outdoor impacts including solar radiation and long-wave radiation on exterior walls.
