Information
Test Case 12 of the VDI 6007 Part 1: Calculation of indoor air temperature excited by a radiative and convective heat source for room version S. It is based of Test Case 5 and adds ventilation.
Boundary conditions
- daily profile for outdoor air temperature in hourly steps
- no solar or short-wave radiation on the exterior wall
- daily profile for solar radiation through the windows in hourly steps
- sunblind closes at >100 W/m2
- no long-wave radiation exchange between exterior wall, windows and ambient environment
- daily profile for ventilation in hourly time steps
This test validates infiltration and ventilation.
