VDI 6007 Test Case 7 model
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Test Case 7 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. Is similar with Test Case 6, but with a maximum heating/cooling power.
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 heat load calculation with maximum heating power.
