Hi everyone,
Now I'm trying a very simple simulation of a natural temperature by using EnergyPlus (OpenStudio). The model is 64 cubic meter (Width 4mDepth 4mHeight 4m), the boundary condition of only one surface with a window (3m*3m) is "outdoor" and the others are "adiabatic". I don't set any internal load or ventilation, and just do a simulation of natural ventilation.
The result is as attached. I cannot understand why the zone air temperature is so higher than the outdoor temperature in the winter season. Especially in January, the zone air temperature is almost 50℃ (120ºF). I cannot find a failure of my setting of this simulation.
Please give me some advice.
