[EnergyPlus_Support] Re: Baseboard convective at constant capacity

["augustintardieu" <augustintardieu@xxxxxxxx>]

Dear James,

Thank you for your answer. However, the energy use is not exactly the objectives of my model.

In fact, what I want is to simulate the oscillations of the air temperature of the room because of the electric baseboard heater I have. The one I have is connected to a thermostat which setpoints are 20 and 24°C. So, below 20°C, the heater works at its full capacity (1000 watts) till the air temperature reachs 24°C. Then it stops until the air temperature get lower than 20°C once again.

However, with E+, I don't manage to simulate those oscillations because the heater operates proportionally.

Do you know how I could do this?

Thank you very much for your hekp!

Augustin
