RE: [EnergyPlus_Support] setting item of an idf file





This is easy to do with EMS.  Make the temperature a sensor, make the air exchange an actuator, write a short program to calculate the exchange rate.  I just did this for a simulation I am working on and found that I had to calculate at the end of a time step rather than the beginning.  For some reason a calculation at the beginning of the time step was not implemented for air exchange until the next step anyway.  Now you will also have to consider your time step impact on the simulation.

Subject: [EnergyPlus_Support] setting item of an idf file

 

 

Hi.

I want to increase an air change rate, when outside air temperature is Centigrade 18 and in between Centigrade 27.

I would like to know the setting item of an idf file.
