I am using the OS 2.7. There is DX with humidity control, but there is no where that we can select the dehumidification

Is there any solution for this issue?

For a 4pipe FCU, if we are using variable fan variable flow, are the low speed and medium speed inputs being ignored?

If I want to have a variable speed fan that goes down to 50% low speed, what should be the inputs?

We only have Humidifier:Steam:Electric and we have the Steam:gas under E+, What is the best workaround for adiabatic humidifier??

And I am also wondering what is the difficulty that adiabatic humidifiers have never added to E+, from what I see it's only a psychometric solver that already exists within the Energyplus??

That's right, I need to model the fan coils normally. Many Thanks for the guidance

Yes, I did. I'm using OS 2.6, So basically the difference in modeling between having the DOAS ducted to the fan coil, or

Hi

I defined the outside face convection coefficient as an output. I see in some hours during the simulation, this coefficient is 1000 !!! How is that possible? And also in general , which method is more accurate? Because I changed the SurfaceConvectionAlgorithm:Outside from DOE-2 to AdaptiveConvectionAlgorithm and saw a significant difference in one of my outputs.

I am going perform an energy simulation for a warehouse with the height of around 14 m. Since there will be stratification , I was thinking to divide it to two zone, with an air wall at around 3m height. ( which is horizontall). since I also have skylights and dimming control, I am wondering if the air wall is a good option or not?

I am asking because I got this severe error.
* Severe * HeatBalanceManager: SearchWindow5DataFile: Could not locate Window5 Data File, expecting it as file name=..\datasets\Window5DataFile.dat * ~~~ * Certain run environments require a full path to be included with the file name in the input field. * ~~~ * Try again with putting full path and file name in the field.

Many Thanks, should I change input_path in the RunEPlus.bat in this case? by default in the bat file input_path is set to ExampleFiles. Do I need to change something else also?

I have always used EP-launch for running my simulations, no I need to run it from command prompt in windows. So I read the auxiliary programs pdf which says: ".... In the same directory EnergyPlus expects in.idf, the input data file; Energy+.idd, the data dictionary file; in.epw, the weather file (needed only if there is a RunPeriod in the input); and optionally Energy+.ini, the initialization file."

But I have only Energy+.idd file in C:\Energyplus 8-4-0 directory. where should I find in.idf , in.epw and Energy+.ini?

Thanks
