Re : Re: [EnergyPlus_Support] question about AirLoopHVAC



Hi Richard,

I come back to you on this topic. I succeeded to connect the exhaust stream and I am now able to run a complete simulation.

My problem now is that I would like to have the same flow rate in both branches: the process branch and the exhaust branch. In the file I sent (please refer to attached file Dunkle_cycle_v1.pdf), this occurs only when the outdoor air fraction is 1 (in the file, when x=1). For any other fractions, the flow rates become unbalanced.

Do you think adding another outdoor air mixer could solve the issue (please refer to the file Dunkle_cycle_v2.pdf)? If no, could you please suggest me a way to solve it?

Many thanks for your help!
Herve

I am fairly sure that will work. At least the code seems to allow it. You will need to attach your input file and send to:

energyplus-support@xxxxxxxx

or submit a ticket through the help desk web site at:

Hello,

I have tried to model the attached AirLoopHVAC system under Energy Plus (see attached file "Dunkle_cycle.pdf ").
I obtained the following error : Invalid Air Loop Component Type = "HEATEXCHANGER:AIRTOAIR:SENSIBLEANDLATENT". Why does Energy Plus have such limitation? Do you know any workaround that I could use?

Thanks in advance for your help.
Hervé
