Re: [EnergyPlus_Support] Packaged VAV system

I am not sure how it will perform as I am yet to simulate. But with the twospeed coil I got a lot of psychrometric errors and that is why I thought of using the singlespeed coil.

Dear Vinay,

 

While possible, I suspect that it may stretch the coilâ??s abilities, especially at low air flow rates.  I seem to get a lot of psychrometric errors with that setup.

Yes it is possible. See example file TermRHDXSystem.idf.

Hello,

 

I am trying to model a Packaged VAV w/ Reheat. Is it not possible to model the system with a SingleSpeed DX Cooling Coil? I did run the model with this setting but it gives me a warning saying - probably incorrect cooling coil model

for the VAV system. Any guidance would be appreciated.

 

Thank you.

 

Regards,

Vinay
