Re: [EnergyPlus_Support] ZoneHVAC:EnergyRecoveryVentilator does not work.

Suggest looking at the .EIO file to review the autosized airflow rate results

Suggest looking at example file = HVACStandAloneERV_Economizer.idf

Hello.

 

I want to model the EnergyRecoveryVentilator(ERV) system in my model.

 

I read the I/O reference, and set availability schedules to always 1 from schedule:compact, but ERV system doesn’t work during the whole year.

 

HeatExchanger:AirToAir:SensibleAndLatent object has same schedule that indicates 1 during the whole year.

 

Every air flow rates are set to autosize, including Fan:OnOff object. Fan object has same availability schedule, of course.

 

In spite of all of these settings, ERV in my model doesn’t work, and doesn’t consume any electric energy too.

 

I can’t see any specific warnings or severe errors in connection with ZoneHVAC:ERV or HeatExchanger.

 

Is there another criteria of operation of ERV system?(e.g. setpoint, operation scheme, and so on..)

 

Any replies will be appreciated.

 

Best regards.

Swj.
