[Equest-users] ERV Effectiveness

[Jeremy McClanathan]

I would check the OSA and Exhaust airflow rates through the heat exchanger.  Maybe set them manually.  I have found that eQuest does not always size them how I thought they would be sized.

Subject: [Equest-users] ERV Effectiveness

Hello All,

I set my sensible and latent effectiveness for my ERV at 50% each, but when I trend those points, the maximum value is only about 7%? Any ideas what might be causing that? When I restore default (I think 74%/76%), I get a maximum effectiveness of around 28%. Other inputs shown below. (The schedule is set to only allow the ERV when the unit is in 100% OA mode.)

Thank you,
Joe
