[Equest-users] Active Chilled Beams

Hi Michael,

I had a weird problem like that once and it went away after I returned my HVAC system temps (supply, max and min cooling resets, etc.) to typical values.  eQuest kept crashing but would not print an error anywhere.  I never tracked down the specific problem or range of values that was causing it.  Good luck.

Subject: [Equest-users] Active Chilled Beams

I have been trying to model 4-pipe active chilled beams and am having no success.  I am using Induction Units.  Each time I try to run a simulation, it tells me that it can't complete due to an error, but it does not show me the error (on the output file or the bdl check).  I have tried oa-from-system with a dummy zone, dedicated chw and hw loops for higher chw temps and lower hw temps, and many other configurations.  I have started over about 10 times by now.  I know I am doing something wrong.  If anyone has successfully modeled this system, please help!  I am about to attack my computer!

Thanks,
