Modeling Munters OA Units

All,

Has anyone modeled a Munters dedicated outside air unit in Trace? The type of unit I am trying to model is 100% OA with 100% outside air for regeneration air. So the outside air comes in, passes through a pre coiling coil, then the main coiling coil and then through a desiccant wheel. The regeneration air comes in, passes through a condenser coil to heat up and then through the desiccant wheel to remove the moisture out of the wheel and then exhausted to the outside. I have some ideas of how to do it, but just want to see if anyone has experience doing it. I appreciate any help I can get.

Regards,

Jason Boehning, EIT

I am experiencing difficulty modeling a similar unit. From what I have seen Trace only allows solid desiccant wheels to be placed before the cooling coil. I am not sure how to get around this, so any ideas would help me out as well.

 

Thanks.

If you both could post simple diagrams of what you are doing, I think I could get you an answer.

Here is a diagram of the unit I was attempting to model. We spoke to a rep today who told us he hasn't talked to anyone who has been able to make this work, so if you can help that would be great

I changed the author on that to Jason (that's who I think said it) That way you will get an email with this reply.

This is difficult to model - actually, impossible for most users. It is a considerable amount of modeling work because we have to tie it into heat recovery too.

We also might need to fix a humidity ratio leaving the first stage of the dessicant wheel (Supply air).

You should ask your rep to put us in touch to get Munters to sponsor a segment on this, as I can't see explaining it without a video.
