Munters Unit

Has anyone modeled (or approximated) a munters unit in eQuest? Any
suggestions on how this could be done?

Thanks,

Karen-

I have never done this before but I would imagine you could use the "add-on
desiccant" tab on your ERV or DOA unit to create a desiccant that would
regenerate from the cooling waste heat from your chiller. I'm pretty sure
this can be done correctly. Let me know if you have any success.

Karen,

If your trying to approximate the energy use of a Dry Cool Munters Unit
versus a regular unit, in a parametric run, first specify 100% for
maximum humidity control.

You must then adjust your cooling capacity. Remember that a Munters Unit
doesn't need to "over-cool". You could approximate this using a
psychometric chart. Figure out the difference in enthalpy between your
mixed air condition and your coil discharge condition (accounting for
over-cooling) for a regular unit. Then figure out the enthalpy
difference for your Munters unit, which would be your mixed air
condition and your desired supply air condition (55F, 50%RH for
example). The ratio between those differences should give you a good
approximation on how much to de-rate your cooling capacity.
