Re: [EnergyPlus_Support] air cooler and ceiling fan

["Julien Marrec julien.marrec@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

This type of ceiling fan doesn't bring outside air. It will have three effects in real life:

* Internal gains from the motor: In e+ you can add an electricequipment for that

* Increase air velocity leading to better PMV/PDD: you may increase air velocity by creating your own Air Velocity Schedule in the IDF file if you care about comfort

* De-stratify the air: by default E+ assumes a "fully mixed" room model, meaning the temperature is the same throughout the zone, so that won't be captured unless you want to use a more complex room model. I don't advise doing that since you seem to be a beginner.

Yep, there's also a ZoneHVAC component: ZoneHVAC:EvaporativeCoolerUnit and 5 air loop ones:

• EvaporativeCooler:Direct:CelDekPad
• EvaporativeCooler:Direct:ResearchSpecial
• EvaporativeCooler:Indirect:CelDekPad
• EvaporativeCooler:Indirect:ResearchSpecial
• EvaporativeCooler:Indirect:WetCoil

Hi,

That's called an evaporative (or adiabatic) cooler. I can't recall if there's also a zonehvac component that does that but there's definitely a few that are air loop components (research special and cellpak). Look in the I/O reference guide for "evaporative"

Hi all,,,,

I hope somebody can help me with my questions, I use specific air cooler and ceiling fans for ventilation and cooling but  I couldn't find any information about these equipment in E+... I attached  a photo for this air cooler perhaps it could be  helpful to know if its specifications exist in E+ or not ???? I would appreciate any help

thanks in advance
