Modeling Ceiling fan or circulation fan in Designbuilder or EnergyPlus

edit

Hello,

I am a student doing research on Mixed-mode ventilation (including fan-assisted ventilation). Which tools I am using are DesignBuilder and EnergyPlus.

So, What I make as mixed-mode ventilation is divided into three types of ventilation: 1) Natural ventilation using single-sided window 2) Forced natural ventilation assisted by ceiling fan/circulation fan. 3) Air Handling unit operation and window opening.

There is much research on mixed-mode ventilation related to hybrid ventilation (fan-assisted). But, the authors didn't provide information about ceiling fan (or circulation fan).

The followings are what I am asking:

1) In a single thermal zone, Is it possible to install the fan without dividing room air? What I mean is some people divide a single room into a thin air space with a large hole and the main room. But I don't want to use these kind of modeling methods.

2) Is there any other example of EnergyPlus or Designbuilder about modeling ceiling fan or circulation fan? I found the youtube video that has contents to model ceiling fan in EnergyPlus. But it did only address making Zone:equipment object which does not influence indoor air pressure or velocity.

3) Using a circulation fan can rise the pressure in a single room?

Please help me. Also, If there is a file example and you don't mind sharing, please share the link
