[Bldg-sim] Modelling of ceiling fan

[Timothy Moore]

Deepak ,

 

If your focus is indeed thermal comfort, within IES VE you can, if
desired, adjust heat transfer coefficients for surfaces, which will
influence radiant comfort, and in the results viewer adjust the air
velocity for thermal comfort analysis. 

 

If you wish to look at any one simulation time step in more detail, you
can then export the boundary conditions, etc. to the CFD module in the
VE and look at local air velocities and thermal comfort in a space with
the ceiling fan, or at least a reasonable approximation of such a fan. 

 

If you wish to look at the energy saving potential for ceiling fans, you
may first want to study the thermal comfort implications with respect to
room temperature set points (i.e., can you use a higher cooling set
point to achieve the desired level of thermal comfort with the ceiling
fan). Having done so, you can then run the energy model with adjusted
set points to determine energy savings and re-check the thermal comfort
analysis to ensure that the design requirements throughout the simulated
time period will be met with the adjusted set points plus ceiling fans. 

 

Regards,

Timothy

Dear All,

 

Is it possible to model the effect of ceiling fan on thermal comfort

conditions in Energyplus for hot and dry Indian climates.

 

Thanks in advance for any suggestions.
