Re: [EnergyPlus_Support] Thermal Comfort modelling



Hi Hisham,

You air speed is to low. Try with 0.1 m/s. 

What about the temperature heating/cooling? Maybe it's to high or to low?

Dear all,
After trying all variations possible, the FangerPMVs and PPDs show very large deviation from average, for example: for one office space, PMVs vary from around 0 to 4.8 and average is 2.4 around the year (values are measured at times HVAC is running only). This corresponds to:
activity level of 157.5 and
clothing of 1.025 and
air velocity of 0.005,
boilers and chillers are autosized (for other experiments I put real sizes which also returned largely ranging PMVs),
MRT type is ZoneAveraged,
Sensible Heat Fraction is set to autocalculate,
Fraction Radiant is 0.3 and
people density is 25.54 m2/person.

Please advise, how to get these PMVs inside +-0.5 or +-0.7 range for 98% of year.

Thanks in advance.

Hisham.
