[Equest-users] OA Intake on Energy Use

[Victor Yeung]

Hello modelling gurus,

 

I am modelling a restaurant space located in Canada serve by PSZ rooftop
units.  I notice something weird when I increase the OA intake for the
space.  Space heating energy use goes up as expected, but cooling energy
use went down a tad bit.  This doesn't make sense as I'm bringing in
more hot/humid OA to the space.  I've already setup dual enthalpy
economizers for the PSZ units, so I don't think it's a problem with free
cooling.

 

Anyone can point out what's going on?

 

Regards,
