[Equest-users] evaporative coolers in equest

[Nick Caton]

Hi Deepika,

 

I'm not certain any increase/decrease in cooling loads (such as solar
loads affected by changing glazing) should have any effect on the
reported "space cooling energy" when you're using evaporative coolers.
Direct evaporative (swamp) coolers of the simplest sort have only fan
and pump energies to consider -  no refrigerant!  I would advise looking
up the Detailed Simulation Reports Summary page 158/160 to review end
use categories and what they cover. 

 

I am unfamiliar with Bridgeport's climate, but as a general rule if I
observed a significant amount of glazing in a space served by a direct
evaporative cooler... I'd be extra cautious to ensure the HVAC designer
is carefully considering condensation and potential for other
humidity-driven issues along the way.  I'm most used to seeing them
applied to well-ventilated and/or open-air spaces such as garages and
gyms/hangars.

Hello all

I am modeling a building in Bridgeport, CA which has evaporative
coolers.

I dont see any benefits if I replace existing clear glass with low-e in
cooling energy consumption.

Did anyone model evaporative coolers/swamp coolers before?

I want to know whether there is a way to show cooling benefit with such
HVAC system.

Thanks

Regards

Deepika
