[bldg-sim] Modelling Pool Areas with eQuest & DOE

[Jeff Haberl]

Hello:

This is tricky...since DOE-2.1e does not really model moisture
conditions, so you can't tell about surface conditions. Also, popular
systems such as the "Pool Pack" HP system cannot be modeled in DOE-2.1e,
and perhaps DOE-2.2. 

However, you can model the coil loads, etc. You'll find some advice in
the paper: Haberl, J., Claridge, D. 1985. "Retrofit Energy Studies of a
Recreation Center",  ASHRAE Transactions-Research, Volume 91, Part 2,
pp.  1421 - 1433, (June), and the technical report on which it was
based. In this work we mimicked the pool load by creating a proxy zone
inside the zone that had all the humidity loads that we estimated with
measured data from the pool at the Rec Center we studied. 

There is also useful information in the FCHART software, including a
list of references that are old but useful, and probably others I'm not
aware of.

Subject: [bldg-sim] Modelling Pool Areas with eQuest & DOE

I am currently modelling buildings with eQuest to simulate proposed 
mechanical retrofits for a Canadian University (to calculate the energy 
savings). My problem is that two of the buildings contain indoor pools. 
The pool retrofits include controls changes to the pool's heating 
converters (steam to hot water), and the pool's circulation pumps. So, I

need to find a relatively accurate way of modeling a pool zone in eQuest

and attaching this equiptment to it.

Does anyone have a good strategy for modeling pool zones in eQuest (or 
simply DOE2)? I need to model:
 - the HVAC system serving the pool area
 - the pool pumps
 - the pool heating converters

To get an idea, the problem is that the temperature of the water 
moderates the air temperature of the zone. This affects the load on the 
HVAC system. In addition, humidity becomes a major factor.

Any discussion on this topic would be great!

Thanks,

Grant Unsworth
