2021-08-05 13:21:49 -0500 marked best answer Modeling plenum and handling floor thickness

This isn't the first thread on plenums, but I haven't found a straight answer on this particular point.

Let's say I have a floor to plenum height of 14', then some ceiling tiles (about an inch, that I'm willing to neglect), then a 3' plenum void, then a 1' concrete slab. The floor to floor height is then 18', but considering the fact that the slab is 1', I don't necessarily want to just assume the plenum void is 4' as I would overestimate the volume by a third.

How am I supposed to enter that in EnergyPlus / OpenStudio to respect both the volumes as well as the exterior wall area (and elevations)?

2021-08-03 22:41:18 -0500 marked best answer Cooling Tower Variable Speed - Which empirical model to choose?

I'm using a CoolingTower:VariableSpeedthat supplies water to my chiller. You can choose mostly between two empirical models:

  • YorkCalc
  • CoolTools (crossflow).

I'm interested in knowing which one I should pick.

I have noted a couple of factual differences. First, YorkCalc uses 27 coefficients while CoolTools uses 35, but that's not a very useful piece of information to have.

More interestingly, the model boundaries differ quite significantly, YorkCalc accepts a broader range of conditions.

From the Engineering Reference, Tower Heat Rejection, Table 64:

Model Boundaries for CT

For the record, YorkCalc is the default in E+.

Does this mean YorkCalc is valid for a broader range of conditions, and would be better?

Do you have any guidance as why I should choose one or the other?
