RE: [EnergyPlus_Support] Digest Number 1155
1. The COMIS analysis allows a natural ventilation calculation. The calculation is simpler than a CFD. Basically the zones and openings are networked into a set of equations that can be solved for pressure/flow.
2. I have subdivided floors and walls in EnergyPlus models to look at surface temperatures. Since the heat flow analysis is only 1d (EnergyPlus only calculates heat flow through a surface, not to/from adjacent surfaces through the thickness), a subdivided surface should give you fair approximation if you select a representative size surface. My calculations seemed to work well with beam solar gains. The results will also be distorted because the space air volume is assumed to be evenly heated. I am uncertain about surface temperature calculations using radiant panel heating, it appears that a small panel located in the room will evenly heat all other surfaces in the space, even if they are not directly facing the hot surface.

Subject: RE: [EnergyPlus_Support] Digest Number 1155
Two questions:
1. In Energy Plus, it is possible to have two zones stacked (two floors)
with openings/vents between them. Since Energy Plus doesn't do CFD, how is
the air exchange handled between zones?
2. Is it possible to divide a single slab into a mesh to measure the
temperature gradient across a slab? (e.g. due to uneven solar radiation on
the slab)
Thanks,
Troy

Hi,
I guess this question is for the users who used DOE2
as well. What would be the equivalent report variables
in E+ for SS-D (HVAC Loads - system size) and BEPS
(Electricity and Gas consumption) reports of DOE2?

Subject: Re: DOE2 equivalent of reports
For EnergyPlus, you need to request a 'ABUPS' report
to get the equivalent of BEPS. The equipment sizing is
in the .EIO file (ie <yourinputfilename>.EIO). The .EIO
including zone, system, airflow, fan, and equipment sizing,
showing which design day was used.

Subject: Re: Daylighting detailed
It sounds like a geometry problem. Are you using Relative or World
Coordinates? It sounds like some surfaces may be facing opposite of what
they
should be. Use "Report, Surfaces, Details;" to generate a list of all
surfaces
and subsurfaces which includes tilt and azimuth. This report is placed in
the
eio output file. Opening the file in Excel (using comma delimiters) makes
it
most easy to read. Check that all surfaces are facing in the desired
direction.
Note that the coordinates for daylighting reference points are all relative
to
the zone origin (regardless of the choice of relative or world coordinates
for
surfacess).

specify a different Construction name.
2. Yes, see "CONSTRUCTION FROM WINDOW5 DATA FILE"

Subject: RE: Re: Solar Array with Boiler for DHW
Hello Elmer,
The WATER HEATER:STRATIFIED object does not exist yet. Sorry about the
mistake in the documentation. A similar way to "realize energy savings" can
be accomplished by using two WATER HEATER:MIXED objects where one serves as
the storage tank coupled to the solar collectors and the other acts as an
auxiliary heater to make up the remaining temperature difference if the
storage tank water is not hot enough. I think this is probably what you
want to do.
To make the WATER HEATER:MIXED function as a storage tank, i.e., do
nothing/no heating, simply set the heater capacity to zero.

Subject: [EnergyPlus_Support] Re: Solar Array with Boiler for DHW
I'm going to try and send this again as the 'Rish Text Editor (Beta)
made a mess of my last attempt...
I've been looking at that example...
On page 821 of the input/output reference document it says...
"In order to realize energy savings with a solar heating system, it
is necessary to use the
WATER HEATER:STRATIFIED object for thermal storage."
To which water heater is this referring to?
I'm trying to emulate a system that uses 6 solar collectors that
provide heating for DHW (similar to the example you highlighted).
The water is initially heated in a vessel @40oC. When the solar
collector does not provide enough heat to heat the water, extra
heating is provided from a separate boiler circuit which also
provides for other disparate systems. This water is then fed into
another water heater which heats the DHW to a final temp of 60oC.
Does anyone have any ideas how I might set up a similar system in
E+.
I would like some advice on how good/bad/awful my proposed is...
Approach (This is only possible if I can make the water heaters do
nothing and impose a control whereby the full load is picked up by
the water heater source. Is that possible?)
Solar Collector -> (temp pickup +) Heat Exchanger #1 -> Water
Heater #1 @40oC
Boiler -> splitter {
(split 1)|-> Heat Exchanger #1
(split 2)|-> Water Heater #2 @ 60oC -> DHW
* I would set the Heat Exchanger #1's efficiency to values
that make it similar to the efficiency of the water heater to boiler
circuit setup. This should emulate a twin source for the water
heater.
Does anyone have any thoughts?
Kind regards

There actually is an "offline" facility that I use for storing all
the messages. (Also, Yahoo's search is not bad but takes a while to
get through all the messages). The offline reader that I use is
called "PG Offline" (http://www.personalgroupware.com/). I just
exported the database and it's 5MB compressed (which I can't upload

Hi Fred,
Thanks for that. I am using a heat exchanger air to air generic
which looks like the following...

AHU1 Exhaust Node, !- Exhaust air outlet node name

Yes, !- Supply air outlet temperature
control
Rotary, !- Heat exchanger type
None; !- Frost control type
As you can see, I set the 'Supply air outlet temperature control' to
YES in order to moderate the intensity of heat exchange between the
two streams. However, I would prefer to give priority to zone
temperature. Is there any way to doing this?
The reason I want to do this is because on the rare occasions in
Ireland when outdoor temp is above 21oC, then the inlet stream temps
will be above my heat recovery outlet temp setpoint. Unfortunately,
this seems to make the heat recovery unit think it should engage in
full heat recover which pushes outlet temperatures well over 50oC
Any help would be greatly appreciated or am I missing something here?
Kind regards
