RE: [EnergyPlus_Support] Detailed ICE storage - for PCMs? Nodes &





The DesignDay data is used for autosizing HVAC equipment.  The 1% and 2% data will reduce of the equpment size.  The calculation is on the building geometry and may have different result by choosing different simulatin algorithm and site shading. 

You can use all of them, but it will only make the run time longer, and the data more difficult to analysis.

 

The sz.csv simply picks the maximum and minimum values of the columns.  The size of the spred sheet will a lot onter.

 

The designDay sizing is to let you get started with minimum input weather data. It is fast and convenient for IDF debugging.  Simply comparing the ODT and the Zone MAT, you will get a very good idea whether the HVAC is purforming as expected.  If you have any error, it is very fast to get another simulation result after making the correction.

 

Autosizing is not usually the real equipment size, therefore, it is not need to be exact.  The choice of the DesignDay object is not dependent on the building or HVAC used.  0.4% WBW Summer, 99.6% Winter. Please also note that the skyclearance is set to 0.0 for Winter by default.  So you will not get any solar beam values through windows.

 


Regarding the JEPlus, I have the program, and had tried it a few year back.  I do not use parametric run, as the setting up the different parameter is not easy.

 

Optimization on a few parameters using weather file and a few geometry is not very meaning full.

 

Window size to wall size, etc are not normally designed using any lighting criteria.  The occupant usage of the room area is more relavent, in the building design.


If you have a smart interface, what you input in the .rvi and .mvi files can be modified by the program.  So jEplus and EPlus may work differently.

Thank you Dr. Yi, I will save this and use it for future runs. Question
for you, would using all cause any harm? Should I base my choice for
two design days on weather analysis using climate consultant, D-view or
compatible, or would the choice of design days be more dependant upon
the buildings HVAC type, or would the choice be more of a personal
preference or energy code rule decision?

Again many thanks for your shared wisdom.

Nodes & curves question

For para (2) The reason why there are so many DesignDay object example
in the .ddy is that the moisture in the atmosphere is expressed, in
wet-bulb, relative humidity %,humidity ratio, entropy. There are only
three statistical classes, namely, 0.4%, 1% and 2%.

I always use the 0.4% (99.6%) with WBM wet-bulb at maximum dry-bulb
temperature. The four dates for the four seasons are the longest,
shortest, and the equinox. Skyclearance i 1.0 for Winter when doing
zone window beam studies. Jan 17 for Winter designday was chosen,
because ODT average is not the lowest on the shortest day of the year.
The extreme day is usually in August for Summer. The use of TMY was
to remove the extreme cases. Extreme weather week is different for
different locatons and do not have known characteristics. In fact, I
did most of the verification of IDF with no weather files. ASHRAE
prepare the IWEC and .ddy make use of the information and statistical
data from there. With the new DesignDay object format and the WBM, I
can use a swinging thermometer pair to get the two dry and wet values
easily at any time. Dr. Li

Nodes & curves question

Dr. Li
I realized that GJ is Gigi joules shortly after the post when I
switched to IP units and noticed the conversion to ton/hr- I was
thrown off initially by the capacity concept, as I was looking for a
tank size for gallons of water/ice, but have not found any reference
to such a tank. I am now guessing that the GJ/Tonhr is the tank
capacity- and that water must have a specific J/Btu of storage
capacity. The Pure PCM materiel I am experimenting with is rated in
Btu per pound, so I think could just specify the amount of Btu/J
capacity of the PCM for this item. (If I where using water/Ice I
suppose I would have to find the thermal capacity for the total tank
amount but not sure)

I have heard mixed messages about design day objects- for instance I
have been told that all design day objects should be ran to produce
accurate sizing by Linda & Drew, but told by Paulo the same as you say
of only two needed. For using two I wonder what is the best way to
choose the correct design days, and for some time thought it made more
since to use Weather file:extreme summer week/Weather file:extreme
winter week so that I could run the same building at many locations
during parametric runs and so I did not have to make arbitrary choices
of Design Days. Lately I have just been running files with all Design
Days to be on the safe side. I guess ASHRAE standards would be a good
place for me to research for the best day type to choose/use. (your
advise on this was appreciated)

Research Goal: I want to model the thermal energy storage functions
of Pure PCM's, the current PCM modeling capabilities of e+ seem to be
geared towards PCM's impregnated within other materials, and I want to
check the difference in using them as a energy storage vessel, as well
as test if it would be possible to use them in both ways
simultaneously. I have seen empirical data showing benefits that
exceed the benefits modeled with the current finite difference
approach, so am experimenting to see if I can use the ice storage
detailed object to more accurately depict the full benefits of pure
phase change materials. The materials I am doing experimentation with
can be viewed here:
https://docs.google.com/spreadsheet/ccc?key=0Ag7cD5ZV9QwRdHlCSWVfWWV2WG5rQjdaN0dLTGlab2c

I need to read the IO, as I guess I do not understand the Branch
objects very well (I am spoiled in my use of design builder or HVAC
templates so have not created a HVAC system line by line, nor have I
edited branch objects before but now am dedicated to learn how this
works) Are you saying that the placement of the object in the branch
needs to be in a specific order position? I thought order position was
not important and that the node connections where all that mattered.

I read the IO on ice storage and it seems that the chiller is used to
charge ICE STORAGE, but I am looking to use a material with a melt
temp in the 20-30C range so would want to charge the PCM/ICE with zone
or possibly outdoor air, and am not sure if this is possible.

I did not think of the refrigerated room experiment, and will have to
research this in the IO and give it a try.

Part of the reason I am interested in this object is the difference in
real world results/my hand calculations of PCM thermal energy storage
potential and Energy Plus modeled results. My hand calc can be
viewed/experimented with
here:https://docs.google.com/spreadsheet/ccc?key=0Ag7cD5ZV9QwRdFJ1X0JpT1hOcEVMTk5fSlJDZXU4SHc

Thank you much for your response- I did not think anyone was goung to
respond to this thread-

Kind regards-

I have tried running your IDF, but do not know what you are trying to do.

GJ is GigaJoules.

I do not know why you have so many designDay objects. Only two are
needed for sizing. Four, if you are trying the four season solar beam
study, and/or the transistion operation of the HVAC system..

Where do you intend to insert the storage tank? The pipe object
itself is not in the correct order postion of the IDF, therefore the
branch was not recognized and flagged as a severe error.

If you want to discharge the tank load in a zone, then it should be
declared as a zone equipment, or a tank placed in a zone.

I do not know how you can charge an ICE STORAGE TANK. Is it a new
object available in EPlus? This is the first time I come across the
ThermalStorage:Ice:Detailed. I shall try to look it up in the ref.
manuals.

You should use a refrigerated room and control its temperature for the
experiment. The PCM may be installed as the walls of the centrol zone
with the four other peripheral zones as in the 5-zone building as
controlled zones.

Without the ice strage branch, the IDF run was sucessfull.

Hello- I am attempting to experiment with the detailed Ice
storage object, as I noticed it has "freezing temperature of storage
medium" rather than assuming freezing temp for water of 0C/32F. I
added the objects from the example file to to a model I have been
working on and attempted to connect the nodes, but when trying to run
E+ crashes. Also I was thinking to use data from DSC tests of PCM for
the charge and discharge curves, but am not sure how to approach it.
(I am guessing 1=solid and 0= melt, but am unsure), also I wanted to
use the thickness of PCM for the volume of the storage tank, but am
unsure about the GJ, what unit would this be? Any advise would be
great, and thanks in advance-
