FW: geothermal and cooling tower WSHP

Karen,

I suspect the problem is with how the geothermal loop is being sized. Is
the loop size based on the heating load?

Sincerely,

I have been trying (unsuccessfully) to get hold of TMY2 text data (comma delimited for example) for import into XL files. Is there a tool that will perform this conversion?

Thanks (in advance)

Dear Vikram,

You can download from the TRNSYS website at University of
Wisconsin-Madison an Excel macro that reads a TMY2 data file and
converts it into a comma separated data file in Excel.

You might want to try the new TMY3 weather file
s
. They are
already in CSV format and can be opened directly using OpenOffice of Excel.

Does anyone have any information on any ASHRAE 90.1-2004 addenda that addresses G3.1.2.8 Design Air Flow Rates.

The 2004 standard uses a 20?F delta T to size the supply air flows.

I have a lab project where the supply air needs to be 100% OA and 8 AC per hour.

I read here: http://www.i2sl.org/eleclibrary/documents/maor.pdf See page 22 that supposedly there is an Addendum that addresses this issue.

Does anyone know where I can find that? I have looked through all the Addendum on the ASHRAE website and came up empty.

I guess the only other thing I think is a loophole is G3.1.2.5: which states that the baseline and proposed must have the same ventilation rates. This to me reads that if you are required to supply say 100% OA then both case should have it.

Any suggestions?

Thanks!

What is the best way to convert these TMY3 files into .bin files for use
in eQuest or other modeling programs?
