HVAC performance curves with dependent variables as function of IP units

[GoogleCodeExporter]

What NACM Section(s) are relevant to this issue?
5.7, 5.8

Explanation of issue:
Many of the coil and primary equipment curves are listed in the ACM as a 
function of temperature... in IP units.  

E+ is SI based, so I see two options:
1) Provide curves to OS translator in IP units and have it convert them to SI 
units.
2) Convert existing ACM curves based on IP to SI units
3) Generate new set of curves from Ref Method idf files

Kyle indicated option 1 is a fair amount of work and not possible in the 
Release 1 timeframe (Kyle please comment if I am wrong on this). Option 3 
doesn't make a lot of sense since it is not clear to me that the Ref Method 
idfs have curves that were developed from the DOE-2 based ACM curves.  

Therefore, I see Option 2 as the near-term solution.  This task needs to be 
done by 5/15 (est.) so review of simulation results based on ACM curves can 
happen ASAP.

360 has resources to assist with this work, but want to make sure this is 
coordinated with work that may have already began.  Also, need to decide if the 
ACM appendix should include both SI and IP curves.

I checked in an updated Appendix 5.7 workbook to the CBECC repo @ r439:
http://code.google.com/p/cbecc/source/browse/trunk/RulesetDev/Rulesets/CEC%20201
3%20Nonres/Rules/Library/Appendix_5.7_Performance_Curves.xlsx

This workbook should be relatively close to 100% complete for Release 1.  I 
have not highlighted all the curves that need to be converted, but we can 
identify those quickly based on the independent variables and E+ curve 
descriptions listed.

Please let me know ASAP if this is something you want 360 to work on.  If so, 
John, please forward on that translator application or spreadsheet you 
mentioned you had already found.  I am available until 6pm this evening if 
you'd like to discuss and checking email this weekend.

Proposed resolution:

Please provide any additional information below.

Changing the status as Discussion, since the IP curves were converted to SI 
units; however, there are some potential issues with the direct-fired 
absorption curves and engine-driven chiller curves that I plan to look into 
after the first release. A couple of these curves appear to be biquadratics, 
but are actually two quadratic curves that are multiplied together.

Reviewed with John. This is low priority and will be addressed later

I believe this is complete. Changing priority status to Medium and status to 
Fixed.

John, this issue is marked as Fixed, but in comment #1 you note "some potential 
issues with the direct-fired absorption curves and engine-driven chiller curves 
that I plan to look into after the first release." 

The items I raised in the original issue have been addressed. Revising status 
until you have a chance to review.  If you review and feel no further action is 
needed, please close the issue (DoneVerified or WontFix)
