[TRNSYS-users] Type 107 Absorption Chilller

Wed Apr 9 08:33:21 PDT 2014

Hi Travis,

I worked the last year in a TRNSYS project using a YAZAKI WFC SC 50 with
the Type 107. I got the data to generate the external files from Yazaki
Energy Team. If you need, I have a spreadsheet where you can find the data
by modifying the temperatures and flow rates for different Yazaki water
fired absorption chillers. It is a little time consuming but it is the only
way that I found the last year.

Best regards,

Carlos Naranjo-Mendoza
