[TRNSYS-users] type 107 or 680 absorption chiller



Absorption Chiller Users,

(this message was sent to some with attachements)

I have not recieved and data from Yazaki. It has
been about 2 or 3 weeks since I asked for it. We should
have asked for it before we paid them.

Either way. I think I have created a few absorption chiller
data files that model the Yazaki SH20. I am getting TRNSYS
to output changes in temperature for hot and chilled water
flows very close to the tempertures changes calcultated by
hand calculations like the examples on the yazaki web site.

Attached are 4 .dat files a TRNSYS project file and an Xcell spread sheet. The 4 .dat files are for 100%, 120%, 65% and 55% of rated flow. The project file is what I used to test the output.

In the spread sheet, the left side of the sheet is where I calculated the fractions and the right side is where I compared hand calculations to TRNSYS results. I was very surprised that they are so close after
I was so confused trying to create the data files.

The data files are for the range of temperatures given in the Yazaki website. To give TRNSYS some data to work with I put data in each .dat file for a chilled water set temperatures of 7 C and 7.1 C. However, the 7.1 C data is simply the 7 C data repeated. I got that
idea from Sebastien.

I did not get to try your new type Sebastien. I do not know what to do with the files you gave me in order to get an instance of the new
type into a project. One day I ll figure it out.


Hope this helps.
