[TRNSYS-users] New TESS Solar components

[Andrés Montero]

Dear Jeff,

 

I have a few questions about type1288. 

The first one is related to the flow rates. Other components let users to
enter the test flow rate for a specific collector but I was surprised since
this Type doesn’t include this variable.  Why is this? How to select the
best flow rate since the one reported on the test standard report is much
higher than the one the manufacturer recommends? 

The second question is about the correct manner to configure a solar array
of X numbers of collector in series times Y numbers of collector in
parallel. Do I have to use a calculator in order to construct such
configuration or is there another way by using Type1288 only?

The third one is about IAM for diffuse radiation. I tried to set a value of
1.015 (according to a certified report) but Trnsys got stuck and I had to
use Ctrl+Alt+Del in order to end the task. So I used a value of 1 and
calculations were performed without any problem. Do you know the reason for
this problem? 

And the last question. What is the best way to calculate the efficiency of
collectors using the EN-12975 standard? How do I get this value in Trnsys?

 

Thank you!
