Date: Thu, 26 May 2011 16:14:38 -0400<br>Subject: [TRNSYS-users] SDHW template Tin and Useful energy gain- strange behaviour<br>Hi All,<br>
<br>
I played around a little bit with different efficiency equations for the collector, and wanted to compare the results.<br>
Therefore I used the SDHW template (with TYPE1 as collector), which uses the outlet of the Tank as inlet temp to the collector.<br>
I erased this connection and set the inlet temp to a fixed 10 deg but in fact is it still varying when I plot it (from 10-13deg).<br>
How come?<br>
<br>
Another thing that I experienced: when I used the system in the normal mode (Tout tank connected to Tin collector), the useful energy gain of the collector is higher than with a fixed (and in average 10 deg K lower) input temperature.<br>
<br>
Shouldn't it be the opposite?<br>
As Q=m*cp*(Tout-Tin) , the smaller Tin, the higher Quse (assuming that Tout is not that heavily affected)?<br>
<br>
Clarification highly appreciated!!<br>
<br>
Best,<br>
Philip<br>

Date: Fri, 27 May 2011 13:58:10 +0300<br>Subject: [TRNSYS-users] Unable to create new weekly schedule<br>Dear users,<br><br>I have TRNSYS version 16.00.0036 (TRNBuild version 1.0.76). While working in TRNBuild, I was attempting to create a new daily and weekly schedule to use in artificial lighting, since none of the existing schedules were of use to me. However, it is not possible to do such a thing, since in the new schedule window, I am unable to switch between daily and weekly schedule. The relevant radio button is set to "daily" and is greyed out, I can't change the selection. I can create a daily schedule without problem, but it is useless to me since I cannot determine when it is implemented during a week. Anyone else has this problem? Any solutions/suggestions?<br>
<br>Regards,<br><br>Alexandros<br>
