Dear all,<br><br>I chose the TYPE 23: PID controller, I design the system is that
CONZ1(Mass concentration of CO2% in zoon) as Setpoint of PID controller is 1000ppm*1.98(co2 density)/1.293(air
density)=0.00164 (kg/kg), the Control Signal's Output links to Control OP_Factor(Opening Factor of window),
the real CONT1 (Mass concentration of CO2% in zoon) of Zone as Controlled Variable, but to my Surprise, CO2% still
kept rising, PID cann't work, I try to look for the reason all the
day,but draw a blank. I think it's a bug or other reasons? <span></span>Please check the Attachment.<br><br>Millions of thanks!<br><br>Br.<br><br>wang<br><br><div class="gmail_quote">2010/8/31 <span dir="ltr"><<a href="mailto:trnsys-users-request@cae.wisc.edu" target="_blank">trnsys-users-request@cae.wisc.edu</a>></span><br>

<div bgcolor="#ffffff">
<div>Dear all,</div>
<div> </div>
<div>I am working on simulation of a solar combined borehole thermal storage for
<br>heating and cooling residential buildings using TRNSYS 17. The main Types
<br>used in the model are Type 505b, 557a and 56.When I run the simulation I get
<br>following error.<br><br>TRNSYS Message 427 : An OUTPUT
from the specified component model has <br>been written to the global OUT array
in a location beyond the allocated <br>number of outputs from this model. Please
check the component carefully to <br>insure that INFO(6) is set correctly. The
simulation has been aborted to <br>avoid problems caused by over-writing the
outputs from other component <br>models Reported information : Not
available.<br><br>As suggested in the TRNSYS archive, I looked at the *.lst and
*.log files. <br>The error is generated by the Type 505. This error is very
frequent and most <br>of the time I am able to debug by trial and error. But
this time, I am not <br>able to do it. I suspect with the array size. Does any
one have know what I <br>need to do. I cannot proceed further in my work
due to this error.<br><br>With best regards,<br>Tshewang

<div>Dear all,</div>
<div> </div>
<div>I will travel to Leeds, UK within the coming 10 days and I will stay there for about 10 days. I Wonder if I get TRNSYS training during my stay period at Leeds. I am ready to travel to cities not far from Leeds for the TRNSYS beginners training course. Kindly, direct me to such training course.</div>

Fred,<br>
perhaps I need to see the project. If you are passing 22.2 dry bulb
and 14 wetbulb to Type33, it should just be spitting back the exact
same thing with a calculation of RH. I just tried that and I'm getting
an RH of 40% at 1atm pressure. When you say there is a 6.8C wetbulb, is
that on the other side of the energy wheel?<br>
