Dear all,<div><br></div><div>STILL for CO2 concentration issue, I defined two adults in one zone. One guy produces CO2 20 L per hour, two guys 40 L. The zone volume is 100 m^3. I defined The outdoor CO2 concentration is 400 ppm, there is no cracks in the zone. After 1 hour, indoor CO2 concentration should increase 40/100 000 = 400 ppm. After 1.5 hours, it should increase 60/100 000 = 600 ppm. I.e. at this time indoor CO2 concentration is 400 + 600 ppm = 1000 ppm. </div>
<div><br></div><div>However, there is a WEIRD result: when I set the time step as 1 min, only about 0.8 hour indoor CO2 concentration increases to 1000 ppm. when I set the time step as 3 min (0.05 h), about 1.5 hours it becomes 1000 ppm.</div>
<div><br></div><div>PLEASE relative experts explain it! I should believe which one? So how can TRNSYS/TRNFlow make me believe you? there is still having the former another WEIRD PID controller ISSUE which is still WEIRD from last week until now. There is still no one who can solve that ISSUE.</div>
<div><br></div><div>Many thanks in advance!</div><div><br></div><div>br</div><div><br></div><div>wang</div><div><br></div><div><br><br><div class="gmail_quote">2011/11/24 <span dir="ltr"><<a href="mailto:trnsys-users-request@cae.wisc.edu">trnsys-users-request@cae.wisc.edu</a>></span><br>
