<div>Dear all,</div>
<div> </div>
<div> Happy Chinese New Year!</div>
<div> </div>
<div> I have a question about Boundary Temperature:</div>
<div> </div>
<div>If I defined Boundary walls and their boundary temperature as 10 C, meanwhile, I defined Infiltration rate as 0.5.</div>
<div>Please tell me at this time wheather the infiltration works? Or
what other weather conditions must I define the infiltration will work?</div>
<div> </div>
<div>Because I got the results of QHEAT which are the same when the infiltration is on or off.</div>
<div> </div>
<div>Please give me some advices!</div><br>PLUS:I used QINF, but the results are very strange. The results are the same i.e. 190.73 kJ when turning on or off the INFILTRATION.<br><br><br>many thanks!<br><br>br.<br><br>wang<br>

Subject: Re: [TRNSYS-users] steam producction in a tank with a heater coil inside<br>The answer depends on whether you are producing steam in the tank or just heating water. If you are just heating water then Type 534 from the TESS Libraries will do a great job. If you're intent on producing steam I don't believe there is a steam heater with storage - there are quite a few without storage though...<br>

Date: Sat, 5 Feb 2011 18:40:47 -0600<br>Subject: [TRNSYS-users] unmet cooling load with Type 665.<br>Hi!<br><br>I modeled a 20m*20m*3m building with a 3m high unconditioned attic. I<br>defined the attic as a separate zone and conditioned only the<br>
inhabited space (SPACE1) below. I used type 665 to model an air-source<br>heat pump system and tried to meet the heating and cooling loads of<br>the inhabited space (SPACE1). I am sending the necessary files as<br>attached to this file. Attached folder also contains the window data<br>
file (W4-lib) and the weather file (austintxDOE2EPW) that you will<br>need to run the file. You can run the file and see that, during the<br>summer, the temperature of the inhabited space (SPACE1) exceeds the<br>cooling setpoint temperature while cooling rate stays almost constant.<br>
This made me think that there might be a cooling coil capacity limit<br>somewhere, which I could not figure how to modify/change. I suppose<br>TRNSYS actually autosizes the cooling coil in Type 665. What might be<br>the parameter that is limiting this capacity? ...or is there some<br>
other reason? Could you please help me figure out why I am not able to<br>meet the cooling loads in the attached model?<br><br>Thanks in advance for your time,<br>Best Regards,<br>Simge Andolsun<br><br>_______________________________________________<br>
