Dear Nomikos,<br /><br />First of all, if you have an older version of the TESS Libraries, it is not very expensive to upgrade. I would recommend doing that and obtaining the Type1231 radiator. If I did not have that option, I do not think I would pursue active layers. Rather, I would probably just using a pipe and specify the the loss coefficient, then couple that with Type56 via a GAIN input. The validity is questionable, but it might get you close.<br /><br />Regards,<br /><br />Matt Duffy<br /> <br /> <br /> <!--replyfwdwrap--><div style="background-image: url("http://webmail.fusemail.com/de/r_bg_img.gif"); background-position: center top; background-repeat: repeat-x;"><strong>----- Original Message -----</strong><br /><strong>From:</strong> "NOM KARAS" <nomkaras@gmail.com> <br /><strong>Sent:</strong> Thu, October 27, 2011 5:47<br /><strong>Subject:</strong> [TRNSYS-users] radiator_modelling<br /><br /><table cellspacing="5" width="100%"><tbody!
><tr><td><div class="PrivateMsgDiv"><!-- begin sanitized html --> Dear Trnsys users,<br /><br />I want to modell a classic heating system with radiators (that use hot water, heated from a central boiler). I have read previous threads that talk about a component of transsolar (type 362 ) that simulates such a radiator and found that TESS has a similar component type-1231. Unfortunately I don't have these components (I have an older version of TESS library) and I wondered if i could simulate somehow the radiator with type-56 (trnbuild) by using an active layer. I know that active layers are traditionally used for internal floor heating, but I made this consideration :<br /> <br />To add to my heating zone an external wall <u>with active layer</u> and <u>adiabatic conditions</u> on the surface looking to the enviroment ( active layers cant unfortunately be used in internal walls) that has wall area equal to the desired radiator (and by equal i mean the total !
surface of the radiator that takes part in the radiation-convection&nb
sp; heat exchange).<br /> <br />I would appreciate your opinion on this,<br /><br />with regards Nomikos.<br /> <!-- end sanitized html --> <hr size="1" noshade="noshade" /><pre>
