There are evaporator models for TRNSYS that will be much more appropriate. Are you trying to model the entire refrigerant circuit or is your focus simply the cooling of the air?</div><div><br></div><div>Jeff<br><br><div id="AppleMailSignature">Sent from my iPhone</div><div><br>On Mar 1, 2018, at 6:35 AM, Amirreza Heidary <<a href="mailto:amirrezaheidarysbu@gmail.com">amirrezaheidarysbu@gmail.com</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr">
