<p>Dear All, </p><p> </p><p>I am facing problem while calculating the Heat load Calculations with TRNSYS 17 version.</p><p>My quaries are</p><p> </p><p>1). How you define initial zone Temperature and Relative humdiity values. Is it </p>
<p>always fixed as 20 Degree Centigrade and 50 % RH or their is some logic /reason </p><p>behind it. </p><p> </p><p>2).While doing Heat load calculations How the values for max heat load calculations </p><p> like</p><p>
a). Min ambient Temperatue</p><p> b). Room set Point Temperatue </p><p> c) Temperature of Boundary Values</p><p> d) Air Change rate </p><p>is set ?. I understand that the values of Min Ambient Temp is set according to the weather file/ location</p>
<p>for which the heat load calculation is to be calculated and Room set Point Temp is according to set </p><p>Point tempetaure Cooling . Pls correct if I am wrong. What about the Temperature of Boundary</p><p>values and Air Chnage rate.How they are selected ? pls clarify. </p>
<p> </p><p>3) when I run trnsys for calculations of heat load after setting the points at (2) above the message </p><p>is displayed "fatal error occured in Trnsys, check listing file for errors. When I check the </p>
<p>listing file again second message is displayed , "not possible to edit log file as simulation</p><p>is running". </p><p>I fail to understand the above behaviour, As everything in Trnsys simulation</p><p>is fine and it displays the results of other outputs as asked for. </p>
