[TRNSYS-users] Heat load calculations

[amit2065 .]

Dear All,



I am facing problem while calculating the Heat load Calculations with
TRNSYS 17 version.

My quaries are



1). How you define initial zone Temperature and Relative humdiity values.
Is it

always fixed as 20 Degree Centigrade and 50 % RH or their is some logic
/reason

behind it.



2).While doing Heat load calculations How the values for max heat load
calculations

    like

       a). Min ambient Temperatue

       b). Room set Point Temperatue

       c) Temperature of Boundary Values

       d) Air Change rate

is set ?. I understand that the values of Min Ambient Temp is set according
to the weather file/ location

for which the heat load calculation is to be calculated and Room set Point
Temp is according to set

Point tempetaure Cooling . Pls correct  if I am wrong. What about the
Temperature of Boundary

values and Air Chnage rate.How they are selected ?  pls clarify.



3) when I run trnsys for calculations of heat load after setting the points
at (2)  above the message

is displayed "fatal error occured in Trnsys, check listing file for errors.
When I  check the

listing file  again second message is displayed , "not possible to edit log
file as simulation

is running".

I fail to understand the above behaviour, As everything in Trnsys simulation

is fine and it displays the results of other outputs as asked for.
