<p>Roberto,</p>
<p> Those parameter values must correspond with the number of
values that are in the data file that is referenced in the
External Files tab. It can be a little tricky to add values to
those files because of their syntax and because you need to be
careful where you insert the new values. I would recommend that
you open the external files using Excel, insert rows (and data
values) as appropriate then resave the file under a new name as
"tab delimited"</p>
<p>kind regards</p>

<div dir="ltr">Dear TRNSYS users,
<div><br>
</div>
<div>I am doing a project to determine whether using a desiccant
dehumidification wheel in combination with an indirect
evaporative cooler is able to provide cool air for a house in
Kuwait as a possible replacement for conventional air
conditioners. Currently, when I try to change the number of
dry and wet bulb cells from the original number in the
parameters section of the TRNSYS component type 757 and then
run my model, I get an error message stating that the
component was unable to correctly read from the external file
containing the effectiveness as a function of the inlet
temperature. Does anybody know how to fix this problem so that
I can increase the number of dry and wet bulb cells in the
parameters tab of the type 757 indirect evaporative cooler
component?</div>
<div><br>
</div>
<div>I would appreciate any advice.</div>
