Re: [TRNSYS-users] Type 757 Indirect evaporative cooler



Roberto,

  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"

kind regards

Dear TRNSYS users,

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?

I would appreciate any advice.

Regards,
Roberto
