[TRNSYS-users] Cooling load input

[Jeff Thornton]

While the description below is certainly an option, the loads that
you are imposing on your Type 56 building with this method will be added
to any loads calculated by the building itself. In other words, you will
not get back out the loads that you have pre-calculated with this
approach. A simpler way to do this is to simply "add" the loads to a
flow stream (air or water) and calculate the resultant increase in
temperature, humidity, enthalpy etc. of that flow stream and then
condition the flow stream with heating and/or cooling devices. This can
be done using "Equations" in TRNSYS or, if you have the TESS Loads
Library, there are several components in there that were written for
EXACTLY your situation and make the process a whole lot easier.

into TRNSYS. To do this, in TRNBuild, you can create an input from the
navigator window. Then in the Gain type manager, you can add a gain type
and set the power to the negative of your input data (see manual for
further details). Finally, you assign the gain type to the zones of
choice in your building, and connect your type 9 data reader to your
type 56.

this. I have measured hourly cooling load data (8760 hrs) from existing
building (via Building Automation System) and planning to use that data
in TRNSYS as a building cooling load input. How is it possible to do
that in TRNSYS?.
