What is TRNSYS?TRNSYS is simulation software for thermal and
electrical system.FeatureApplicable to solar PV simulation, solar
thermal simulation, HVAC simulation, renewable energy simulation
(wind, solar), and many others.Has a building simulation (TRNBuild)
which can be connected to TRNSYS simulation.Has a built in weather
data library for solar thermal simulation.

CommandAll of the component can be found here which then drag to
the workspaceSolar Collector
Example of TRNSYS Simulation Model Solar Thermal CollectorThe
arrow between each component represent data connection between both
components.The connection list can be set or reviewed by double
clicking the arrow.The figure show the data connection between
weather data and solar connection where some information from
weather data are used as input data for solar connection.

Example of TRNSYS Simulation Model Solar Thermal CollectorBy
clicking each component, information windows as shown in the figure
(For solar collector) can be shown.The Parameter shown fixes
information. For example, for the case of solar collector are
collector area, efficiency, # of collector, etc.The Input shows
transient information such as: inlet temperature, inlet flow rate,
ambient temperature. This information can be set as a constant or
set equal to output of other component as shown in the previous
slide.The output is the output result calculated such as outlet
fluid temperature. This can be an input for the next component.
*A detail information about each of the variables can be shown
by clicking the More bottom next to unit as shown in the figure
above
TRNSYS Tutorial and GuidelineTRNSYS tutorial can be found under
help on the top left toolbox on TRNSYS window.Recommended to try
tutorial section 1.5 and 1.6 in 1. Getting Started for thermal
collector and building block tutorial.More detail guideline
regarding TRNSYS can be found in 2. Using simulation studio More
detail guideline regarding TRNBuild can be found in 5. Multizone

TRNSYS ExampleTRNSYS come with many build in examples which can
be found in: (The location can be vary depend on where TRNSYS was
installed.Several good examples: Begin => Solar thermal
collector example (The same as the one created on the example in
section 1.5 of the guideline). 3D_Building => An example for
building simulation using TRNBuild and TRNSYS. Sun-space shading
=> An example to calculate irradiation due to shading.
