Hello World!

I would like to simulate a solar cooling system which generates hot power with Concentrated Solar Power (parabolic trough collector) system integrated an Acummulation Tank and an Absorption Chiller. Parabolic Trough Collector system should also track the sun in one-axis. But I cannot find any component in EnergyPlus libraries about neither Concentrated Solar Power Systems nor sun trackers in the EnergyPlus's library.

Is there any way to simulate such systems?

Thanks in advance!!

EnergyPlus does not have a model for a concentrated solar power collecter like a parabolic trough. You might be able to use the flat plate model and approximate the effect by modifying the performance. The SolarCollector:FlatPlate:Water input object could be used with the SolarCollector:Performance:FlatPlate input object. The SolarCollector:Performance:FlatPlate input object has inputs for the efficiency that can be increased as well as angle modifiers. These are documented in the InputOutputReference but most of the details are in the EngineeringReference.

If that does not work, you might be able to add an Energy Management System (EMS) script to approximate the performance.

Thanks Jason. I will add the SolarCollector:Performance:FlatPlate object. What about working schedules of the solar collectors? I would like my solar collector gains energy whenever it is exposed to sunlight. Do I need to add a working schedule?
