<strong>IEA</strong> SHC Task 38 <strong>Solar</strong> Air Conditioning <strong>and</strong> Refriger<strong>at</strong>ion Subtask C2-A, November 9, 2009<br />

One of the pre-defined system configur<strong>at</strong>ions is selected <strong>and</strong> the input box for the solar thermal<br />

collector description is opened.<br />

Example of simul<strong>at</strong>ion results: For a defined system configur<strong>at</strong>ion <strong>and</strong> load d<strong>at</strong>a file, the savings in<br />

primary energy consumption (compared to a reference system calcul<strong>at</strong>ion) <strong>and</strong> specific cost per saved<br />

kWh of primary energy are displayed as a function of the system size (storage volume is shown <strong>at</strong> the<br />

x.-axis, the collector area is represented by the different curves)<br />

EasyCool is used internally by Fraunhofer ISE <strong>and</strong> currently not dissemin<strong>at</strong>ed for public use.<br />
