<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 />

• Modularity: since INSEL is a programming language, it is entirely modular. It is<br />

possible to define any energetic systems.<br />

• Time steps increment: any time steps can be defined from less than 1sec to several<br />

years.<br />

• Components library extension: It is possible to write source code in Fortran <strong>and</strong> C++<br />

<strong>and</strong> to cre<strong>at</strong>e new components in order to extend the components library by linking<br />

the code to a dynamic link library DLL.<br />

• Meteorological d<strong>at</strong>abases used: INSEL d<strong>at</strong>abase (2000 loc<strong>at</strong>ions worldwide),<br />

European solar radi<strong>at</strong>ion Atlas, Meteonorm, S@tel light plus any other source<br />

available.<br />

Components library<br />

The main components of INSEL rel<strong>at</strong>ed to solar thermal applic<strong>at</strong>ion <strong>and</strong> solar cooling in<br />

particular are:<br />

• Collectors: dynamic models of air <strong>and</strong> liquids collectors<br />

• Storage tanks: fully mixed <strong>and</strong> str<strong>at</strong>ified models<br />

• He<strong>at</strong> exchangers: simple models (parallel, counter <strong>and</strong> cross flows), cross flow he<strong>at</strong><br />

exchanger with condensing <strong>and</strong> icing, earth he<strong>at</strong> exchanger (under development).<br />

• Desiccant wheel<br />

• Absorption chillers: models for Phönix (10 kW) <strong>and</strong> EAW (from 15 to 200 kW) chillers.<br />

• Adsorption chillers: dynamic model under development.<br />

• <strong>Cooling</strong> towers: open-wet model<br />

A specific applic<strong>at</strong>ion for solar cooling: INSEL Cool<br />

An applic<strong>at</strong>ion for solar cooling (INSEL Cool) has been implemented into INSEL in order to<br />

help planners during the pre-design phase of a solar cooling plant. Users have the possibility<br />

to perform simul<strong>at</strong>ion of solar cooling installing by selecting in a list the main components of<br />

the install<strong>at</strong>ion (cooling machines, solar collectors, cooling towers, storage tanks, he<strong>at</strong><br />

exchangers), the loc<strong>at</strong>ion of the install<strong>at</strong>ion <strong>and</strong> the cooling load profile. It is also possible to<br />

define new components <strong>and</strong> new loc<strong>at</strong>ions by introducing himself the required parameters<br />

<strong>and</strong> external cooling load files can be used for simul<strong>at</strong>ion. The analysis of the results can be<br />

done (either with hourly or monthly values) directly from the applic<strong>at</strong>ion as can be seen in the<br />

figure below.<br />
