IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report A-D3b, Date: December 2010
2 General Description of Monitored Systems
2.1 Austria: SOLution Headquaters, Sattledt
Description of the application
Type of building office building
Location Sattledt, Austria
In operation since 2005
System operated by SOLution Solartechnik
GmbH
Air-conditioned area 150 m 2
System used for space heating? Yes
System used for DHW preparation? No
General description of the system
The solar thermally driven absorption cooling system is designed to control the air
temperature of the SOLution Solartechnik GmbH headquarter office (150 m² useful area) in
summer and winter. The system configuration allows a solar-autonomous cooling operation,
e.g. the driving heat for the absorption chiller is only generated and provided by the solar
system. A gas driven boiler allows test routines and as well a significant heating support in
winter.
Since 2008 the company of SOLution Solartechnik GmbH has moved to a new headquarter
building. Therefore the solar absorption cooling system has been disassembled and the
system is not anymore in operation.
