IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report A-D3b, Date: December 2010
2.8 France: INES Research Center Offices, Chambéry
Description of the application
The targeted building welcoming the solar cooling application is the PUMA3’s INES research
office. The INES (National Institute of Solar Energy) was created in 2006 by the public
institutions to promote and develop solar technologies in France. To reach these objectives,
the INES is divided into two centers: research, development and innovation on the one hand,
and training and education on the other hand. The INES is located in the “Savoie Technolac”
area which is very close to Chambéry in Rhônes-Alpes area (close to the French Alps and
Lyon). The PUMA3 building is large, but only 3 mezzanine offices are cooled down by the
solar system. The building was created recently so it has a good level of energy efficiency.
Type of building Office building
Location Chambéry, France
In operation since April 2009
System operated by INES
Air-conditioned area 21m²
System used for space heating? Yes
System used for DHW preparation? Yes
General description of the system
The system is based on an absorption chiller of 4.5 kW coupled with 30 m² flat plate
collectors. The installation cools the building in summer, heats it in winter, and it is also able
to produce a small amount of domestic hot water all year long. The 400 liters heat storage
tank is included in a packaged device supplied by Clipsol (SSC BlocSol RSD 120). Included
in this device there is also an electric backup and all the security devices related to the heat
storage. Another tank is installed in the system which is ensuring the cold storage in summer
and a second heat storage in winter. The heat rejection is carried out by a horizontal
geothermal field.
