IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report, Date:… 1 Introduction 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. 2 System design The system is based on an absorption chiller of 4.5 kW coupled with 30 m² flat plate collectors. The installation is cooling the building in summer, heating in winter, and it also producing 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 system is done by a horizontal geothermal field. Installation’s scheme: Building: - Type of building: Office building - Location: Chambery, France - In operation since: April 2009 - System operated by: INES - Air-conditioned area: 21m² - System used for space cooling and heating (DHW production possible but not used)
