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. Central air-conditioning unit Technology Closed cycle Nominal capacity 4.5 kW cold Type of closed system Absorption Brand of chiller unit ROTARTICA Chilled water application Fan coil Dehumidification No Heat rejection system Geothermal field, exchange area about 138m² Solar thermal Collector type Flat plate collectors Brand of collector CLIPSOL Collector area 30m² Tilt angle, orientation 30°, 10° Collector fluid Water glycol Typical operation temperature 80°C Configuration page 28

Meanwhile, the collector efficiency was about 22%. In summer of this year, the thermal COP of the chiller was very good (high and stable) and was about 0,74 in average for the entire cooling period. Focusing on the performances of one very good and sunny day in cooling period (28th June 2010), the daily solar collector efficiency reached 32%, the thermal COP was 0,75, and the electrical COP reached 5,68. And for the heating period, the daily electrical COP can go up to 15 for very sunny winter days. System reliability and overall success of the installation The system has been working properly for more than 1.5 years on cooling and heating mode. The overall electrical COP (electrical efficiency of the solar system) has reached an average of 5.37 on a yearly monitoring duration. The building owner is satisfied by the solar cooling and heating system. The main conclusions obtained regarding the performances analysis carried on are: - Excellent performances of the chiller. - Good behavior of the geothermal horizontal probes. - Good performances of the collector field considering they are flat plate collectors, but a lot of days are not sunny enough to start the solar system. - Difficulties to reach a high electrical COP due to the “experimental state” of the installation: explained by the presence of numerous pumps, of devices consuming more electricity than usually (hot tank, chiller), and of a large set of sensors (more numerous than in a “basic” page 29
