IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report, Date:… 1 Background The targeted building welcoming the solar cooling application is the Résidence du Lac, a building dedicated to retired people. This building is located in the small town of Maclas in the Rhône Alpes area, close to Lyon. The town is in altitude, nearly 450 m high. The building was created in the seventies and is of an average quality level for the energy efficiency. Only one small part of the building is cooled, the leisure space/restaurant which is compulsory since summer 2003 in retired buildings. This area is of 210 m² and includes a veranda oriented in the Southern direction. Efforts were made to increase the solar protection level in the veranda by adding dark thin protection films. Till 2007, the building owner used electric compression chillers (3 monosplits). Two of them were out of order in 2007 and the management took the decision with the help of the SIEL (Syndicat Intercommunal d’Energie de la Loire) to go for a solar cooling system. The owner of the system is the SIEL itself. 2 System Design The system is based on an absorption chiller of 10 kW coupled with evacuated tube collectors. The system is in configuration of a quasi solar autonomous cooling system because only a small electric compression chiller (split type) is used in case of failure of the solar system. The load of a part of the entire building is based on the following scenario: cooling demand from June to mid September and heating demand from mid October to end of May. The solar system is using fan coils for the cooling and heating modes but thanks to buffer storage, it can be valorized as well in the heating mode through the central heating network of the Résidence du Lac. The heat rejection system is done by a drycooler located in the northern facade of the building. Installation’s scheme: Hydraulic scheme of the Maclas installation
