France: Promising Monitoring Results of Solar-Cooling Hybrid Strategy

Submitted by Baerbel Epp on November 5, 2014
Hybrid Solar Cooling ConceptDuring the Task 48 meeting in Garching, Germany, at the end of September 2014, Daniel Mugnier, Head of Task 48 of the IEA Solar Heating and Cooling programme, presented the monitoring results of a promising demonstration project which integrates solar cooling technology into an existing building cluster. Engineered by Tecsol, the system has been supplying energy to two buildings housing offices and flats in Montpellier, in the south of France, since May 2012. The special characteristic of the system owned by the SERM (Société d’Équipement de la Région Montpelliéraine) is a hybrid mode in which the 240 m2 field with double-glazed collectors supplies heat to a single-effect lithium-bromide absorption chiller in summer, as well as domestic hot water to the block of flats all year round. During the main cooling season in July and August, the electrical coefficient of performance (COP) showed a very high average of 12, while the measured thermal COP during the same period was, on average, 0.6.
