Engineering and set-up of a new testing facility for solar thermal systems
At the Fraunhofer ISE a testing facility for solar domestic hot water systems (thermosiphon systems, systems with forced circulation, integral collector-storage systems) and heat storages is already in operation since 1997.
Now a new testing facility has been engineered to satisfy the growing demand for the tests on solar domestic hot water systems according EN 12976 [1]. This testing stand provides the possibility to perform tests of four different systems at the same time and independently.
The testing facility and its sensors fulfils very high testing and measuring requirements. The boundary conditions during testing can be handled in a far better way than in the previous test stand. This concerns, for example, the cold water inlet temperature during the tests and the ambient temperature of the storage tank.
The testing facility is designed for tests on complete solar heating systems and heat storages.
