Thermal solar systems and components. Custom built systems - Performance test methods for solar combistores

DD CEN/TS 12977-4:2010 Thermal solar systems and components. Custom built systems. Performance test methods for solar combistores

DD CEN/TS 12977-4 is a Technical Specification which specifies test methods for the performance characterization of stores which are intended for use in small custom built systems.

Stores tested according to this document are commonly used in solar combisystems. However, also the thermal performance of all other thermal stores with water as storage medium (e.g. for heat pump systems) can be assessed according to the test methods specified in this document.

DD CEN/TS 12977-4 applies to combisstores with a nominal volume up to 3 000 l and without integrated burner.

DD CEN/TS 12977-4 is extensively based on references to BS EN 12977-3:2008.
