Abstract

To allow for a de-coupling of the charging and discharging parameters, a dual-tube PCM storage unit using extruded aluminium fins was designed and built. This concept allows on the one hand for completely different media and flow parameters to be used, it also allows for temporally independent charging and discharging, simplifying system integration and control. This is a benefit for industrial systems, in which differing systems can be coupled through a storage unit, allowing for serial or parallel charging and discharging, with differences in power or capacity balanced by the storage unit. A 160 kWh storage unit has been analysed, designed, built and will be experimentally tested by the conference.
