The main goal of this Task is to investigate new or advanced solutions for
storing heat in systems providing heating or cooling for low energy
The first objective is to contribute to the development of advanced storage
solutions in thermal solar systems for buildings that lead to high solar
fraction up to 100% in a typical 45N latitude climate. The second objective is
to propose advanced storage solutions for other heating or cooling technologies
than solar, for example heat pumps or fossil boilers in order to reduce cycling
and thus to reduce pollutant emissions due to partial combustion.
The ambition of the Task is not to develop new storage systems independent of
a system application. The focus is on the integration of advanced storage
concepts in a thermal system (solar, heat pump or boiler) for low energy
housing. This provides both a framework and a goal to develop new technologies.
The Subtasks are:
- Subtask A: Evaluation and Dissemination (Subtask Leader in 2006:
- Subtask B: Chemical and Sorption (Subtask Leader: Chris Bales, Sweden)
- Subtask C: Phase Change Materials (Subtask Leader: Wolfgang Streicher,
- Subtask D: Water (Subtask Leader: Harald Drueck, Germany)
The teams within Subtasks B, C and D are asked to set up a TRNSYS model of
their system based on experimental work in order for Subtask A to compare all
the options in terms of heat and cold storage for a reference case of a single
family house in four climates.
