The fluctuating availability of renewable energy sources poses a challenge in the planning and design of renewable building energy systems. The storage capacities required in a system depend both on the control strategy used and on the temperature-dependent efficiencies of the system components. More precise insights into the operating behavior of an overall system can be provided by dynamic simulations, which allow an analysis of the system temperatures and partial energy parameters.
In planning practice, for example, the question often arises as to the correct dimensioning of the heat supply (here: collector area) and the correct coordination of the storage tank in the overall system (here: storage tank volume).
With the help of an analysis of dynamic temperature curves in the system, transient operating states and time-variable power curves, critical system states can be identified and the individual components can be appropriately dimensioned.

The present project focuses on the operation of the adsorption chiller in summer. With the help of an analysis of dynamic temperature curves in the system, transient operating states and time-variable power curves, critical system states can be identified and the individual components appropriately dimensioned.

Solar-thermal driven adsorption chillers can be used profitably in terms of energy economy if they are operated year-round in combination with a compression chiller in a hybrid overall system. In such a flexible system, the solar heat can then also be used in winter for direct heating or as an (additional) heat source for the reversible heat pump.
