abstract = {Thermally-driven sorption chillers offer a sustainable
alternative to compression chillers. However, the expected
benefits of sorption chillers are often not realised in
practice due to high electricity consumption of auxiliaries,
such as pumps and fans. To obtain an overall optimal full
sorption chiller system, we propose a method for integrated
optimisation of design and control. The proposed method
applies dynamic optimisation to identify optimal control for
each investigated system design. Thus, each design is
evaluated under optimal control regarding a problem-specific
objective, such as electrical efficiency or total costs. We
illustrate the method for a case study of a
solar-thermally-driven adsorption chiller system. The
results are compared to an established design method and
nominal control: optimising for electricity demand allows to
increase the electrical energy efficiency ratio (EER) by one
order of magnitude. When optimising for total costs, optimal
control increases the energy efficiency by a factor 4 and
decreases the total costs by $28\%$ to 0.13 EUR/kWh. Moving
to a cost-optimal design further increases the energy
efficiency by $50\%$ to 16.2 and reduces the total costs by
another $8\%.$ Thus, the proposed method allows for
efficient integrated design and control of full sorption
chiller systems.},
