abstract = {The control strategy strongly influences the performance of
adsorption chillers: both efficiency and cooling power
depend on phase times for adsorption and desorption. For a
given cooling power, operating points with maximum
efficiency are Pareto-optimal and desired in practice.
However, finding the corresponding phase times for
adsorption and desorption is difficult since these times
vary with system characteristics and inlet conditions. In
this paper, we mathematically derive a control strategy
which is based only on heat flow measurements in the
evaporator and the condenser of the adsorption chiller. The
derived control strategy finds the Pareto-optimal adsorption
and desorption phase times for a given cooling load. The
control strategy is easy to implement since it only requires
easily available temperature and volume flow measurements in
the secondary fluid circuits. The derived control strategy
is tested in (1) a simulation study and (2) an experimental
study. In the simulation study, we show that the control
strategy leads to (near) Pareto-optimal operation in cyclic
steady-state and quickly responses to step-changes in the
inlet conditions. In the experimental study, we demonstrate
the ease of implementation and we show optimal operation for
continuously varying inlet conditions.},
