*5.3. Suitability of the Chilled Water System for Energy Flexible Operation*

The results of the suitability analysis for energy flexible operation of the system are presented in Table 6. Regarding its controllability: as the system is used for air temperature conditioning, it is state variable, outdoor temperature-dependent and hence can be classified as a Co1. As there is high redundancy in the system and it belongs to the TBS technical unit, its criticality is estimated at a Cr3. This because a change of state in the system is neutral for process continuity as long as the demand is met. Finally, the interdependence is given as In1, as the system counts just the inherent thermal inertia across in the chilled-water-piping grid and the conditioned rooms.
