[en] The simulated cooling plant equips an office building
whose maximum cooling demand is about 5 MW. To
meet this load, the cooling plant uses five cooling
towers, four twin-screw chillers and four encapsulated
ice storage tanks.
The simulation of the cooling plant is carried out with
the software TRNSYS. To perform the simulation, the
system components are first modeled and identified on
the basis of the information given by the equipment
manufacturers and the installers.
Once the parameter identification of the components is
done, TRNSYS is used to simulate the cooling plant in
each operating mode. This paper focuses on two
operating modes : the pure discharging and the direct
production with possible discharging. For these modes,
a control strategy was developed during the cooling
plant design phase. This paper discusses the impact on
the plant performance of changes brought to the
designed control strategies
