Simulation of the Climate System Performance of a Museum in Case of Failure

The paper presents the evaluation of the current HVAC components and indoor climate of a high tech Naval Depot in case of failure events. The methodology of the research was: First, implementation of the heat, air & moisture models of the building and HVAC components in SimuLink. Second, validation of the models using measured data from the present building control system. Third, simulation of the current and new HVAC systems designs. Fourth, discussion of the usability of the approach. For this specific case, it is concluded that the current system design performs well if in case of a fault, the air supply to the depots is switched off automatically. The construction of the depots contains sufficient thermal inertia to maintain a stable indoor climate for a longer period in which the system fault can be repaired. A further improvement of the design could be to control the indoor climate surrounding the depots instead of inside the depots itself. In this case, even if the system would not detect a fault and thus supplying uncontrolled air at the surroundings of the depot, the indoor climate in the depot would remain stable. Furthermore it is concluded that the approach presented in this paper appears to be wider applicable than this single case study.
