Abstract :
[en] This paper is giving an overview of problems encountered and solutions available for the simulation of an air conditioning system. Focus is given on the chilling water subsystem (from the chiller to the cooling coil). Main component simulation models (chillers, pumps, piping, valves, cooling coils and fans) are presented; they are tuned on manufacturer’s catalogue data. The way of integrating these models into a global HVAC system simulation is illustrated thanks to one example: the simulation of (a part of) a real chilled water loop, which is submitted to an exhaustive monitoring. Cooling demands and corresponding energy consumptions are systematically simulated and measured on one-minute time basis. This provides the opportunity for a global checking of the simulation by comparing simulated and measured cooling coil outputs. Further work should also include comparisons on chiller consumptions.
