Generalization in plant component modelling

In computer simulation, accurate modelling of air conditioning equipment is important in the studies of dynamic plant performance, for instance in the selection process of a plant control scherne, in the investigation of plant energy consumptions, or in the detailed design of a plant equiprnent. With the advancements in computer speed and manmachine: interface, a new generalized plant simulation approach can be used which represents the energy and mass flow paths by the primitive parts as the basic elements in constructing plant components. This paper explains the mathematical concepts and presents some illustrative examples with simulation results validated by analytical solution and inter-model comparisons. Advantages and possible future developments are also addressed.
