Thermal comfort and pollutant transport prediction in the object oriented environment spark

A coarse-grid zonal model of room air convection is formulated and written with the SPARK object- oriented simulation environment. The model consists of a set of coupled equations determined by heat and mass balance on each of the cells into which the room is divided, convection from the room surfaces and radiant exchange among the room surfaces. The equations are first written in MAPLE, from where they are automatically translated into SPARK objects. The objects are connected to build the simulation. The resulting set of equations is solved iteratively with SPARK to determine the room air flow and temperature distributions. The last but one stage has been automated. So, the only thing the user has to do is to give the partitioning and to choose the models to be implemented. Representing a whole building using zonal models is now possible. Results of simulations in 3D-rooms will be presented.
