Then, three main subsystems have been considered: Cooling Machine, Hydraulic Network and Hydrosolar Roof. A description of the three subsystem is done and the mathematical model is presented.The Cooling machine thermodynamic model has been carried out using EES (Engineering Equation Solver). The Hydraulic network model has piping, pump and nozzle information. The Hydrosolar Roof direct contact heat and mass transfer simulation has been development with a CFD code. Special attention has been paid on the cooling efficiency. The global model has been applied to a real prototype facility experimentally tested. All the energy consumptions have been calculated for different pumping heads. A global coefficient of performance (COP) has been defined and the optimum value obtained. %K Mecánica de Fluidos %K Tamaño de gota %K Aire acondicionado %K Chimenea solar %K Torre de refrigeración %K Energía solar %K Drop size %K Air conditioning %K Solar chimney %K Cooling tower %K Solar energy %~ GOEDOC, SUB GOETTINGEN
