Desiccant cooling is a potentially environmentally friendly technology which can be used to cool buildings without the use of traditional refrigerants. We have studied the operation of a desiccant cooling system in France. It is used to meet the cooling demand of a training room containing 40 persons. In order to decrease the system primary energy requirement, free cooling techniques are used. Models are implemented in SimSPARK a simulation environment able to solve complex problems. Simulations are run for several French cities. Results indicate that, as outdoor humidity ratio increases, regeneration energy increases. Using free cooling with ventilation and direct humidification can decrease regeneration energy requirement between 15 and 25%.
