Résumé

Desiccant and evaporative cooling are alternatives to compressor driven air conditioning systems. In low load buildings, the indirect evaporative cooling system can be sufficient to reach comfort. In high load buildings, the desiccant cooling mode can take over from indirect evaporative cooling but in very high load buildings, it turns out to be inadequate. The limits of feasibility of the indirect evaporative system and desiccant cooling systems have been assessed. The methodology is based on simulations, which have been carried out for different temperate climatic zones, different thermal inertia levels, different internal load levels and different solar gain levels. The annual energy consumption has been assessed. Since water consumption cannot be neglected when considering operating costs, it has been evaluated.
