Results and evaluation of the prototype operation of an open sorption based air-conditioning system under tropical climatic conditions in Singapore

A first prototype of an open sorption based ventilation device has been operated and investigated under tropical climatic conditions in Singapore. The technology behind is basing on the principle of the ECOS (Evaporatively COoled Sorptive Heat Exchanger), sorptive coated air-to-air heat exchangers, which allow the combination of sorptive dehumidification with simultaneous indirect evaporative cooling. The results show the potential of the desiccant-based ventilation system in handling the latent as well as a small part of the sensible loads. The analysis underlines the energy efficiency of the approach characterized by the combination of dehumidification of the supply air with additionally installed chilled beams which can be operated with high chilled water temperatures.
