A bump, because I found this site which mentions another way of doing it, but doesn’t provide very many details on how it works.
The desiccant cooling cycle is a novel open heat driven cycle which can be used both to cool and dehumidify air. Being a heat driven cycle, desiccant cooling affords an opportunity to utilise heat which might otherwise be wasted. It can therefore be coupled to solar collectors to produce a cooling system which, in theory, should be extremely environmentally friendly. This paper discusses the feasibility of using solar energy to power the desiccant cooling cycle and also presents the results of a recent study, in which a solar desiccant cooling model is used to evaluate a theoretical installation located in the southeast of England. The paper demonstrates that solar powered desiccant cooling is a feasible solution for cooling and heating buildings in the United Kingdom (UK).
I’d be interested to see the details on how it operates.
The solar heat is ustilized to regenerate the dessicant or moisture adsbortion material whch is then ready to take on more moisture which is evaporated from a soucre of water at a lowere temperature. No idea of system set up.
