Energy Performance and Thermal Comfort Delivery Capabilities of Solid-Desiccant Rotor-Based Air-Conditioning for Warm to Hot and Humid Climates—A Critical Review

There has been considerable research worldwide on desiccant-based air-conditioning during the past 30 years. The rationale for push this new focus twofold: (a) need to provide an alternative conventional refrigerative systems which rely heavily fossil fuels as their energy sources, and (b) better thermal comfort in air-conditioned spaces warm hot humid climates. A desiccant system consists of several components cool dehumidify air before it is supplied a conditioned space. Earlier work identified potential advantages technology, include following: (1) working fluids that do not impact ozone layer, (2) reduced electricity consumption, (3) improved indoor quality, (4) simpler construction less maintenance, (5) integral provision heating cooling cold/temperate On other hand, authors paper following drawbacks: inevitable while being dehumidified, regeneration low COP paradox, limited options heat reliable cooling, electrical coefficient performance (COP). This presents critical review solid-desiccant rotor-based systems, discusses detail drawbacks. found drawbacks outweigh advantages. main reason dehumidified counterintuitive addition moisture evaporative process. During years development efforts, no significant innovations have discovered resolve these crucial issues. Unless future directed find breakthrough, technology will commercial application.
