| Abstract: | This paper presents an evaluation of various solid desiccant cycles for air conditioning in hot and humid
climates. Psychrometric evaluation of potential cycles for 16 typical Indian cities has been carried out with
the objective of achieving standard comfort conditions in the room. Computer simulation is based on
constant effectiveness of heat exchangers and evaporative coolers and actual performance data of a
commercially available desiccant wheel dehumidifier. The influence of various outdoor conditions, the
effectiveness of heat exchangers/evaporative coolers on the cooling coefficient of performance and volumetric
air flowrate per unit cooling capacity have been investigated. It is found that amongst ventilation,
recirculation and Dunkle cycles, the Dunkle cycle is better for a wide range of outdoor conditions. However,
cycles using wet surface heat exchangers give even higher performance. |
