| description | Desiccant wheels
are used as an air dehumidifier in air-conditioning and industrial
applications. Desiccant wheel performance determines the size and cost of the
whole system. A good desiccant wheel is one that saves energy usage. This
article presents an experimental investigation on the effects of varying the
regeneration air temperature, viz., 50, 60 and 70oC, on desiccant
wheel performance. Three performance criteria were considered, namely condition
of process outlet air, dehumidifier efficiencies and dehumidification rate. Two
kinds of efficiency of the desiccant wheel dehumidifier were examined, namely
thermal and dehumidification efficiency. Results of the experiments show that
increasing the regeneration air temperature increases the dry bulb temperature
of the process outlet air. However the moisture content of the process outlet
air is reduced. The dehumidification efficiency of the desiccant wheel
decreases with increasing regeneration air temperature, i.e., 46.7, 45.8 and
45.3 % for 50, 60 and 70oC, respectively. In contrast, the
dehumidification rate increases with an increase in the regeneration air
temperature, namely 32.6, 37.1 and 40.2 g/h for 50, 60 and 70oC,
respectively. |
