摘要：

Experimental investigations were carried out to determine the performance of a rotating desiccant wheel with chilled ceiling panels for humid climates in Malaysia. Dehumidification capacity was in the range of 0.89-2.673 kg/h. Relative humidity reduction to 40% with high dehumidification capacity of 2.673 kg/h was achieved within 10 min with air flow rate 01 243 kg/h. Chilled ceiling surface temperature between 14 and 18 degrees C was achieved by varying the chilled water inlet temperature from 6 degrees C to 10 degrees C at steady state. Condensation was absent on the chilled ceiling surface panels below 70% relative humidity. Thermal comfort room temperature for this investigation was 24-24.5 degrees C for chilled ceiling height of 2 m. (C) 2012 Elsevier B.V. All rights reserved.
