Performance of desiccant dehumidification with hydronic radiant cooling system in hot humid climates
Highlights ► Hydronic radiant cooling is an alternative to conventional air-conditioning system. ► Condensation is the great challenge for chilled ceiling panels in hot humid climate. ► Desiccant dehumidifier reduces energy consumption and improves indoor air quality. ► Reactivation is the main limitation of desiccant dehumidification system. ► Relative humidity at 50% and 60%, allows chilled ceiling to be in save operation.
Abstract 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 0.89–2.673kg/h. Relative humidity reduction to 40% with high dehumidification capacity of 2.673kg/h was achieved within 10min with air flow rate of 243kg/h. Chilled ceiling surface temperature between 14 and 18°C was achieved by varying the chilled water inlet temperature from 6°C to 10°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°C for chilled ceiling height of 2m.
