Résumé

The authors propose an HVAC system combining chilled ceilings with desiccant cooling for hot and humid climates where air dehumidification is required to maintain the indoor air humidity within the comfort zone and to reduce the risk of condensation on chilled panels. They consider that with this system, temperature and humidity control are decoupled by using a desiccant wheel for moisture removal and ceiling panels for temperature control. The results indicate that a chilled ceiling combined with desiccant cooling could save up to 40% of primary energy consumption in comparison with a conventional constant volume all-air system.
