A new type of hybrid desiccant air conditioning system combining an active desiccant wheel with a conventional front-positioned cooling coil is presented, in which Type Ⅲ desiccant is used in the active desiccant wheel. Then a preliminary experiment is carried out in order to investigate the feasibility of the hybrid desiccant system serving as a dedicated outdoor air system (DOAS). The result shows: under the two typical outdoor air conditions in the area of South China, the desiccant system which only needs to adopt a regeneration temperature of 45°C without lowering the cooling coil temperature can satisfy the requirements of the dehumidification; when operating in the climate with a high humidity of 90% and a high-temperature of no more than 36.5°C, the desiccant system only driven at a regeneration temperature of 60°C can also provide enough dehumidifying capacity; but compared with the active desiccant wheel using Type Ⅰor Type Ⅱ desiccant, this system can not reach a lower dew point. Therefore, this system can operate effectively at a moderate regeneration temperature, suitable for the high quality and comfortable air conditioning.
