摘要
Abstract
A new type of hybrid desiccant air conditioning system combining an active desiccant wheel with a con -ventional pre-cooling coil is presented , in which the Type Ⅲ desiccant is used for the active desiccant wheel.Then a performance analysis is presented for investigating the feasibility of the hybrid desiccant system served as a dedicated outdoor air system ( DOAS).And the result shows: under two typical outdoor environment conditions in the area of South China , the desiccant system which only needs to adopt a regeneration temperature of 45℃ and does not need to lower the coil temperature can satisfy the demand for indoor humidity ; when operating in hot and humid climate with a high humidity of 90%and a temperature lower than 36.7℃, the desiccant system only driven at a regeneration temperature of 60℃can also provide enough dehumidifying capacity;but compared with the active desiccant wheel using a Type Ⅰor Type Ⅱ desiccant , this system can not deliver a lower supply air dew point.Therefore, this system can operate effectively with a moderate regeneration temperature and will be available to the high quality and comfortable space conditions.关键词
