摘要/Abstract

摘要：

首先讨论了在已知负荷及新风量的条件下,为了使得固体吸附除湿空调整体能耗最低,确定最佳送风状态点的方法,然后讨论了固体除湿空调系统整体能耗与所选用的吸湿剂吸附水蒸气的吸附热之间的关系,以及与传统的冷凝除湿相比,新型空调系统的能耗水平。结果表明,吸附除湿空调器的能耗与吸附热的关系密切,合理选择吸湿剂,不但空调器的能耗比冷凝除湿更低,尤其是空气的除湿负荷较大时效果更为明显,而且送风温差小,可获得更好的舒适性。

Abstract:

The method for determining the best air state point is investigated for a given cooling load and the fresh air volume. Then the relationship between the heat of adsorption of water vapor and the overall energy consumption of solid desiccant air conditioning system is discussed, finally the energy consumption of the novel air conditioning system is compared with conventional condensation dehumidifier. The results showed that the energy consumption of solid desiccant air conditioner is closely related with the heat of adsorption, a reasonable choice hygroscopic agent, not only the energy consumption of the air conditioner condensation dehumidifier is less, especially when a large dehumidification load is treated, the energy saving effect is most obvious. Besides, the supply air temperature difference is smaller, which is helpful for a better comfort indoor air-conditioning environment.

Key words: solid adsorptive dehumidification, dehumidification heat exchanger, condensation heat recover
