Independent air dehumidification provides an attractive alternative to traditional coupled air dehumidification with reduced energy use, better humidity control and indoor air quality. According to this concept, latent load is treated by an independent system and the sensible load is treated by chilled-ceiling panels. In this work, four independent air dehumidification systems with energy recovery strategies are proposed. They are as follows: system 1, mechanical dehumidification with heat pump; system 2, mechanical dehumidification with sensible heat exchanger; system 3, mechanical dehumidification with membrane-based total heat exchanger; and system 4: a heat pump incorporating an active desiccant wheel and evaporative cooler. They are compared with a mechanical dehumidification system with no heat recovery. Hour-by-hour energy analysis is performed on the systems proposed. The results show that the system of mechanical dehumidification with membrane total heat recovery (system 3) consumes the least primary energy. However, since, the systems employ energy recovery measures, the energy savings for the four systems are in the same order, around 4.40×10 kJ per person.
独立空气除湿提供了一种有吸引力的替代传统耦合空气除湿的方法，具有降低能源消耗、更好的湿度控制和室内空气质量。根据这一概念，潜热负荷由独立系统处理，显热负荷由冷顶板处理。在这项工作中，提出了四种具有能量回收策略的独立空气除湿系统。它们如下：系统1，带热泵的机械除湿；系统2，带显热交换器的机械除湿；系统3，带基于膜的全热交换器的机械除湿；系统4：结合主动式除湿转轮和蒸发冷却器的热泵。将它们与无热回收的机械除湿系统进行比较。对所提出的系统进行逐小时能量分析。结果表明，带膜全热回收的机械除湿系统（系统3）消耗的一次能源最少。然而，由于这些系统采用了能量回收措施，四个系统的节能效果处于同一水平，每人约为4.40×10⁶kJ。
