由上述设备实现的两级溶液除湿空调的降温除湿方式为：处理空气(室外空气或者室内外混合风，简称处理空气)由处理风风道16入口进入风机，然后进入第一填料塔模块1，空气中的水分被除湿溶液吸收，释放出热量，空气的温度升高。若继续除湿，则除湿效果将变差。因此该处理空气接着进入叉流换热器2，将热量传给换热器另一侧的冷却空气。然后降了温的空气再进入第二填料塔模块3，空气中的水蒸气为除湿溶液进一步吸收，成为含湿量较低的空气。同样，伴随水分的转移，空气的温度会升高。最后空气进入第四填料塔模块4，部分水分蒸发到空气中，空气温度下降，从而达到舒适的送风湿度工况。The cooling and dehumidification method of the two-stage solution dehumidification air conditioner realized by the above equipment is as follows: the treated air (outdoor air or indoor and outdoor mixed wind, referred to as treated air) enters the fan from the inlet of the treated
本发明与传统的液体除湿空调相比，该空调的分层设计极大的节省了空间，除湿模块的并联布置方便各级的气液流量比调节，大浓度差运行有利于充分发挥溶液的除湿能力，实现蓄能和节能的目的。除湿模块两级间蒸发冷却器以及叉流换热器的引入，充分利用自然冷源冷却处理空气，从而改善了除湿过程中气液混合热所导致的除湿效果的恶化。使用两级除湿填料塔模块，一个再生填料塔模块，结合叉流换热器和蒸发冷却填料塔模块，主要依靠太阳能集热器作为热源。本设备可用于商业建筑、民用建筑等场合的空气调节。Compared with the traditional liquid dehumidification air conditioner, the present invention has a layered design that greatly saves space, the parallel arrangement of the dehumidification modules facilitates the adjustment of the gas-liquid flow ratio at all levels, and the large concentration difference operation is conducive to fully exerting the dehumidification of the solution ability to achieve the purpose of energy storage and energy saving. The introduction of the evaporative cooler between the two stages of the dehumidification module and the cross-flow heat exchanger makes full use of the natural cooling source to cool the processed air, thereby improving the deterioration of the dehumidification effect caused by the mixed heat of gas and liquid during the dehumidification process. Using two-stage desiccant packed tower modules, a regenerative packed tower module combined with cross-flow heat exchangers and evaporative cooled packed tower modules, mainly relying on solar collectors as heat sources. This equipment can be used for air conditioning in commercial buildings, civil buildings and other occasions.
