摘　　要：分析了制约现有溶液全热回收装置效率的主要因素,以内部驱动势分布均匀一致为原则,对溶液全热回收装置进行了优化分析,并给出了在不增加装置体积投入的前提下,提高热回收装置效率的有效措施。构建了溶液全热回收装置最高可达效率的处理流程,并分析实际装置接近可达效率的程度。By using liquid desiccant as the working media, the total heat energy exchange between outdoor air and indoor exhaust air can be realized, and cross-contamination can be avoided. The main factors which restrict the enthalpy recovery efficiency were analyzed, and the optimization analysis on the enthalpy recovery device using liquid desiccant was then presented based on the principle of uniform heat and mass transfer driving force. The effective method to improve recovery efficiency and the maximal reachable efficiency with certain mass flow rate and NTU value were constructed, and the difference between real and ideal device was also disussed.
