液-气膜能量交换器（LAMES）通过蒸汽渗透膜在液体干燥剂溶液和气流之间传递热量和水分。液体除湿膜空调（M-LDAC）系统是为满足建筑物的潜在或除湿负荷而设计的。与传统空调（CAC）系统相比，M-LDAC系统更适合除湿空气。提高LAMES性能的一种方法是在溶液通道内安装冷却/加热管，以控制溶液温度- 真的在跛脚里面。这种换热器被称为三流体换热器。本研究的主要目的是开发三流体LAME的瞬态系统仿真（TRNSYS）模型，并使用它来模拟低、中、高潜在负载条件下三流体M-LDAC系统的性能。结果表明，在高、中潜载条件下，三流体M-LDAC系统的性能优于两流体M-LDAC系统，而在最低潜载条件下，两流体M-LDAC系统输出端形成了三流体M-LDAC系统。 引用:2019年年度会议，密苏里州堪萨斯城，技术论文

Liquid-to-air membrane energy exchangers (LAMEEs) transfer heat and moisture between a liquid desiccant solution and airstreams through vapor-permeable membranes. Liquid desiccant membrane air-conditioning (M-LDAC) systems imple-ment LAMEEs to meet the latent or dehumidification loads in buildings. M-LDAC systems are better suited to dehumidify air than conventional air-conditioning (CAC) systems. One way to enhance the performance of LAMEEs is to install cooling/heating tubes inside the solution channels to control the solution tempera-ture inside the LAMEE. Such an exchanger is called a three-fluid LAMEE. The main objectives of this study are to develop a Transient System Simulation (TRNSYS) model of the three-fluid LAMEE and use it to simulate the performance of a three-fluid M-LDAC system under low, medium, and high latent load conditions. The results show that the three-fluid M-LDAC system out performs the two-fluid M-LDAC system under the high and medium latent load conditions, whereas the two-fluid M-LDAC system outper-formsthe three-fluid M-LDAC system under the lowest latent load condition.
