Liquid to air membrane energy exchangers

A liquid to air membrane energy exchanger (LAMEE) can be used as part of a heating and cooling system to transfer heat and moisture between a liquid desiccant and an air stream to condition the temperature and humidity of the air flowing through the LAMEE. The membrane can be a non-porous film having selective permeability for water, but not for other constituents that form the liquid desiccant. The non-porous membrane can allow for use of liquid desiccants, such as glycols, that had been previously determined to be unacceptable or undesirable in these types of applications. In an example, the membrane can be an ion-exchange membrane or pervaporation membrane. 种液-气膜能量交换器(LAMEE)可以用作加热与冷却系统的部分，以在液体干燥剂和空气流之间转移热量和水分，以调节流动通过LAMEE的空气的温度和湿度。该膜可以为无孔薄膜，其对于水具有选择性渗透性，但是对形成液体干燥剂的其他成分没有渗透性。该无孔膜可以允许使用之前确定在这些类型的应用中不可接受或不期望的诸如乙二醇的液体干燥剂。在个实例中，膜可以为离子交换膜或渗透蒸发膜。
