摘要： 新风产品的性能在很大程度上取决于全热交换芯体中的多孔聚合物膜材。为了研究膜材关键参数的影响,将商用电池隔膜表面涂覆水性丙烯酸树脂制备了新型多孔聚合物膜,并分别通过支撑层与致密层的配方调控,证实了膜材的本征参数与膜材性能及芯体性能间的影响关系。此外,利用拟合公式得到了膜材传质性能-湿度效率与传热性能-温度效率的量化模型。在湿度效率和温度效率均提升5%的目标下,膜材水蒸气透过率需从2155 g·m^-2·day^-1提高至2356 g·m^-2·day^-1,导热系数需从0.42 W·m^-1·K^-1提升至4.5 W·m^-1·K^-1。此外,为了达到C1泄漏等级要求,膜材的CO₂透过率需低于1.047×10⁷ cm³·m^-2·24 h^-1·0.1 MPa^-1。

Abstract: The performance of fresh air products largely depends on the porous polymer membrane material in the total heat exchange core. In order to study the influence of membrane parameters, novel porous polymer membrane was prepared by coating a commercial battery separator with waterborne acrylic resin. By adjusting the formulations of the support layer and dense layer, the influence of the membrane’s intrinsic parameters on its performance and the core’s performance was confirmed. Additionally, quantitative models for the membrane’s mass transfer performance-humidity efficiency and heat transfer performance-temperature efficiency were established using fitting formulas. To achieve a target improvement of 5% in both humidity efficiency and temperature efficiency, the water vapor transmission rate of the membrane needs to increase from 2155 g·m^-2·day^-1 to 2356 g·m^-2·day^-1, and the thermal conductivity needs to increase from 0.42 W·m^-1·K^-1 to 4.5 W·m^-1·K^-1. Furthermore, to meet the C1 leakage level requirement, the CO₂ transmission rate of the membrane must be below 1.047×10⁷ cm³·m^-2·24 h^-1·0.1 MPa^-1.
