Abstract A novel hybrid system primarily consisting of a photovoltaic module (PVM) and a direct contact membrane distillation (DCMD) is proposed, where the relatively long wavelength sunlight transmitted through the PVM is converted into heat and then supplied to the DCMD for water purification. The models of both PVM and DCMD are mathematically formulated and validated, and the performance of the hybrid system is evaluated by considering the benefits of the addition of DCMD. Numerical calculation results predict that maximum energy efficiency (MEE) and maximum power density (MPD) of the hybrid system are, respectively, 60.73% and 607.29 W m−2, which are dramatically greater than that of the single PVM of 11.15% and 111.48 W m−2. The proposed hybrid system is demonstrated to be an effective architecture to enhance the energy conversion efficiency. Extensive parametric analyses are undertaken to explore how the hybrid system performance is affected by some important operating conditions, including feed water temperature, permeate water temperature, flow velocities of feed water and permeate water. Furthermore, the specific performances of the hybrid system and DCMD are studied under the maximum power condition.

摘要 提出了一种主要由光伏组件 (PVM) 和直接接触式膜蒸馏 (DCMD) 组成的新型混合系统，其中通过 PVM 传输的相对长波长的阳光转化为热量，然后提供给 DCMD 进行水净化。PVM 和DCMD 的模型都经过数学公式化和验证，并通过考虑添加DCMD 的好处来评估混合系统的性能。数值计算结果预测混合动力系统的最大能量效率（MEE）和最大功率密度（MPD）分别为60.73%和607.29 W m-2，显着高于单PVM的11.15%和111.48 Wm-2。所提出的混合系统被证明是一种提高能量转换效率的有效架构。进行了广泛的参数分析以探索混合系统性能如何受到一些重要操作条件的影响，包括给水温度、渗透水温度、给水和渗透水的流速。此外，还研究了混合动力系统和DCMD在最大功率条件下的具体性能。
