英文摘要：

Membrane-based heat and moisture treatment is a novel temperature and humidity control technology for energy conservation in buildings. Its moisture control effectiveness is high, and it is compact. Moreover, the traditional problem of desiccant droplet crossover is prevented. In recent years, much progress has been made in the development of this technology, from fundamentals to applications. In this review, advances are introduced, including novel membrane materials, new findings in conjugate heat and mass transfer in membrane modules, and new systems that combine air dehumidification with renewable energy use. A membrane made of a uniform material is weak on mass transfer and not suitable for engineering applications. A composite hydrophobic-hydrophilic membrane can substitute for it because of the reduction in mass transfer resistance. The heat and moisture transfer mechanisms in parallel plates, plate fins, and cross-eorrugated membrane-based total heat exchangers are discussed. The heat and mass transfer properties in hollow fibers modules are described. The conjugate heat and mass transfer on the surface membrane, flow mal-distribution in the membrane modules and the randomly distributed nature of heat in the tube banks are ideal for application in dehumidification systems. Their effects on heat and mass transfer are presented. The correlations for heat and mass transfer, and the detailed Nusselt and friction data for module design, are summarized. They provide the fundamentals for system design and optimization. Moreover, the heat and mass entransy dissipation, which is a new concept in thermodynamics, is introduced to analyze the system performance. It is found that the larger the heat and mass entransy dissipation, the more heat is lost and the more irreversible the mass transfer for air dehumidification. In addition, the system set-up and the applications of this new technology are introduced. The heat pump driven liquid dehumidification systems perform well because the cooling and heating before dehum
