“…The primary purpose of modern air‐conditioning design is to achieve compact and energy‐efficient air‐conditioning systems for creating human thermal comfort conditions on a global scale. In recent decades, with the population growth and the need for creating comfortable living conditions, attention to novel systems such as membrane‐based air‐conditioning (HMBAC) systems as a sustainable alternative to conventional vapor compression air‐conditioning systems is developing rapidly 1 . HMBAC systems can reduce fossil fuel consumption and reduce environmental impacts.…”

“…In previous work, 1 an HMBAC system was designed, and a mathematical model simulation was carried out. It was found that increasing the stage cut from 0.01 to 0.1 and increasing the pressure ratio up to 20 increased the system's cooling capacity at about 3.3 kW and power consumption up to 434 W simultaneously.…”

Various parameters have an impact on the fresh air temperature and input power of a hybrid membrane-based air conditioning (HMBAC) system, such as pressure ratio, membrane selectivity, membrane permeance, membrane area, air flowrate of the dehumidification unit, and module length, number of fibers, and fiber outer diameter of the humidification unit, which comprise both operational and structural parameters. Therefore, in this study, the effects of these parameters on the system performance are examined separately based on a statistical approach. The importance order of each parameter and its contribution ratio are determined by using Taguchi method and ANOVA analysis. The optimum level for each input parameter is determined using statistical analysis for the fresh air temperature and input power. Then, for the simultaneous minimization of fresh air temperature and input power Taguchigray relational grade (GRG) is used. GRG revealed that membrane selectivity, pressure ratio, and membrane permeance with the contribution ratio of 37.87%, 32.51%, and 10.55%, respectively, are the most critical parameters of the multiperformance of an HMBAC system. Interestingly dehumidification from a humid airflow can be more effective when membranes with low selectivity and high permeability are used.In conclusion, the optimization outputs disclosed that both structural and operational parameters have significant effects on the performance of the HMBAC system and this optimization can be a helpful tool for designing a HMBAC systems to cover the optimal conditions to develop a sustainable membrane-based air conditioning system.

The current standard of residential buildings is based on well-insulated and airtight construction as an effective way to reduce primary energy consumption. On the other hand, this intensifies the issue of the indoor air quality. In this paper, the applicability of a hybrid dehumidification/evaporative cooling system for the processing and supply of fresh air is evaluated. The proposed novel system employs cross-flow hollow-fiber membrane modules. To provide a better insight into this novel approach, the system’s performance is numerically investigated using a validated mathematical model. The proposed fresh air processing system provides supply air parameters in or close to the summer comfort range. The analyzed system is characterized by a high coefficient of performance (COP) of up to 33.2 at an outdoor air temperature in the range of 30 °C to 38 °C and a humidity ratio in the range of 8 g/kg to 14 g/kg. Moreover, a temperature difference of up to 9.7 °C can be obtained after the two-stage membrane processing and the mixing process.
