本文分析并报道了一种结合不同太阳能集热器的鼓泡塔增湿型海水淡化系统。该系统的主要组成部分是加湿器，除湿器，太阳能空气加热器（SAH）和两用收集器（DPC）。通过将HDH系统与常规太阳能空气加热器集成（情况I）、通过与包含加湿器的太阳能空气加热器集成（情况II）以及通过与包含加湿器的双用途太阳能收集器集成（情况III）来进行三组实验。在太阳能集热器的空气流场中设置扰流器，提高了出口空气的温度。空气和水在两用收集器中同时加热并供应到加湿器。所有实验都是通过改变空气（0.014 kg/s至0.018 kg/s）和冷却水（0.025 kg/s至0.058 kg/s）的质量流量来完成的。随着空气和冷却水流量的增加，系统的性能得到改善。在情况I、情况II和情况III中分别观察到约2、2.8、3.3的获得的产出比和约16.32、20.61、23.92 kg/m2/天的生产力。使用情况III配置实现了0.019 $/kg的最低蒸馏水成本。
A bubble column (BC) humidification dehumidification (HDH) desalination system integrated with the different solar collectors is analyzed and reported in this work. Major components of the systems are a humidifier, dehumidifier, solar air heater (SAH), and dual purpose collector (DPC). Three set of experiments is performed by integrating the HDH system with conventional solar air heater (case I), by integrating with solar air heater containing turbulators (case II), and by integrating with dual purpose solar collector containing turbulators (case III). Turbulators in the air flow field of solar collector enhances the exit air temperature. The air and water are simultaneously heated up in the dual purpose collector and supplied to the humidifier. All the experiments are done by varying the mass flow rate of air (0.014 kg/s to 0.018 kg/s) and cooling water (0.025–0.058 kg/s). The performance of the system is improved with the increase in air and cooling water flow rate. Gained output ratios of about 2, 2.8, 3.3 and productivities of around 16.32, 20.61, 23.92 kg/m2day are observed in the case I, case II and case III respectively. The minimum distilled water cost of 0.019 $/kg is achieved with the case III configuration.
