【摘要】 基于传统的翅片管式换热器,本文研制一种再生式除湿换热器,此新型换热器通过粘结剂将硅胶颗粒涂覆在翅片和铜管外表面上。通过实验研究分析这种新型除湿器的性能。在实验过程中,测试处理风速、再生温度以及入口空气含湿量对除湿换热器性能的影响。此外在上海工况下分析不同再生温度下系统的太阳能利用效率。研究结果表明此类换热器有望在太阳能空调,环境湿度处理等领域获得广泛应用。更多还原

【Abstract】 A new type of regenerative desiccant heat exchanger was proposed and developed based on the traditional style of fin-tube heat exchanger. Silica gel was coated to all the surfaces of fin and copper tube of the dehumidifier. The actual dynamic dehumidification performance of the desiccant system was obtained experimentally, and effects of velocity, regeneration temperature and inlet moisture on system performance were analyzed in the experiment. Besides, take Shanghai as an example, the solar energy use efficiency under a variety of regenerate temperature are analyzed. The results show that this type of desiccant heat exchanger is expected for wide use in the field of solar air conditioning and dehumidification.更多还原
