Performance evaluation and optimization of solar rotary desiccant dehumidifier

为提升太阳能转轮除湿系统性能,文中开展太阳能转轮除湿系统性能研究以及运行模式优化。利用TRNSYSY软件建立太阳能转轮除湿模型,考察进行不同气候条件下太阳能转轮除湿系统性能分析,动态模拟不同再生热源的转轮除湿系统性能。研究结果表明:兼顾气候条件、系统的除湿量与除湿有效时间,太阳能转轮除湿系统更适用于高温高湿气候条件;根据广州市天气湿度或新风量要求,系统全年分阶段采取不同再生空气流量(处理空气流量)调控方法满足除湿要求;在广州地区太阳能转轮除湿系统选择55—60℃辅助加热模式较为合适。

Development and optimization of rotary desiccant dehumidifier system with solar energy as heat source were proposed by TRNSYSY software to improve the performance of solar rotary desiccant dehumidifier.The solar rotary dehumidification model was established to simulate the performance of solar rotary desiccant dehumidifier system under different climatic conditions and the system performances with different regeneration heat resources were simulated dynamically.The results show that the solar rotary desiccant dehumidifier is more suitable for high temperature combined with different conditions considering the climatic conditions,dehumidification capacity and effective time.According to the requirements of weather humidity or fresh air in Guangzhou,different controlling methods of regeneration air mass flow rate(process air mass flow rate)are adopted timely with the requirements of dehumidification or fresh air in stages throughout the year.The auxiliary heating mode of 55-60℃is more suitable for solar rotary desiccant dehumidifier in Guangzhou.
