提出了一种新型再生式除湿换热器,建立了物理和数学模型。通过实验得到了该除湿换热器的实际动态除湿性能;将除湿器除湿性能的模拟结果与实验结果进行比较,验证了数学模型的可靠性。研究结果表明:该文研制的再生式除湿换热器具有良好的除湿性能,在给定工况(温度为24.7℃,含湿量为12.41g/kg)下除湿率可达到43.8%;还分析了处理风速、再生温度以及除湿换热器厚度对除湿性能和压降的影响,获得了使除湿换热器性能最佳的管排、翅片间距和迎面风速参数。
A new type of regenerative dehumidification heat exchanger is proposed. The physical and mathematical models are established. The actual dehumidification performance of the dehumidification heat exchanger was obtained through experiments. The simulation results of the dehumidification performance of the dehumidifier were compared with the experimental results to verify the reliability of the mathematical model. The results show that the regenerative dehumidification heat exchanger developed by this paper has good dehumidification performance, and the dehumidification rate can reach 43.8% at a given working condition (temperature 24.7 ℃ and moisture content 12.41g / kg) In order to deal with the influence of wind speed, regeneration temperature and dehumidification heat exchanger thickness on dehumidification performance and pressure drop, the optimal tube dehumidification, fin spacing and oncoming wind speed parameters were obtained.
