| 摘 要： | 建立了焓轮式全热回收器的数学模型，并利用此模型研究了硅胶、氯化锂和硅胶-氯化锂复合材料作为吸湿剂时，转轮转速、转轮厚度和迎面风速的变化对回收器焓回收效率的影响。结果表明，对于焓轮式全热回收器，复合干燥剂与硅胶和氯化锂相比具有更大优越性，且存在最佳的转轮转速、转轮厚度和迎面风速，在计算条件下，对应各参数值分别为12 r•min-1、100 mm 和1.2 m•s-1。

| Abstract: | The mathematical model of enthalpy recovery wheel is established.Based on this model, the effects of wheel thickness, wheel rotational speed and air velocity on the enthalpy recovery efficiency of enthalpy wheel are investigated.Three different desiccants, namely silica gel, lithium chloride and silica gel-lithium chloride composite, are used as desiccant material. The results demonstrate that, silica gel-lithium chloride composite desiccant is the first choice for enthalpy recovery wheel in comparison to silica gel and lithium chloride.And there exist optimal rotation speed, wheel thickness and air velocity.For silica gel-lithium chloride composite, the corresponding values are respectively 12 r•min-1, 100 mm and 1.2 m•s-1 under calculation conditions. |
