摘　　要： 提出了分级再生式转轮除湿和蒸发冷却相结合的空调系统,依据除湿和再生过程的质量守恒和能量守恒方程,结合边界条件和初始条件建立除湿转轮和空调系统的数学模型,对比分析了分级再生空调系统的性能。研究结果表明:采用分级再生的转轮可达到与一般再生转轮相同的除湿效果。与一般再生的空调系统相比,分级再生式空调系统的再生能耗降低了约50%,热力性能系数提高了约90%。 A desiccant and evaporative cooling system with staged - regeneration was proposed. According to the mass and energy conservation equation in the dehumidification and the regeneration process combined with the boundary and initial conditions, the mathematical model of the desiccant wheel and air conditioning system was established. The results showed that the desiccant wheel with staged regeneration could achieve the same dehumidifying effect. Compared with the air conditioning system with general regeneration, the energy consumption for regeneration of the system with staged - regeneration could decrease about 50%, and the thermodynamic coefficient of performance could increase about 90%.
