摘要
文章构建了由固体废弃物气化炉废热驱动的高效除湿空调系统,该空调系统利用除湿换热器承担湿负荷。此外,该空调系统内还设有回热装置,利用该回热装置能够显著降低实际能耗。文章在有、无回热子系统的情况下,分析了高效除湿空调系统的热湿传递特性,并得到了带有回热子系统的高效除湿空调系统的最优工况参数。分析结果表明:当驱动热源温度为70℃时,若高效除湿空调系统存在回热子系统,则该空调系统的平均除湿量达到了9.01g/kg;在有、无回热子系统的条件下,高效除湿空调系统的COP分别为0.7,1.34;当预再生时间为180s时,高效除湿空调系统的运行性能最佳。
A high efficiency dehumidification system driven by waste heat of gasification CHP subsystem is proposed. The desiccant coated heat exchanger is adopted to assume the dehumidification load of the system. Besides the heat recovery subsystem is added to significantly reduce the actual energy consumption of the dehumidification system. By experimental studies and optimization analysis of the dehumidification system, the heat and moisture transfer characteristics of the system with/without heat recovery subsystem were compared. The optimal operating parameters of the dehumidification system with heat recovery subsystem were obtained. Under the condition of heat source temperature of 70 ℃,the average moisture removal of the system reached 9.01 g/kg with heat recovery subsystem. Thermal COP increased from 0.7 to 1.34 thanks to the heat recovery subsystem. In addition,the influences of the heat recovery subsystem were analyzed. The optimization of the preregeneration time was analyzed. The operation mode with the pre-regeneration time of 180 s was recommended to achieve the best operation performance.
