针对极端热湿气候区气候特征
构建一种带有除湿/再生自循环结构的太阳能溶液除湿系统(LDDS-SC)
综合考虑系统除湿量和太阳能光/热面积的耦合关系
通过传热单元数-路易斯数(NTU-Le)模型进行数值求解
得到不同除湿-再生自循环回流比(Rd
Rr)匹配工况下单位太阳能集热器/光伏组件面积的系统除湿量。结果表明
典型工况(ma=1800 m3/h
ms=4.0 kg/s)下
该系统最大除湿量、单位集热器面积的系统除湿量、单位光伏组件面积的系统除湿量分别约为常规系统的2.5倍、15.1倍和6.2倍;通过优劣解距离法(TOPSIS)进行多目标决策得到该系统的最佳除湿-再生自循环回流比(Rd
Rr)为(0.9
0.1)
此时系统除湿量为4.61 g/s
单位总面积的系统除湿量为0.28 g/(s·m2)。表明LDDS-SC系统较常规溶液除湿系统具有更好的除湿和节能潜力。
Aiming at the climate characteristics of extreme hot and humid climate region
this study constructed a solar solution dehumidification system (LDDS-SC) with a self-circulation structure of dehumidification/regeneration. The coupling relationship between system dehumidification and solar light/thermal area was comprehensively considered
and the numerical solution was carried out by NTU-Le model. The system dehumidification amount per unit solar collector/PV panel area under different dehumidification and regeneration self-circulation reflux ratio (
) matching conditions is obtained. The results show that under typical working conditions (=1800 m/h
=4.0 kg/s)
the maximum dehumidification capacity
the system dehumidification capacity per unit collector area and the system dehumidification capacity per unit photovoltaic panel area are about 2.5 times
15.1 times and 6.2 times of the conventional system
respectively. The optimal dehumidification and regeneration self-circulation reflux ratio of the system is obtained by TOPSIS multi-objective decision-making method as (
) is (0.9
0.1)
and the system dehumidification amount is 4.61 g/s and the system dehumidification amount per unit total area is 0.28 g/(s·m). LDDS-SC system shows better dehumidification and energy saving potential than conventional solution dehumidification system.
