太阳能溶液集热/再生器是太阳能溶液除湿制冷空调系统中的核心部分，通过数值模拟的方法，对空气入口温度、湿度，溶液入口温度、浓度，环境温度等因素对太阳能集热/再生器的再生效率的影响进行了数值模拟分析。结果表明：将环境温度、入口空气温度、入口溶液温度由20℃增大至40℃后，对应的再生效率分别上升了0.745%、3%、93%。提高入口溶液温度能够最大提升太阳能溶液集热/再生器的再生效率。随着通入空气的流量的增加，空气流量由0.02 kg/s增加至0.14 kg/s，再生效率增加了31%左右，而随着入口溶液浓度由0.30增加至0.38，再生效率由0.55下降至0.43，效率下降了22%。随着太阳辐射由0.5 kW/m2提升至1.5 kW/m2，再生效率由0.58下降至0.44，效率下降了24.13%。

Solar liquid collector/regenerator is the core part of solar liquid desiccant cooling air conditioning system. The numerical simulation analysis was carry out for stduy the impacts of air inlet temperature and humidity, liquid inlet temperature and concentration,environment temperature on the regeneration efficiency of solar liquid collector/regenerator by numerical simulation method. The results showed that the corresponding regeneration effi-ciency is increased 0. 745%,3%,93% with increasing of the environment temperature,inlet air temperature,inlet liquid temperature from 20 ℃ to 40 ℃. The regeneration efficiency of solar liquid collector/ regenerator can be maximized with increasing of inlet liquid temperature. With the aeration flow is increased,air flow is increased to 0. 14 kg/s from 0. 02 kg/s,regeneration efficiency is about increased 31%,with inlet liquid concentration is in-creased to 0 . 38 from 0 . 3 ,regeneration efficiency is decreased to 0 . 43 from 0 . 55 ,the efficiency is decreased 22%. With solar radiation is increased to 1. 5 kW/m2 from 0. 5 kW/m2 ,regeneration efficiency is decreased to 0. 44 from 0 . 58 ,efficiency is decreased 24 . 13%.
