摘　　要：溶液除湿在利用可再生能源与低品位热能方面的优势显著,具有广阔的应用前景。文章为优化溶液除湿空气处理机组的调控效果提供了一种控制方案,针对温湿度独立处理机组中的除湿器与表冷器进行数学建模,利用MATLAB/Simulink模块对数学模型进行仿真模拟,分别以空气流量、除湿溶液温度(冷水温度)、除湿溶液流量(冷水流量)为调节手段,探究了其对除湿器(表冷器)送风含湿量(温度)的影响,仿真结果表明:除湿溶液温度和表冷器冷水温度分别对除湿器出风含湿量和表冷器出风温度有着最为显著的影响。同时文章通过台架试验对所搭建的仿真模型进行了验证,结果表明二者的送风含湿量相差15.98%,温度相差2.77%,由此可见,文章所搭建的仿真平台具有一定实际意义,可为相关的试验提供理论指导。Solution dehumidification has obvious advantages in utilizing renewable en-ergy and low-grade heat energy,and has broad application prospects.In this paper,a con-trol scheme is provided to optimize the control effect of solution dehumidification air han-dling unit.The mathematical model of dehumidifier and surface cooler in temperature and humidity independent processing unit is established,and the mathematical model is simu-lated by MATLAB/Simulink module,with air flow,dehumidification solution tempera-ture(cold water temperature)and dehumidification solution flow(cold water flow)as ad-justment means respectively.The influence of dehumidifier on the moisture content(tem-perature)of dehumidifier(surface cooler)air supply is explored.The simulation results show that the temperature of dehumidification solution and the cold water temperature of surface cooler have the most significant influence on the moisture content of dehumidifier outlet air and the temperature of surface cooler outlet air respectively.At the same time,the simulation model is verified by bench test,and the results show that the difference be-tween the humidity content and the temperature is 15.98%and 2.77%,which shows that the simulation platform built in this paper has certain practical significance and can provide theoretical guidance for related experiments.
