摘要/Abstract

摘要： 当前正压防护服功能相对单一，防护服内部温度较高且压力不易控制，安全性和舒适感较低，为此，提出一种集供/排气、过滤、制冷功能于一体的配套装置。测试防护服内保持微正压状态所需数据，分模块设计供气背包结构；对半导体制冷模块进行传热分析，建立仿真模型并基于计算流体动力学（CFD）分析型材尺寸对制冷性能的影响；以模糊PID控制保持温度、气压参数的稳定，求解传递函数、设计控制器并利用Simulink进行了仿真验证；搭建微正压防护服FLUENT仿真模型，分析防护服内流场、温度场分布规律以及供风温度对其影响；试制供气背包样机，并进行防护服温度湿度测试。结果表明，供气背包可实现30 s内除湿至正常环境湿度、100 s内降温至低于室温5 ℃。

Abstract: At present, the function of positive pressure protective clothing is relatively single, the high internal temperature and difficult pressure control resulted in low safety and comfort. Therefore, a supporting device integrating supply/exhaust, filtration and cooling functions was proposed. The data required to maintain a slightly positive pressure state within the protective clothing was tested, and the structure of the air-supply backpack was designed in modules. A heat transfer analysis was conducted on the semiconductor refrigeration module, and a simulation model was established to analyze the impacts of profile dimensions on refrigeration performance based on CFD (computational fluid dynamics). The parameters of temperature and pressure were stabilized by fuzzy PID control, the transfer function was solved, the controller was designed and verified by Simulink simulation. The FLUENT simulation model of micro positive pressure protective clothing was built to analyze the distribution law of flow field and temperature field in protective clothing and the influences of air supply temperature. The prototype of air supply backpacks was developed and the temperature and humidity of protective clothing were tested. The results show that the air supply backpacks may dehumidify to normal ambient humidity within 30 s and reduce 5 ℃ compared with room temperature within 100 s.

Key words: positive pressure protective clothing, gas supply backpack, semiconductor refrigeration, FLUENT simulation, temperature and humidity testing
