摘要
为了提高热管增效热电制水系统的制水能力,本文针对系统的结构尺寸参数开展优化设计,构建了经实验验证的系统优化模拟仿真模型,在给定热管及热电模块总传热面积条件下,以最大制水量为目标,分别对热管面积配比(γhp)及热电模块面积配比(γtec)开展优化设计。研究了空气温度、相对湿度及质量流量对系统性能、热管及热电模块面积配比的影响关系。结果表明:当空气温度、相对湿度增大时,系统的最大制水量随之增大,对应系统最大制水量的最佳热管面积配比γhp,opt和最佳热电模块面积配比γtec,opt分别为0.21和0.36;当空气质量流量为5 g/s、γhp为0.21、γtec为0.36时,系统制水量取到最大值110.5 mL/h。
In order to further improve the water generation of the heat pipe enhanced thermoelectric water generator(HPETWG)system,an optimal design for the structural size parameters of the system is carried out in this paper.An optimization simulation model has been established and verified by the experimental results.The optimal area allocation of heat pipeγhp and thermoelectricγtec,which is corresponding to the maximum water generation have been analyzed under the constraint total area of heat pipe and thermoelectric conditions.The effects of the temperature,relative humidity,and mass flow rate of the inlet air on the system performance,optimum area allocation of heat pipe and thermoelectric have also been discussed.The results show that when the air temperature and relative humidity increase,the maximum water generation of the system increases,and the optimal area ratios corresponding to the maximum water generation of the systemγhp,opt andγtec,opt remain unchanged at 0.21 and 0.36 respectively.When the air mass flow rate is 5 g/s,γhp is 0.21,γtec is 0.36,and the maximum water generation of the system is 110.5 mL/h.
