Abstract : in order to protect environment , it is very important to explore anew refrigeration method . for its unique characteristic , thermoelectric refrigeration is applied in some conditions . numerical simulation has been developed for the air - cooled thermoelectric air - conditioner by experimental simulation on heat - insulating materials with different thickness , structure - shapes , work - conditions and air - flow capacities . the model and the method have been verified . the effects of the figure of merit of thermoelectric material and the heat transfer coefficient of cool / heat side on the performance of the air - conditioner are analyzed by the model 文摘:建立了风冷热电空调器数值模拟模型,对空调器进行了模拟计算.在对风冷热电空调器研制的基础上,进行了最佳隔热层厚度、不同结构形式、变工况、变风量和复现性实验,验证了仿真程序的可靠性,并应用模拟程序对热电材料的优值系数和空调器冷、热端的传热系数进行了分析
This results showed the program can be used to simulate the variation of sewage qulity validly and exactly in a sewer which has the same characteristic with that sewer . analysing the real data and simulation data ss and xs decreased apparently ; xbh increased apparently ; snh , snd , and xnd have little variation 对西安市某污水管道进行水质测定和模拟,各组分实测值与模拟值的相对误差均小于5 . 0说明两者较为吻合,应用模拟程序可以对具有上述管道特征的排水管道内水质变化进行有效和较为准确的模拟。
