The optimal performance state ' s parameter of thermoelectric refrigerator under different work conditions was obtained on the assumption that the temperature in the cold side is invariable . and , the optimal performance state ' s parameter of thermoelectric refrigerator under the third kind boundary conditions was also obtained . the transmission of heat differential equation for the heat conduction process of thermoelectric module was derived and the solution with the first kind boundary conditions under the influence of thomson effect and the solution with the third kind boundary conditions without the influence of thomson effect was obtained 在假设热电制冷的热端温度固定的条件下,得出热电制冷器在不同工况下的最佳工作参数并进一步求得在三类边界条件下的最佳工作参数;导出了电偶臂在电与热的偶合作用下传热微分方程,并对其进行解析求解:在考虑汤姆逊效应的影响下得出一类跟三类边界条件下传热方程的解析解,在忽略汤姆逊效应的影响下得出二类跟三类相的边界条件下传热方程的解析解。
The dissertation shows how a series of well - performing composite adsorbents that prepared by author suitable for the features of adsorption refrigeration are gained by using water and ethanol as cryogen ( adsorbate ) , which cause no harm to body and environment . the performance of the working pairs of water or ethanol with the composite adsorbents in the refrigeration through adsorption and desiccant cooling are thoroughly examined by experiments . the dissertation also examines , through energy analysis , the refrigeration efficiency and utilization ratio of the adsorption refrigeration , and analyzes the economic potential of the adsorption air - conditioning 以对人体无伤害、对环境无污染的水和乙醇作为吸附制冷工质，研制出适合于吸附制冷特点的性能优良的一系列复合吸附剂；对水或乙醇与自制复合吸附剂组成的制冷工质对的吸附式制冷和吸附除湿制冷的性能进行了深入的实验研究；用有效能分析方法讨论了吸附制冷循环的制冷效率和能量的利用率；对吸附式空调的经济性进行了分析。
In the construction industry there has always been a mismatch between the research investment and construction expenditure and this has lead the industry to proceed on a scale with an inadequate understanding of many aspects of construction , such as , deterioration mechanism for structures that has often meant that due allowance has not been made for practical repair and maintenance . however , notwithstanding this situation there have been encouraging signs that within the last twenty years the transition from the conventional materials to the more advanced materials is being spear - headed by the construction industry where over 30 of all polymers produced are now utilised in that industry 与传统的蒸气压缩制冷系统相比,吸附制冷技术由于具有一些独特的优点,近年来受到了制冷界人士的广泛关注,国内外在吸附制冷技术的发展上进行了大量的研究工作.本文简要叙述了吸附制冷的工作原理,对吸附制冷技术的研究进展进行了综述.近年投入实用的吸附制冷系统主要集中在制冰和冷藏两个方面,而用于空调领域的实践很少,这是由于现有的吸附制冷技术尚不能很好的满足空调的用冷要求,本文在分析吸附制冷独有特点基础上分析了其在空调领域的应用前景
