【摘要】：随着技术的不断发展以及人们对空调使用的高需求,热力膨胀阀的性能提高受到了人们的极大关注。其中感温包的充注方式成为了关注焦点之一,感温包充注方式对扩大热力膨胀阀使用温区及提高工作性能有很大的影响,但是对于感温包充注方式的理论研究、数值计算等尚未有公开报道的文献。不同的充注方式以及充注液组分能够改善感温系统的工作性能。本文对热力膨胀阀的充注方式以及组分进行了理论研究与数值模拟计算。研究内容主要包括： (1)阐述了本文的研究背景以及热力膨胀阀组成、作用等,简要介绍了国内外热力膨胀阀应用、研究现状,以及热力膨胀阀感温包充注方式研究现状等。 (2)经过理论分析,对比各种充注方式,确定液体交叉充注在各方面具有很明显的优势,具有很高的研究价值。 (3)采用Visual Basic语言和EES进行编制程序计算,确定感温包充注液的组分以及各组分所占比例,对二元混合制冷剂、三元混合制冷剂的计算结果进行比较分析,确定适合的感温包充注液组成。
[Abstract]:With the continuous development of technology and the high demand for air conditioning, the performance improvement of thermal expansion valve has received great attention. Among them, the filling mode of the temperature sensor package has become one of the focus of attention. The filling mode of the temperature sensing package has a great influence on the expansion of the use temperature zone of the thermal expansion valve and the improvement of its working performance, but the theoretical research on the temperature sensing package filling method is also discussed. Numerical calculations, etc., have not been reported publicly. The working performance of temperature sensing system can be improved by different filling methods and filling liquid components. In this paper, the filling mode and composition of thermal expansion valve are studied theoretically and numerically simulated. The main research contents are as follows: (1) the research background, composition and function of thermal expansion valve are described, and the application and research status of thermal expansion valve at home and abroad are briefly introduced. As well as the thermal expansion valve temperature-sensing filling methods and so on. (2) through theoretical analysis and comparison of various filling methods, it is determined that liquid cross-filling has obvious advantages in various aspects and has high research value. (3) using Visual Basic language and EES to program and calculate the components and the proportion of each component in the liquid filled with temperature, the calculation results of binary mixed refrigerant and ternary mixed refrigerant are compared and analyzed. Determine the suitable composition of the temperature-sensitive filling liquid.
