【摘要】：滚动转子式压缩机因为结构紧凑、工作可靠、容积效率高等优点而被广泛使用，它是空调的重要组成部分，运转效率的高低将直接影响空调的性能。随着制冷剂替代时间表的出台，各国纷纷开展制冷剂替代的研究，基于这样一个背景，本文通过对滚动转子压缩机泄漏损失的研究，分析不同制冷剂应用于滚动转子压缩机的容积效率。围绕这个主题，笔者通过以下几个方面展开工作：通过对文献和软件的查阅，分析了不同制冷剂的物理性质和彼此的优劣。针对不同制冷剂的性质，考虑压缩机对润滑油的特殊要求，选取了作为滚动转子压缩机制冷剂的合适润滑油。不同制冷剂具有不同的工作压力和工作温度，通过对制冷剂性质分析，设计了合理的压缩机结构尺寸，并对压缩机的吸气方式和噪声控制进行了一定的优化。泄漏量的多少严重影响压缩机的容积效率，，不同制冷剂不同间隙尺寸，压缩机的泄漏量也不相同，本文通过分析压缩机不同泄漏通道的泄漏机理，利用C语言来编写不同泄漏通道的泄漏程序，利用程序来计算不同制冷剂在不同泄漏通道的泄漏量，通过对数据的整理，得到不同制冷剂的容积效率。与现有压缩机容积效率相比较，来验证程序算法的可行性和有效性。不断优化程序，对以后制冷剂替代研究具有重要意义。
[Abstract]:The rolling rotor compressor is widely used because of its compact structure, reliable operation and high volumetric efficiency. It is an important part of air conditioning, and the operating efficiency will directly affect the performance of air conditioning. With the release of refrigerant replacement schedule, many countries have carried out research on refrigerant substitution. Based on this background, the leakage loss of rolling rotor compressor is studied in this paper. The volumetric efficiency of different refrigerants used in rolling rotor compressor is analyzed. Around this theme, the author works in the following aspects: the physical properties of different refrigerants and their advantages and disadvantages are analyzed by consulting the literature and software. According to the properties of different refrigerants, considering the special requirements of the compressor for lubricating oil, the suitable lubricating oil was selected as the refrigerant of the rolling rotor compressor. Different refrigerants have different working pressure and working temperature. Through the analysis of refrigerant properties, a reasonable compressor structure size is designed, and the suction mode and noise control of compressor are optimized to a certain extent. The volume efficiency of compressor is seriously affected by the amount of leakage. The leakage of compressor is different with different refrigerants and different clearance sizes. This paper analyzes the leakage mechanism of different leakage channels of compressor. The leakage program of different leakage channels is compiled by C language, and the leakage amount of different refrigerants in different leakage channels is calculated by using the program. The volume efficiency of different refrigerants is obtained by sorting out the data. Compared with the existing compressor volume efficiency, to verify the feasibility and effectiveness of the program algorithm. Continuous optimization of the program is of great significance to the future study of refrigerant substitution.
